Taking 40 winks in the middle of the day may reduce the risk of death from heart disease, particularly in young healthy men, say researchers. They studied 23,681 individuals living in Greece who had no history of coronary heart disease, stroke or cancer when they first volunteered, and found that those who took a 30-minute siesta at least three times a week had a 37% lower risk of heart-related death. The researchers took into account ill health, age, and whether people were physically active. So go ahead and nap — a short daily snooze might ward off a heart attack later in life. It is known that countries where siestas are common tend to have lower levels of heart disease.
