Human Growth Hormone (HGH) has long been viewed as a remedy for aging and the diseases associated with the aging process. Research published in the AMA Journal of August 16, 2000 links sleep disorders to a lack of HGH.
In an article on research undertaken at the University of Chicago, headed by Professor Eve van Cauter, published in the August 16, 2000 AMA Journal, a link was found between the sleep disorders in 149 men aged between 16 and 83 and the lack of Human Growth Hormone (HGH) in their blood.
This lack of HGH was found to be a possible cause of “middle age spread” in the test subjects, and they theorized that the lack of HGH in older persons was a reason for the typical build up of fat and the loss of muscle mass.
HGH is produced naturally in the body, particularly at night during deep or slow wave sleep, and this component of sleep in the men was found to decrease from 20% for men 25 years or younger when their HGH levels were highest, to 5% for those over 35. By the age of 45, the research found that the men had almost lost the ability to fall into a deep sleep once they had awakened during the night. It found that by 50 years, the amount of sleep had declined by 27% a decade. They also established that growth hormone secretion decreased by 75% over this period.
There was nothing to link the reduction in sleep to a lack of HGH – this research showed a counter link – that less HGH was produced by the body because of less deep sleep. However, HGH replacement therapy has confirmed that patients taking HGH do sleep better.
