Insomnia can be more than just a nuisance that makes it hard to get through the day; it may also contribute to a higher risk for mortality. A study of 1,741 people was presented today at a conference of sleep specialists: SLEEP 2009, the 23rd Annual Meeting of the Associated Professional Sleep Societies. Researchers found that men who have insomnia and get fewer than six hours of sleep per night were at highest risk of dying, more so than women (19.6% for men versus 10.3% for women).
This was a long-term study that followed men for about 14 years and women for about 10.
It’s important to understand that the two (insomnia and less than 6 hours per night) are the point of the study. Many men get less than 6 hours per night because of lifestyle or other situations (crying babies, noisy environment, etc). However, continuously getting less than 6 hours of sleep per night can have serious health effects as well.
