Most of us think we know what causes insomnia…
Too much caffeine…stress…jet lag…using a computer at night…napping too much.
A new study shows that there is another powerful factor that drives sleeplessness.
The research comes from the Columbia University Vagelos College of Physicians and Surgeons. Investigators analyzed records from 50,000 participants in a women’s health study. They compared rates of insomnia with data on diet.
