The sleep is not good to impel the man's middle age to put on weight
The middle age of perplexing a lot of men puts on weight the phenomenon relates to the fact that sleep quality drop, this is a new discovery of a researcher of University of Chicago. Between 1985 and 1999, the researchers of Chicago University have investigated the sleep state of 149 healthy men, their age varies from 16 years old to 83 years old. The investigation result reveals, the sleep during 35 years old to 50 years old of these men is basically steady, but deep sleep time is reduced greatly. The deep sleep time of the man under the age of 25 generally accounts for 20% of time of total sleep, pass for deep sleep time of 35 -year-old man every year but only account for 5%, has already basically lost deep sleep ability at 45 years old. Lead Fan of the research test special professor and say, the man will make growth hormone in the deep sleep, the time of deep sleep will lead to the fact to shorten growth hormone is secreted and reduced. They find the intersection of growth hormone and than reduce by about 75% when being young person who secrete of man over the 35, this may cause the putting on weight of most middle aged men. Fat pile up and waistline increase and not of flaccid muscles to relate to the fact that growth hormone is scarce. It still shows to study, total sleep time probably reduces 27 minutes every 10 years after the man is at 50 years old, they often wake up at the night, sober time is lengthened with growth of age after waking up. Researchers think, can test and inject the treatment and slow down the old and feeble sign that the man appears during middle age with growth hormone according to this new discovery. The growth hormone treatments are mostly used in the old man over 65 at present.
