Could a little sleep during the middle of the day reduce the risk of a heart attack? An unrelated study earlier this month in the Archives of Internal Medicine8 suggests that the answer may be yes. In countries like the United States, afternoon naps are mostly for children. But they are common for adults in Mediterranean countries. And these countries generally have lower rates of heart disease. So scientists in the United States and Greece wondered if naps could play a part. Twenty-three thousand healthy adults took part in the study by Harvard University and the University of Athens.9 Those who took thirty-minute naps three times a week had a thirty-seven percent lower risk of death from heart problems than people who did not take naps.

　　The researchers say napping may improve heart health by reducing stress. They say the research suggests that naps are especially good for working men. But they say not enough female subjects died during the study to judge the benefits for women.
