Poor sleepers can cut their health risks by exercising more, reports a new study of 380,055 middle-age people in the British Journal of Sports Medicine. Both physical inactivity and poor sleep are independently linked to a heightened risk of cardiovascular disease, cancer and death, but Australian researchers found that more exercise lowers the consequence of poor sleep. People that ate better, drank less alcohol and were more physically active also tended to sleep better. The lower the sleep score, the higher were risks of death from any cause, including cardiovascular disease and ischemic stroke. Those at the bottom of the scales with both poor sleep scores and little physical activity had a 57 percent higher risk of death from any cause. People that were younger, female, thinner or better off financially tended to have healthier sleep scores, as did those that ate more fruits and vegetables, spent less time seated, had no mental health issues, never smoked, didn't work shifts, drank less alcohol and were more physically active.
