Hot flashes are no joke when they leave you soaked in sweat and feeling dazed. Technically, hot flashes exaggerate how the body normally cools down: blood vessels dilate, letting more blood reach. Help me understand what is actually going on in my body during a hot flash. It feels like a lot is happening.
Your hypothalamus—the part of your brain responsible for regulating body temperature (along with appetite, sleep cycles and hormones)—detects hormonal shifts and goes on alert, thinking that you’re overheating. Let’s have a look at the series of events that cause a hot flash. Your brain thinks that your body is too hot, even if you are not. The process by which your body cools itself (sweating) is initiated.
Blood vessels dilate to allow your blood to reach the surface of your skin. Your skin temperature rises and you feel hot. Your body gets a sudden, intense surge of warmth; sometimes skin turns red and blotchy. Your skin temperature climbs, beginning at the top third of your body (your face, head and chest). Blood vessels begin to dilate.
Your body struggles to regulate and reduce its temperature and cool off by perspiring. While nobody actually knows the mechanism for a hot flash, we do know that there is an area in the brain called the hypothalamus that regulates body temperature. For whatever reason, during the transition through perimenopause and menopause, the hypothalamus sends signals that cause women to get hot.

Medically Reviewed by Rosalyn Carson-DeWitt, MD. Last Update. Physiology of hot flashes Hot flashes are the most common symptom of the climacteric, although prevalence estimates are lower in some rural and non-Western areas. The symptoms are characteristic of a heat-dissipation response and consist of sweating on the face, neck, and chest, as well as peripheral vasodilation.
It’s a sudden feeling of heat and sometimes a red, flushed face and sweating. We don’t know exactly what causes them, but they may be related to changes in circulation. Hot flashes start when blood. A hot flash, or vasomotor flush, is when your brain mistakenly thinks your body is overheated and starts a chain reaction to try to cool it down.
This is probably caused by changes in hormone levels as you approach menopause.
