But the brain scans revealed a complicated interaction between two basic biological processes: the body’s central “circadian rhythm,” which pushes people to be awake and active during daylight, and wind down when it gets dark; and “homeostatic sleep drive,” which pressures people to go to bed when they’ve been awake too long. By Amy Norton HealthDay Reporter. FRIDAY, Aug. 12, 2016 (HealthDay News) Both an internal “clock” and an internal “hourglass” affect how different parts of your brain respond to sleep deprivation, a new study shows..

The Belgian researchers said these findings could eventually aid in the understanding of sleep disorders, and help folks who work night shifts or those with jet lag. Circuits in the brain act as an internal clock to tell us it is time to sleep and to control how long we then stay asleep. A new study in flies suggests a part of that clock constantly monitors.

At two peak times in the 24-hour day, just before waking and sleeping, neurons in cognition-related brain areas packed a timekeeping cell’s. Hundreds of biological timekeepers live your cells, governing your sleep, appetite, behavior, and more. Here’s how to manage your circadian rhythm so it works best for you. Your internal clock, or circadian rhythm, is always running in the back of your brain no matter what else is going on.

This is controlled by the hypothalamus and is another part of how your body knows when it’s time to be awake or time to sleep. Your internal clock works best when you have built good, regular habits of sleeping. Two internal biological mechanisms –circadian rhythm and homeostasis–work together to regulate when you are awake and sleep. Circadian rhythms direct a wide variety of functions from daily fluctuations in wakefulness to body temperature, metabolism, and the release of hormones.

Both CAT scans and MRIs are neuroimaging techniques that allow us to understand brain structures. While the CAT scan relies on _, the MRI uses _ to produce images of the brain. A) radiofrequency waves; radioactive dye and x-rays B) radioactive dye; x-rays and positrons.

Taking into account both suppressed neurogenesis and failure to develop to functional maturity, the authors estimate that sleep deprivation reduced the new neurons in this region by 60%, supporting the role of sleep in enabling the development of the structural substrates of brain plasticity.

NO also appears to play a special role in neurons with rhythmic firingsuch as the brain stem and thalamic neurons that regulate sleep—wakefulness, and the hypothalamic neurons that control bodily functions with daily variations (circadian rhythms).

Neurons of the aminergic arousal system (serotonergic, histaminergic, and noradrenergic), and other sleep state– dependent neuronal groups, are also positioned to provide a source of tonic (nonrespiratory) drive to respiratory neurons across sleep–wake states.

Furthermore, if consolidation involves the transfer of information from hippocampus to neocortex (an idea developed further in Chapters 12 and 13), one might expect there to be increased interaction between cells in these brain areas during and after sleep.

Serotonergic neurons projecting to the suprachiasmatic nucleus of the hypothalamus help to regulate circadian rhythms (e.g., sleep–wake cycles, body temperature, and hypothalamic-pituitary-adrenocortical axis function).

Giuseppe Moruzzi argued that “sleep concerns primarily not the whole cerebrum, nor even the entire neocortex, but only those neurons or synapses, and possibly glial cells, which during wakefulness are responsible for the brain functions concerned with conscious behavior.”

  • Great videos Zac, very relaxing ��! Also love the absolutely beautiful scenery in your vids. Question: Does this work on pets too?? My hyper dog is fast asleep after 10 minutes…thank you ����!!

  • im feeling worthless and not good enough rn. i came to this video and looked at some comments. these comments mean so much and its crazy how strangers can make u feel better than people u know ��

  • I have IBS and lack of sleep gives me tummy ache and diarrhea, literally since I was a child,crazy and gross,I make sure to sleep as much as I can at night,for all my IBS people,make sure to SLEEP,it makes everything better with our sensitive tummies:)

  • They call it a “disorder” but it’s completely natural to the people (like me) who have it. The rest of the world, however, tends to think we’re lazy and doesn’t care that we don’t get enough sleep because work schedules are set up for “morning people.” I very much believe that the sleep deprivation caused by this has affected my health and makes me ill in other ways.

  • People in the comments: *inspirational and poetic
    Me trying to fall asleep at 3am on a school night: today I ate a slice of cheese, and it tastes like cheddar for some reason lol

  • We set the alarm at 4 AM every day for the first 10 days of
    Ramadan month.
    Initially, it was difficult to get up at such an early hour.
    Now we got used to it.
    With effortless ease, we get up.
    It is because of commitment!
    Because of sincerity!!
    Because we internalized the timing!!!
    It has become a habit or daily routine.
    The Inner Clock is set at 4 AM.
    It is ingrained in our psyche.
    Subconsciously, we get up.
    When Inner Clock is ticking, you don’t require alarm clock. you will get up automatically.
    When Inner Clock sleeps, no amount of external call can wake you up. You will press the button down.
    Once again you will go back to sleep.
    Keep your Inner Clock Ticking!!!
    All the time.
    Morning time is the best part of the day.

  • everythings is going wrong with me, everything is so dark from within, nothing is right, im stuck in the shade of overwhelming darkness…i am a fan of evil, but i do not like to dwell with it, and in this evil i am lost, in this darkness i walk, i hurt my closest ones, i lose everyone, and i cant fight it, it grew strong in me, it is stronger than me, i would like to end it, but i dont want to, i want to keep fighting, but i feel like i cant, im lost and i need guidance, i need a light in the end of the tunnel, so i can sprint to it, and than use the dark to dwell for good and not ruin, i seek for help, i seek for redemption, i seek…i seek for myself…..

  • My internal clock is all scrambled. I work the night shift now, which is about normal for me. However, when I worked at GoMart they had me on 2 night shifts and 3 evening shifts. This was done in such a way that I had to switch what pat of the day I slept twice a week.

  • My internal clock is to go to bed when the sun goes up.. it’s really weird. If I have absolutely nothing to get me up in the morning (like when I’m on vacation) My sleeping habits always goes back to the same thing.. Get tired around 4-5 in the morning, sleep until 1-2 in the afternoon.

  • Thanks for watching my latest upload with deeply relaxing binaural beats, hope you enjoy it ������ From where in the world are you listening? Let us know below!

  • If you happen to stumble upon this, I’d like to say I am so proud of how far you’ve come. Life isn’t easy but it’s definitely worth it. Let go of your anxiety, fear, doubt, worries, hate. Let love in. Let light in. Let this year be a time for transformation. Put your heart into the things that feel like sunshine. ☀️✨

    There are still good people in this world. ����
    Sending love and positive energy ��⚡

  • Whoa, I wonder if I have DSPD? 2-3:00 AM is when I get tired! And if you ask pretty much anyone I know, trying to wake my up is like trying to get a brick to tap dance. It’s impossible without persistence and imagination. XD I’ve been waking myself up at about 8:00 AM every day for a couple weeks, but even though I get sleepy and go to bed at midnight, it’s impossible to actually fall asleep until 2:00. Usually 2:00 exactly!

  • Every day i sleep about 48 minutes later

    Which cycles forward
    About 29 to 40 days like this
    I sleep my 8 hours every day no problem

    Day 1 i sleep at 00.00
    Day 2 00:50
    Day 3 01:36
    Day 4 02.24

    And so on……..

    I cant control irt
    It is not option
    Or choice

    What is this term is called?

  • This is like the nice comment section, since when were people that nice in comments or outside, all these comments are restoring faith in humanity:)

  • Circadian rhythm. Been able to change mine, all you need is coffee and a really free schedule so you can sleep during the day. The coffee is for night time.

  • Never thought I found my inner peace here.. Rejoice all living things! Let’s continue healing ourselves by this kind of sanctuary. All is well ��

  • When you wake up from this sleep tell yourself OUT LOUD “Today is the first day to the BEST part of my life.”
    It will be.
    Sleep well. Beautiful things are being set in motion for you.

  • I’d like to see a video on how people living at extreme latitudes like Alaska adapt to the extremes of light and dark present here. People seem to get by alright up here, so theres gotta be some science to explain that

  • Mama mia! Glad to learn “ 18:30 Highest blood pressure”. My routine physical checks are typically scheduled to 19:00; that helped the nurses to report on the high side. LOL.

  • I was the same as a baby except that I would happily stay in my crib and the play with a toy or talk to myself babbling. A spring warm sunny day when the sun is on my bed is when I crave to go to sleep and I usually have a nap because it’s too beautiful not to have a nap.

  • My body used to be an early bird back in 2016.
    My body has been a night owl since 2017 till this day.
    I fall asleep at 5 AM and wake up at 11 AM

  • Their was this odd tapping sound in the background of the music and it was super annoying and I couldn’t continue listening idk I guess I’m just weird or something but it really got in my nerves lmao ��

  • Yesterday night I slept with the lights on (square led fittings) and today my whole day was confusing during my classes!!! Can someone suggest a solution

    P. S. Let me tell you I had a complete undisturbed sleep of 7 hours, but still I felt unsatisfied!!!������

  • I don’t know when I slept listening to this. When I woke earphones was on me and phone was dead. After I charged and switch on the phone I found 2:43:45.. Such a deep sleep.

  • I’m from Texas and I moved to Georgia about 3 months ago. I have been staying up from 9-11 and waking up around 2 and I would end up having about 1 hour naps 3 separate times a day. Well this help me?

  • What i wanna know is….if i know i have to be up at 5am for work and i set my alarm….why i always wake up automatically at 4:58am…..but when i know i dont have work….i just sleep….thats what i wanna learn about….how that works like that….how do i always wake up minutes before my alarm

  • I am Close to 7000 km away from Home, in the Gambia. I Chose to come here, to try to build Up Life once more. Build it Up from Scratch after my Ex wife left me, the 2 years further i am now showed me Life goes on. When we got seperated i lost every materialistic thing you can Imagine. I felt personally into a deep hole, i thought there was no way Out of that. But Life showed me there is Hope and there is Light at the End of the Tunnel. Cause that what was left was Love, the Love to Not give in/Up, the Love to get Up and stand proud. To Show the beautifull daughter we created she has a Father. A guideline, a rolemodel someone to Look Up to. To Show her what strength is, to have the Courage to go to a Continent far away from Home. To do the unexpected when everybody thinks your Not going to make it, you prove them wrong. You Take responsabillity for your Life and that of your own Child. Cause who is going to Show your child how Things are done?!? Exactly, it is you and in this Case it is me. And you know what?!? I am fucking proud of myself, that I just did it and had the balls to take Action in Life. And trust me this was Not easy, but we are Not allone and when you want to succeed, and to move Forward then also you will move Forward. The strength any of you out there have lays deep within in any of you. And you can do it, but you personally need to want to do it. And believe in yourself, you are remarkable and Not known of your capabillity and the real strength in you.

    I forgot to Love myself after i was Not Loved anymore. But Trust me you can Love yourself at any time. Cause you are damn worth it my Brothers and Sisters!!!

  • My internal clock is all screwed up, I use to have a hard time getting to sleep but now it’s staying asleep, I only get about 5 hours of sleep now, I think it’s because of my gf Cuz she kept waking me up n now my body wakes up on it’s own, I think she fucked me up, if anyone knows how to fix this plz hmu, thanks…

  • i suffer ptsd and ive been listening to this kind of music to try to sleep better and it really helps with diminishing flashbacks. sometimes they get bad to the point where i flail and hit the wall and they’re especially bad at night when i close my eyes. this music has helped me greatly thank you

  • 2 years ago I was in a car accident was t-boned but a 18 wheeler, was pronounced dead heart stopped and all but they shocked me back to life. I spent almost 3 months in the hospital finally went home never thought I’d get it but I had severe PTSD couldn’t sleep without having night terror then the woman I was suppose to marry was caught in my bed with another man the split of terrible, all that depression worsened my PTSD I had a mental breakdown was diagnosed with Bipolar stress disorder I’ve been having it hard then I found this community seeing how such kind saying nice things to each other I swear when I’m having a hard day I love coming to these videos and seeing all the nice and thoughtful things said amongst this community. I’ve also found love too she been a Saint she picks me up on days that I’m down try’s her best to put up with my Mental Illness she’s always asking “how’s my mental and if I’m okay” emotionally checking up on me because her and this channel I sleep all night now, I would get up every half hour when I was having night terrors. So lastly thank you all, people like you make the world on round and it’s nice to know that there’s still Sweet People in this world
    Love Peace Respect��

  • If you read this, I love you and see the light in every ounce of Star dust you are made of. The whole world is inside of you. Shhh, just breathe.

  • God I havent forgot how you took care of me when my momy died and I was a little girl. I just wanna thank you, for Always being right there beside me. My suffering these last few years have Not changed my gratefulness lord… you bring me Peace, I love you jesus ��

  • I’ve worked night shift for about 12 years. It took about 2 weeks to get used to sleeping during the day. The whole trick is blackout curtains and actually letting yourself sleep. Over the years, the biggest problem I have seen with night shift workers is refusal to sleep. They find excuses to stay up far too late into the day or get up much too early in the afternoon, and complain about the lack of sleep. If you have 16 hours from the end of one shift to the beginning of the next, you can find time for a solid 7 hours of sleep somewhere in there.

  • Wow, this is great stuff very beneficial for my state of mind allright…
    Like some huge accordion musicsloweddown a billion percent…
    Boy is that uplifting……
    Quick where’s the box of Rockabilly CD’s…….!!!!!!!

  • I loove your channel i listening from South Africa..i have bouts of insomnia n since discovering this channel i know what regular normal uninterupted sleep feels like

  • Are you happy with your life? If not, it need not have to be that way anymore. There’s just so much waiting for you out there. Stop clinging to what’s making you depressed. Wake up tomorrow and find your purpose. You can make life begin any moment ❤️

  • I would love to sleep at night time. But I am unable to fall asleep before sunrise. I don’t even sleep through the whole day. Only until noon, not more than 5 to 6 hours a day. I have big eye bags. But I still am unable to sleep in the night. It’s not because of social media. Sometimes I try to fall asleep but I only end up lying on my bed for like 3 hours without falling asleep. I theorize it might have to do with my anti-social personality. Mornings are the busiest time of the day. They are filled with people. This is why I end up staying awake during the night where there are almost no people and sleeping through the morning.

  • Biological Alarm Clock: Biological alarm clocks are biological mechanisms that tell us when to eat, when to sleep, and when to make babies. For women, oftentimes the biological clock goes awry, and begins to signal all sorts of jarring behaviors that seem at least to the man of the house to be most untimely. This biological alarm clock jolts a woman into action, or more likely, into prodding a man into actions at the wrong time. A woman’s biological alarm clock is often out of sync with her husband’s own biological clock, which naturally runs much slower. The man compensates by resetting his own clock to give himself more time. Unfortunately, women have no capability to reset their own clocks. This results in their ringing just in time to tell their husband to vacuum the floor as he settles back to relax from a hard day at the office, or to mow the law or bath the kid just as the big game comes on TV. All too often the wife gets all wound up just as the husband starts to unwind. Unfortunately, the only way to set back your wife’s clock is with a blunt object to the head. However, this is not recommended since it would set her back in time permanently, and force you to do time, as in jail.

  • I have and had many panic attacks. An d I hope this music will help me to sleep better and to feel more the hand of God in my life. Thank you so much for the nice comments and this beautiful music..

  • I play this to fall asleep and it has helped so much…just wish this particular delta wave sound mash up could be longer than 5 hours

  • Well, my internal clock is pretty fine when I was young. But now, it’s all haywire… screw it.

    Sleep from 22:00 to 23:00, can take as long as an hour for me to fall asleep, wakes up at 5 (everyday, no alarm). This always makes me sluggish in the morning.

    And if I slept sooner, say, like an hour earlier, I’ll get headaches for as long as I’m doing it.

  • I’ve had similar conditions before. I sleep at 6-9 AM and wake up at 3-6 PM. An easy fix for me is to just, stay up all night to get tired and then sleep at whatever time I want. Then the problem is fixed for me.

  • Funny enough I’m watching this at 12:48 on a school night but I’m still not going to sleep time to watch some videos about other science type things

  • Hey there, The best results that my step-mom has ever had was when using Jims Simple System (i found it on google) It is the most helpful plan out there.


  • i seem to always go to sleep at 5 to 8 am. sadly  I cant switch back to days for longer than a week or 2 without slowly switching back to being up at night

  • Remember that in ancient past our ancestors sometimes had no choice but to stay awake and run for their life when some hungry carnivore was looking for midnight snack… I like 2 pm naps

  • Your music is so beautiful, it instantly washes calm and relaxation over the mind. Reading the comments here, what strikes me the most, is seeing how much your music connects people all across the world. Those struggling to get to sleep, those trying to get some rest, every corner of the world, and everyone so kind and caring for others. Thank you, not just for the music, but for connecting us all.

  • Not everyone naps. I almost never do. And I’m always groggy until about Lunch.
    Also if you live far up the winters are almost all night. So that’s a problem.

  • mine is completely fucked up; i just spent a month waking up at 5 PM and going to sleep at 8 AM. Now I wake up naturally & without the alarm clock at 4 AM and feel VERY tired/sleepy around 6 PM:(

  • can you help me please
    my internal clock is messed up
    i stay awake all night, sleep in all day
    when i wake up i’m always tired
    is there anything i can do to change that??

  • Heya, The best outcome that my mother has ever had was when using Jims Simple System (i found it on google) It is the most incredible program available.

  • My sleep pattern is completely off.

    During long breaks and weekends, I sleep around 1-2 am and wake up around 9-11 am. I take naps at 5-7 pm.

    During school days, I sleep at 5 or 6 pm and I wake up around 12 am and start working on projects, assignments, etc. I usually sleep by 2 or 3 am and finish the rest of my sleep or not sleep altogether.

    Should I switch back to regular sleep schedule or retain this? My school performance doesn’t really change much.

  • Oh my god thank you! I have a majorly shifted intednal clock. So much so that its basically impossible to do school. All summer i was up till 5ish am and slept to 3-5 pm. So now that schools starting again, and my parents wont let me do medication, i have to stay up 24 hours every month to reset my clock to the “normal” one. FeelsBadMan

  • DSPD!!! That’s what i have! Maybe… i could move to a timezone that’s 3hrs behind so that i’ll feel sleepy by 11pm like “normal” people but normal sucks.

  • My husband is in the hospital, very sick. I am alone, disabled and pain filled, not able to work enough hours to support myself if he dies. Sorrow and fear and anger. This is helping me unplug from these horrid thoughts. Perhaps I can sleep.

  • Hey, is it possible if you make a video of how to resets body clock cause mine is too way off i cant sleep at proper timing and cant wake up at proper timing. Means like i sleep more than 8 hours a day

  • My internal clock is really messed up. First of all, I sleep in a deep relaxing comatose state for at least 9 1/2 hours uninterrupted. I was unemployed for 5 months in 2012. I found that I would sleep 9 1/2 to 10 hours a night and each night I’d stay up 1-3 hours later and later each night.

    For example:
    Night 1: Zzz @ 3am, wake at 12pm
    Night 2: Zzz @ 5am, wake up at 3:30pm
    Night 3: Zzz @ 7am, wake up at 4:30pm
    Night 4: Zzz @ 8:30am, wake up at 6pm
    Morning 5: Zzz @ 10am wake up at 7pm
    Afternoon 6: Zzz @ Noon, wake up at 6pm (I start battling backwards now)
    Morning 7: Zzz @ 9am, wake up at 3pm
    Night 8: Zzz @ 6am, wake up at noon
    Night 9: Zzz @ 3am, wake up at 12pm (repeat process).

    At the end of a couple of 6 hour sleep nights, it’s unbearable and I’m ready to go to bed earlier, but the night after a full rested night’s sleep, I’m back to staying up late again.

    Now, I don’t think this is a damn disease or anything. I think I’m just highly disorganized and preoccupied. Society loves to slap labels on anything and everything nowadays. I just attribute it to being a night owl, plain and simple, but I gotta be mindful that I don’t let it get out of hand.

  • ive been going to bed at 7am and waking up at 5pm, when i try to sleep before 11 im just up rest of the night not getting any sleep, and ive tried staying up all night until that certain time comes to try to sleep but it doesnt help

  • I have shool that starts at 08.30 tomorrow but still here I am again awake at 03:00 and not feeling tired at all I just can’t grab myself to start sleeping good

  • Pink Floyd was cutting edge on this stuff.. best go to sleep music is just go to sleep. All gadgets and gizmos off and all unnatural lights off.

  • I have a weird ass circadian rhythm, I wake up at around 8 A.M. and then at around 1 until the rest of the day I am extremely tired. Then at around 7 I get less tired at 1 I am fully energized.

  • It is ok for you to chose yourself. Put yourself first, and know that what ever is bothering you, or keeping you up can be addressed tomorrow. It is ok to unplug, to unwind, to let go.
    Your health and well being is most important; everything else can wait. Remember to take deep breaths and let your worries and anxieties go. All is well, and all will sort itself in the morning. Sleep well knowing you don’t have to figure it all out tonight.
    I hope you have a great day tomorrow

  • So now we know that it is completely normal and natural to feel sleepy in the mid-afternoon. Most office jobs prohibit the practice of taking a power nap in the mid-afternoon. They generally make this restriction based on the ignorant prejudiced belief that if you sleep during the workday, then it means you are lazy or that you did not get enough sleep the night before. This prejudiced belief is pure nonsense.
    If you are on the job in an office job and you feel sleepy due to short-term fatigue, then you are unable to do any productive work. The only way to become productive is to refresh yourself. The only way to refresh yourself is to take a short nap. In Japan, office workers are allowed to nap during the workday. It is not considered “lazy” in their culture. Their cultural belief is that if someone is napping during the workday, it is because he worked so hard. Some people fake it. I hate it when ignorant prejudiced people tell me that I need to see a “doctor” if I feel sleepy during the workday.
    If I give someone a car and $1000 to buy gas and tell him to drive from NY to LA and refill the gas tank only ONE time, then it will not work!

  • yes but WHY is Circadian Rhythm “Synced” with the cycle of the rotation of the earth?
    Generally speaking, we become conscious or “rise” with the suns appearance, and we hibernate with its disappearance. Is it purely from light stimulation being that the sun is out, thereby stimulating consciousness? Light photon induced consciousness? Consciousness still occurs at night, but is it diminished? Where are these studies published?

  • My internal clock is just the most accurate clock ever, because I can sleep and then wake up at exactly the time I’m suppose to wake up which is 7:30 on the dot XD

  • My internal clock (or as my family says it, “body clock”) is the worst in the family. I go to sleep around 2 am on school nights and 4-6am on non-school days, and have to wake up at 7 for the bus, or otherwise at midday or late morning. The thing is though, I don’t go to sleep because I’m tired, I go to sleep because I have to or else I’ll be told off by someone (usually a parent) because I just stayed up the whole night. I also can’t get to sleep before 3 on most nights. I do occasionally make an effort to try to sleep earlier, but then I can’t. Well, it’s great to know that it’s not insomnia (as my mum suspected).

  • Sleep deprivation (because most work/school is set up for “morning people”) can lead to adrenal fatigue. Then it’s a vicious cycle.

  • My internal clock is screwed. Wake up at 3pm, my body thinks dinner time is breakfast, then at midnight I feel like having lunch. Then at 3 or 2am I feel like having dinner. The I go to sleep at 4-6am. And it starts over again. I have no idea what’s going on..

  • Best sleep ever! Was going through a random bout last night and I woke up at 4am. Nothing else I played seemed to click till this one. I was out like a light in no time. Thank you ��

  • for some reason, i can function much better at night. feels like my mind is more awake and i also get sick.. well never, unless i’m awake during the day.

    also my sleep cycle only takes one night to flip over from night or day.. so if i can’t sleep one night i wilk be up every night and if i can’t sleep one day i will be up everyday.

  • hi! remember that I love you! ive always had, time just didn’t come to show you how much i do, but now it has! god is watching you from up okay? don’t do things you shouldn’t be doing, don’t harm yourself, don’t be scared to talk back to anyone! if they can have the audacity to yell at you, shoe them that you aren’t any less. just don’t bring it up to a point where you regret it! you’re awesome, just the way you are, understand? and you don’t need to change for anyone. not even the person you love, they can change their heart. sometimes, it’s better to let others go..even tho you might have to go through a long time to recover, god removes people from your life because he hears conversions you didn’t. always remember that they’re are people who care for you, you might not see it in front of your eyes but they do, i do. you might also be the person yelling at others, thats fine! no need to be scared of admitting, I know times might not be the best for you, but you don’t wanna be like the person who did this to you, do you? how about venting anger at an object next time? not you or anyone else okay? life might be rough right now, I understand. some situations..I might not. remember that even if you don’t get the gift you want, the best gift is life, okay? its okay to cry, it’s okay to express feelings, it’s okay to listen to sad tunes, it’s okay to be in love, its okay to be different. go look in the mirror, what do you see? a beautiful gorgeous human being. sometimes being with the people you love is good, sometimes being alone is fine as well. dont be scared to go in front of people, don’t stay inside all the time. you need to be confident, and pretty. because pretty is from the inside, not from the outside. trust me when I say you can get through this, we can. times will change, these type of days will be over. try to have fun while you can, try to spend time with your loved ones safely, while you can. sadly, these days will be over once. but don’t worry, you all will meet eachother in a nice place with only good feelings, you have a whole new journey in front of you. it’s not over, and it’s never been. okay? we all are normal, different, human beings. we all have a side to us that no one’s seen. which is good because everyone does! no need to be scared, there’s a bunch of people you can talk to! that’s only when you want to, or you can keep it to yourself! remember, there’s a voice in your head, talk with it if it makes you feel better! just remember that you ARE loved, you ARE normal, yes, you ARE different, we all are. now keep that gorgeous smile! it looks awesome on you

    i love you
    now say it back!


  • Biological Alarm Clock: Biological alarm clocks are biological mechanisms that tell us when to eat, when to sleep, and when to make babies. For women, oftentimes the biological clock goes awry, and begins to signal all sorts of jarring behaviors that seem at least to the man of the house to be most untimely. This biological alarm clock jolts a woman into action, or more likely, into prodding a man into actions at the wrong time. A woman’s biological alarm clock is often out of sync with her husband’s own biological clock, which naturally runs much slower. The man compensates by resetting his own clock to give himself more time. Unfortunately, women have no capability to reset their own clocks. This results in their ringing just in time to tell their husband to vacuum the floor as he settles back to relax from a hard day at the office, or to mow the law or bath the kid just as the big game comes on TV. All too often the wife gets all wound up just as the husband starts to unwind. Unfortunately, the only way to set back your wife’s clock is with a blunt object to the head. However, this is not recommended since it would set her back in time permanently, and force you to do time, as in jail.

  • During school days, I follow a semi-nocturnal sleep pattern. During breaks (spring, fall, winter, summer), I follow a full nocturnal sleeping pattern. During weekends, I follow a “normal” sleeping pattern.

    Monday-Thursday: Semi-Nocturnal
    Friday: Alternate between semi-nocturnal and “normal”
    Saturday-Sunday: “Normal”

    Long Weekends/Breaks: Nocturnal

    pretty messed up but it works well for me…

  • now i understand the name of my medication Circadian. My body clock is messed up so there for i need to take Circadian or Melatonin to try fix that

  • My spouse and myself are different.
    He’s up early, and really gets things done early. I’m not even tired at 6pm, when he is, I have a lot more energy in the evening.
    I have tried, for years to fall asleep at 9PM on his schedule. I just can’t and I feel wired…
    He makes me feel bad for waking up late, and doing things late… hey now!
    I don’t rag on you for doing things early and loud in the AM.
    Our bodies, do what they do… they know our rhythm. They can’t all be exactly the same!

  • This is my default location.. thanks for being the channel for our peace and healing. To everyone out there ‘If you’re in a pit, don’t furnish it’
    Sending out love.. and not because I’m fluffy ��.. but because that’s everyone’s default setting before we go through the lessons.
    Let go.. and it will let go of you.

  • Heh I just found out I have DSPD. It’s really hard for me to goto sleep during the night and sunlight makes me sleepy. So I always try to take night shift jobs and use caffeine to stay awake during the daylight hours. I always thought I was just a night-owl but it seems I was born different from the early-birds. So much makes sense now to me I have been dealing with the symptoms sense I was much younger I had ADD when I was child and was given Ritalin any chance that triggered the DSPD?

  • so, if i almost changed my sleep rythm to the complete opposite, being awake when its dark and sleeping when its day, does that mean i can basicly kms cause i will get sick? its been like this for years now

  • lol my internal clock is weird i can’t go to sleep before 3am but the alarm clock gets me up so i don’t have dspd but still can’t sleep before.

  • I’ve been pushed away from everyone I’ve met in my life. I never felt what being loved feels like or what is it like to have family that loves you. I know I was just kid but I felt being treated differently, I can see it, I felt it and I cried before I go to sleep at the 5 years. Why would you make a child feel unwanted, not loved, and telling them that you wish they never existed? Why do you have kids if that’s what you gonna do? Telling them you are a loser, not like your siblings, your cousins are much smarter. I remember all the negative things my parents said to me. Because that’s all I remember, because that’s all they said negative things. What’s this life if I don’t have a family, friends, or anyone to talk to? Is that why I was brought this life for? Suffer and see everyone successful except for myself, and to be lonely and alone in this cold world? I will already have struggles with everything outside. And to go back home to add up to my struggle more struggle. I’m 28 no friends, no love, and no family. That’s why I just listen to music and cry myself to sleep every night.. Wishing this suffering will end and wishing I never existed. It’s ok, it’s my fault, I always blame myself, even for the things I never done.

  • i need real help here. i have an exam in may 2017. im studying math. but im studying only nigt times. im sleeping till 17.00. and my brain activity is very good during the night. when the day time, i can not focus, im sleepy. i tried to change it but i couldn’t. and im totaly free about hours. i dont work (i had a break from job). my exam will be at 09:30 o’clock in morning. can i get sucsess by studying only night. somebodys are telling me that my brain will be sleeping at exam hour..because i always sleep at that hour. and i don’t believe it actually.
    im waiting all sugestions till may 2017:)

  • I need healing, I’m 26 years old and for the last 4 years ive been experiencing so much pain, anxiety, depression and fatigue. I’ve been diagnosed with very little testosterone and fibromyalgia. Everyday I wake up feeling exhausted and lightheaded in pain. I started receiving testosterone therapy two weeks ago but I haven’t noticed improvements. Please pray for me, all I want is to be healthy again. I’m so depressed and anxious, I’m in need of a miracle.

  • Strangely enough, I’ve never had problems with my sleeping cycle, even though it’s kinda weird.
    During the semester, when I have to wake up in the forenoon, I usually manage to go to bed around 2 to 4 AM which is enough. If I need to wake up sooner, I can also go to bed earlier without too big of a problem.

    But when left to myself, my sleeping cycle gets more and more out of sync with the real world where I go to bed at 4 AM, then at 6 AM, then even later…
    Hell, I once went to bed at 1 PM and woke up at 11 PM, just because I felt like it. A friend of mine actually managed to do the same, but continued going to bed later and later until his sleeping cycle has actually turned around an entire 24 hours.

    Not sure what went on there, but he reportedly felt completely fine and that had absolutely no ill-effects.

  • My circadian rhythm is reversed. I sleep from 7:00 am to 3:00 pm. I usually feel fine but I just wish I was in sync with the rest of the world.

  • I have no internal clock if i don’t try to go to sleep one day i’ll go to bed at six am next 3 days 630 next week itll be 7am and pretty soon im waking up at odd hours like 7pm this when i really start trying to go to bed early again…

  • I was studied at MIT and my circadian rhythm was found to be upside down. I come fully awake at night when it gets dark and during the day I am just a lump of crap. This is why I usually work this evening or overnight shifts in medicine. My mother thinks that I can turn this around so for 2 years I got up early in the morning and went to bed early at night and I felt like doodoo and never got used to it. I am at my best at night so what say you to me?

  • I am an undergraduate psychology student and in the table diagram showed in the video, it says our highest body temperature is 19 00. So why did he say in the evening as the sun disappears, our body cools down? Sun normally set around the 6 pm the the tropics for example. So the body temp cannot be cool down at this time. It would be great to clarify specific times and be more precise in those crash course video.

  • Whenever I don’t have work/school I always shift to going to sleep in the morning and waking up in the evening.

    Also alarms don’t seem to do anything. I turn them off but I can’t remember doing it.

  • Very informative video Dr Rege. Looking forward to the next parts. Would love if you could talk about insomnia in autistic individuals
