Many cases of narcolepsy are thought to be caused by a lack of a brain chemical called hypocretin (also known as orexin), which regulates sleep. The deficiency is thought to be the result of the immune system mistakenly attacking parts of the brain that produce hypocretin.

What hormone makes you sleepy after eating?

At the same time, the brain releases serotonin that causes drowsiness. Moreover, food also influences melatonin production in the brain.

What is food coma caused by?

There are a few reasons for this: a meal high in carbohydrates triggers a larger spike in insulin, which makes more tryptophan enter your brain. When that happens, the tryptophan first turns into serotonin, which makes you feel good, and then into melatonin, which makes you feel drowsy.

How is orexin related to sleep and wakefulness?

Orexin is definitely involved in arousal and wakefulness, for example, in getting sleepy or drowsy people to be more awake (with little effect on arousal in already rested individuals). In other words, orexin might be a way to combat fatigue in the future.

How does orexin play a role in appetite?

To sum up, orexin plays a role in driving eating beyond satiety and in sedentary behavioral inclinations, as well as in sensory sensitivity. In turn, these connect to exercise, environmental cues, emotions, and cognition. Put differently, our culture can drive our biology, particularly in the domain of appetite, into realms of excess.
