1. What causes drowsiness?
Sleep plays an extremely important role in human life, but we often do not know the exact cause of sleepiness, as well as the brain's mechanism of causing drowsiness. Some studies in rats have shown that astrocytes in the brain stimulate sleepiness by releasing adenosine, a neuromodulator whose sleep-inducing effects are inhibited by caffeine. Also, the longer you stay awake, the greater the urge to fall asleep. This is called sleep pressure.
Scientists also say adenosine is a contributor to sleep stress. This chemical builds up in your brain while you're awake, then stimulates the unique patterns of brain activity that occur during sleep. Unlike other neurons, these astrocytes do not fire electrolytes, and they are considered simple support cells.
In general, sleep-related problems stem from a variety of causes, including Jet Lag syndrome, night shift work, shifts that go against the body's natural sleep rhythms, or sleep little while.
Some people may feel tired from not getting enough sleep, while others suffer from sleep disorders, such as sleep apnea, restless legs syndrome or insomnia. Narcolepsy.
