Patients with this condition for a long period of time are considered to have a neurological disorder that may be caused by overexertion. Patients may also have a family genetic disorder that does not produce drowsiness. It is recommended that one should pay more attention to rest and relieve neurological fatigue through appropriate exercise. In fact, the brain produces drowsiness because the neurocentral system within the cerebral cortex is inhibited in some way to make people go to sleep, but if the neurocentral system is always in an excited state it will not produce drowsiness and will not go to sleep. If the patient has no sleepiness, consider that it may be a symptom of insomnia. In general, it is recommended that the patient should not put too much pressure on himself, keep his emotions stable, drink a glass of hot milk before going to bed, or soak his feet in hot water to help him enter deep sleep, and pay attention to the rest and relaxation of the body.
