Shift Work May Raise Heart Risks for Women

Women who work irregular shifts may raise their risk for a heart attack. Researchers think that this increased risk is due to the stress of constantly disrupting the body’s internal clock.

This study observed more than 121,000 women ages 30 to 55. None of these women had ever been diagnosed with heart disease or stroke. The study focused on nurses, since many nurses work irregular shifts.

Women who had worked rotating shifts for more than six years faced a 70% higher heart attack risk than those who worked regular hours.
