The Penn State Cohort Study of over 741 men followed for 14 years finds that men suffering from insomnia and sleeping less than 6 hours nightly had 4 times the risk of dying than men that had normal sleep. A trend of insomnia and short sleep coexisting with diabetes and/or hypertension brings with it increased risk of over 7 fold. In women their was no increase in deaths associated with insomnia or short sleep.
PositiveTip: If you suffer from insomnia do not ignore it. Set regular sleep/wake times, exercise daily at least 30 minutes, avoid caffeinated beverages, and skip late, large meals.
