What Happens To Your Body When You Drink Too Much Coffee

Up to 400 milligrams (mg) of caffeine a day appears to be safe for most healthy adults. That’s roughly the amount of caffeine in four cups of brewed coffee, 10 cans of cola or two “energy shot” drinks. Keep in mind that the actual caffeine content in beverages varies widely, especially among energy drinks. If you like drinking coffee simply for the pleasure of it, Harvard University research has found that sipping up to six cups a day is probably safe. Remember: Those are 8-ounce cups with about 100.

As a general rule, you can assume that an average 8-ounce (240-ml) cup of coffee offers around 100 mg of caffeine. Several sources suggest that. One cup typically equals about 70 to 140 milligrams of caffeine.

If you pop down to your nearest café and order a medium or large coffee, that’s not always one cup (eight ounces) — that’s likely. If you like drinking coffee simply for the pleasure of it, Harvard University research has found that sipping up to six cups a day is probably safe. Remember: Those are 8-ounce cups with about 100 milligrams of caffeine and little added milk and sweetener. But drinking six or more cups of coffee a day can increase your risk of heart disease by up to 22%, the researchers found.

About one in four deaths in the United States is due to heart disease. The Dietary Guidelines Advisory Committee looked at whether coffee poses any health risks, a topic they have previously been silent on. They concluded that strong evidence shows moderate coffee.

According to the Dietary Guidelines for Americans, it’s safe for most women to drink three to five cups of coffee a day with a maximum intake of 400 milligrams of caffeine. (Caffeine content can vary depending on the type of coffee, but an average 8-ounce cup has 95 milligrams.) But if you’re pregnant or breastfeeding, the rules are different. Still, it is typically harmless: Adults can safely consume up to 400 mg of caffeine per day — about four to five cups of coffee — according to the Food and Drug Administration. And natural sources of caffeine, such as pure coffee and tea, have been shown to have some health benefits.

Black and sugar-free coffee are very much keto friendly, although less than half of people would drink it this way. Organic always wins over non-organic, freshly ground over instant coffee granules and so on. Try drinking as much coffee as you like for a week, test your ketone levels and see if you stay in ketosis.

List of related literature:

It has been noted that about 200 to 300 milligrams of coffee a day, about the equivalent of two to four cups, is safe.122 It is not hard to exceed these safe levels.

Tons of research supports the mental alertness benefits of drinking coffee first thing in the morning, so anywhere from 300 to 400 milligrams of caffeine per day (400 mg = about 1 venti [20 ounces] Starbucks coffee) is A-OK (based on personal tolerance, though, so go with whatever works for you).

Unfortunately, most people average 238 milligrams of caffeine a day—the equivalent of two to three cups of coffee—and 20 to 30 percent of people consume a whopping 600 milligrams a day (about 71 percent of it coffee, 16 percent from tea, and 12 percent from soft drinks and energy drinks).

  • You have to drink coffee, literally every minute in order to die very fast in ONE SITTING. That’s for literally everything you consume. You can die from carrots if you eat to much and you’ll turn in Garfield.

  • Aaa, I’ve had that shortness of breath thing for 2 minutes, too, I think. But I have no idea what causes it, it’s really rare and random, and so inconsistent I’m pretty sure my doctor will just dismiss it. v_v

  • People who say “oH iT gIveS u eNeRgY” are the people that are heavily hooked on it. Coffee is first made in Yemen in 15th century, so you are saying people who lived before that are lazy zombies? Just go to sleep earlier, take some power naps and exercise. I don’t even know why people love to drink it anyway, it tastes like mud with burnt ashes in it.

  • Im glad i found this video, my nails have quite a few white dots on them and I’ve always wondered why.

Ive also wondered why they seem to come and go but that may well be just by hitting my hands

  • hi doctor mike, how are you? i love your videos so much… I have Hashimoto and that made my thyroid work less.. I take medications continuously and visit my doctor every 3 months.. my “TSH” changes a lot.. sometimes is good and sometimes is bad, I’ve been taking medications year and half.. I just wanna know if
    this sickness will ever goes or I’ll be taking medications for the rest of my life? thanks for your efforts

  • No way to overdose? dude one day i had 5 small cup of freaking espresso and my heart about to explode.
    So that’s why the waitress so confused why would someone drink that much of coffee

  • no it doesn’t I’ve been drinking 2 cups of coffee everyday and I’m still sleepy everyday, play roblox for a few hours, and fall asleep and wake up at 7:00 hehe

  • i literally drink almost 3-5 cups of coffee, the only bad thingbhappens to me is i see demons on 3am drinking with me, wdym nothings wrong

  • My dad stopped drinking coffe he took about 10 cups a day no joke im dead serious. I always wonder why he was so full of energy back in the days now i know why…. He did Never drink water or soda or anything but coffe.

  • Coffee is a strong stimulant to the stomach. It may cause heart burn/acid reflux, and as a result, coughing. Did any one experience that?

  • I gave up coffee and the following 3 days were like hell for me emotionally and mentally.
    I started crying for no reason then at times got very angry and irritable.
    It took me 3 and a half days to go back to my normal state of being.
    I drank a lot of water in the meantime to flush out all the caffeine out of my system.
    Also lime juice helped me to stay hydrated and calm.
    My advice would be if you want to get rid of your caffeine addiction and want to try it don’t go cold turkey at one go.
    Start by reducing the number of cups you drink per day.
    Lets say if you drink 10 cups/day reduce it by 2cups and drink 8 the next day and stick to your plan.
    You would need to dedicate around 3-4 days to completely decaffeinate yourself.
    And believe me,its totally worth your time and effort,especially for your mental health and pocket!

  • My entire life I’ve been around people that, no shit, will drink 6-7 cups of coffe every single day and nobody bats an eye to it. But replace that with juice, soda anything but water and it’s sounds crazy. But coffe is normal to drink gallons of every day

  • He states correctly that caffeine is drug, it’s addictive, it causes stress (adrenaline), it disrupts your natural sleep/wake cycle… but then says drink up? WTF! Is this video sponsored by the coffee industry? Young people watch this channel, such propaganda is irresponsible and dangerous!

  • I used to drink as much as 15 cups of coffee on certain days, strangely I never had problems falling asleep, yeah I didn’t feel tired but if I went to bed at 10 even after so much coffee I would fall asleep in minutes. I never experienced any side affects of too much coffee and till today I drink a lot of it, and I mean, a lot.

  • I had the issue with throat pain. It could be underdeveloped vocals, over usage of the vocals, too much tension while speaking, or singing. I got rid of mine by doing vocal warmups correctly and trying to speak more throughout the day. Vocal warmups such as the lip trill relax and warm up the vocals cords for speaking and singing.

  • wait i usually have one cup a day and i still feel tired even if i have two cups and when i stop drinking coffee i have no withdrawal symptoms

  • I’m italian and we are used to drinking espresso shots at night with no problem. I have 3 espresso shots in the morning into early afternoon and have maybe 1 or 2 more in late after noon…. I think I definitely developed a tolerance… are espresso shots healthier than American coffee? My dad always says espresso is good for the heart.. is that true??

  • My parents barely let me have coffee and when in do im bouncing off the walls and i shake like crazy while heart is going faster than lightning mcqueen

  • No matter how much coffee i drink it doesnt affect me anymoree
    I started to drink coffee when i was 6 so i guess its because of that?? Im not very sure

  • Coffee is good if you are going to do something or play games however if you took it and just sit there you might get some serious anxiety specially if you’re someone who have social issues like me lol i tend to think on to end some people’s life but it just i thought though XD

  • 7 days ago i took 800mg then went into the gym and after that I went running, then I came back home and fell on the floor with the worst body feeling ever, I was shaking and my hands were completely numb and my heart was pumping like 120 times per minute then I rushed to the hospital and as it turned out i was having a panick attack because my stomach was making too much adrenaline from the caffeine, 2 days later i had another panick attack but less simptoms ant yesterday yet another one but even less simptoms…..so caffeine is not goof for everyone, it stick in your body for like next 7 days but you get better

  • Drinking coffee makes me sleepy all the time, doesn’t make me feel energized at all… I drink coffee to boost metabolism (1 cup a day) also helps reduce hunger

  • Youtube really is the worst place for information but I’d rather drink coffee than drink soda. People seem to forget that people eat candy chocolate and drink soda like a newborn

  • With its stimulating effects, it’s easy to understand why coffee is the second most traded commodity on earth after oil. For many, it keeps us awake and moving through our busy days. But how does it work? What exactly does coffee do to your brain?

    2Whenever you’re awake, a chemical called adenosine slowly accumulates in your brain and this adenosine binds to receptors which slow down brain activity. Ultimately, the more adenosine there is, the more tired your brain feels. Which makes sense as the longer you’re awake, the more fatigued you become. Conversely, while you sleep, the concentration of adenosine declines, gradually promoting wakefulness.

    3 – But it turns out that the caffeine in your coffee is incredibly similar to adenosine in structure. The caffeine works its way through your bloodstream and into your brain where it starts to compete and combines with adenosine receptors. But because it’s not adenosine, the sleepiness effect isn’t felt. Adenosine can no longer bind, meaning its calming properties are diminished. Which is great for you when you’re feeling tired.

    4 – However, with long term use of caffeine, your brain responds by creating more adenosine receptors, which means more caffeine is required to elicit the same response. It also means that when you try to quit drinking coffee or miss your daily intake, you might experience some withdrawal symptoms and feel more tired than you would have before you ever drank coffee. But the caffeine doesn’t stop there.

    5 – It also stimulates the production of adrenaline – you know, the fight or flight hormone. This increases your heart rate, gets your blood pumping and even opens up your airways. Furthermore, it affects dopamine levels by preventing its reabsorption in the brain, which makes you feel happy. In fact, this is the exact same thing that cocaine does, just to a lesser degree. It’s a drug after all.

    6 – This dopamine stimulation is also the aspect of coffee that makes it moderately addictive. So, can you drink too much coffee? It turns out there is a lethal dose of caffeine, which is somewhere around 150 milligrams of caffeine per kilogram of your body. This means if you weigh 70 kilograms, you require 14,000 milligrams of caffeine to overdose.

    7 – Put into perspective, an average cup of coffee contains roughly 150 milligrams of caffeine. Meaning if you’re 70 kilograms, approximately 70 cups of coffee would kill you. However, you would have to drink those cups all at once, making it effectively impossible to overdose on caffeine from coffee, since you wouldn’t be able to physically fit that much in your stomach.

    8 – You would also start experiencing mania and hallucinations before getting to this point. Caffeine also has a half-life of around 6 hours. So, if you drank a standard coffee with around 150 milligrams of caffeine, after about six hours, there would only be around 75 milligrams left in your system and you’ll be feeling half of the effect.

    9 – And 6 hours after that, you’ll have 37.5 milligrams, leaving more room for adenosine to jump back into action, which is why you may reach for another cup throughout the day to remain that glorious alert and energetic feeling. So, drink up and enjoy the buzz while it lasts.

    10 – And for all of you who are in school, while we know that caffeine is key, so are good deals on textbooks. So, we’ve teamed up with slugbooks.com to get you the cheapest prices for the books you need. All you have to do is head to 10 – slugbooks.com/asapSCIENCE and search the ISBN number of the books you’re looking for. SlugBooks will then compare prices from all across the net.

    11 – Seriously, we know how expensive textbooks can be so hopefully this will save you some money. Got a burning question you want answered? Ask it in the comments or on Facebook and twitter, and subscribe for more weekly science videos.
