Lack of sleep may hit women harder than men. New research finds it raises a woman's risk of heart disease more than it does for a man. Other studies have suggested that people who sleep less than five hours a night have an increased risk of dying from cardiovascular disease.

Why the risk is greater in women is not yet clear. There is speculation that differences in hormone levels may be key.

This latest study is based on data from more then 4,600 men and women details are in the journal Sleep.
