The human body requires different sleep time at different ages, for example, a newborn baby, most of which is in a sleep state, can reach 20-22 hours of sleep in a day, childhood needs 12 hours, adolescents are reduced accordingly, at 8-9 hours, to 6-8 hours in adulthood. If you sleep for a long time more than 10 hours, it may cause the following effects: 1, sleep rhythm disorders: the body has a normal circadian pattern, long sleep beyond 10 hours, resulting in longer daytime sleep, but lead to the night is not easy to sleep, late sleep, but also on normal life; 2, physical debilitation: the human body activities when the heart rate, blood circulation will be correspondingly accelerated, can increase Myocardial blood displacement, the resting state of blood displacement decreased, the contraction force is also weakened. It may destroy the contraction and beating frequency of the heart itself, and it is easy to have panic and shortness of breath, easy to wheeze and exertion during activities; 3, neurological impact: too long sleep time, the nerve center is more in a state of inhibition, and the patient may feel drowsy in the head and less energetic after waking up; 4, memory loss: too long sleep time, the brain cell activity decreases, and the sleep center inhibits other Nerve center function, not conducive to thinking, long will affect the brain memory capacity; 5, abnormal muscle tone: rest time is longer, the human body muscle tone weakened, wake up will feel limb weakness, lack of strength; 6, the formation of blood clots: sleep too long will slow down the blood flow in the body, long-term even lead to the formation of blood clots, and then induce cardiovascular disease.
