It is apt to cause people to be old and feeble ahead of time not to have enough sleep
The modern works more hard in the daytime, there is many night life, this leads to the fact the time of sleep is very late, or all possible all night. The consequence not having enough sleep, it is the people's immunity that is reduced, old and feeble ahead of time, so that the good hair one hundred is ill.
It is proved that the research group of University of Chicago must publish a report recently, time of the modern's average sleep has lacked to the person 90 years ago for one and a half hours, this makes the modern easier and older and feebler and having disease.
The research object of this research group ranges from 18 to the 27 -year-old healthy man for 11 ages, let them sleep 8 hour every day three day while being the first, sleep on 4 hours will it be every day six day while being following, sleep for 12 hours in seven days again, other diet respects are the same. After they wake up, the intersection of researcher and rate of metabolism measured for them one by one, surge disorderly level and the intersection of glucose and person who able to bear. The researcher finds, when their sleep is insufficient, eat the high carbohydrate meal for them, they need to adjust the blood glucose level to normally many 40% of the time than usual, they secrete and decompose insulin and will slow down by 30% than before at the same time, similar to symptom of the early diabetes. Lack and sleep growth and operation that will also influence other hormone, hinder being secreted by amazing hormone of thyroid gland, and increase the tense content of surging disorderly cortisol in the blood, more outstanding in the afternoon and time of at dusk especially. Cortisol can regulate blood glucose, regulate protein in muscles and the skeleton, controlling distribution of the fat,etc., the elderly will usually present cortisol to increase, the result causes memory to decline.
However, research reveals, after the person interviewed sleeps totally for 12 hours, the situation will be transferred to normally. Researchers explain: Not only will accelerate the human body oldly and feebly, but also will increase the morbidity of suffering from disease related to age if not having enough sleep for a long time, for example diabetes, hypertension and memory fail. Even a man in the prime of life, if only sleep for 4 hours every night, will meet the question of some metabolism. The people of the developed country sleep for 9 hours on average every day on beginning of this century, but the change of modern's life style, so that only sleep for 7 and a half hours every day.
There is sufficient sleep with good quality that not merely will give somebody energetic spirit, still can guarantee normal metabolism function of the human body, reduce the emergence of disease.
