Cause of drowsiness

Common causes of drowsiness include lack of sleep, poor quality of sleep, large changes in blood sugar levels between 30 minutes and 1 hour after meals, hypoglycemia due to hunger or dietary restrictions, and disturbance of the autonomic nervous system due to stress.

The autonomic nervous system is closely related to sleep. During the day, the sympathetic nervous system activates the body, but at night, the parasympathetic nervous system shifts the body and brain into rest mode, leading to sleep. However, this switching is not performed well due to stress and disturbance of the rhythm of life.

Hormonal imbalance is especially common in women. During menopause and menopause, estrogen levels drop. As a result, your resistance to stress decreases, which in turn leads to poor sleep quality and sleep deprivation.

The second is "idiopathic hypersomnia," in which a person falls asleep during the day and does not wake up even if they try to wake him/her up. The third is "recurrent hypersomnia," in which periods of somnolence and normal states alternate for several days to three weeks.
