Share to ClassroomStudy: Weekend Sleep Helps Blood Pressure
A new study says that sleeping later at the weekend may be good for you. Scientists in South Korea studied about 40,000 adults. The study followed these adults for seven years. People who slept longer at the weekend had high blood pressure less often. The best amount of extra sleep was one hour and 27 minutes.
For years, experts told people to sleep and wake at the same time. But too little sleep makes the heart work harder. Extra sleep at the weekend helps the body rest. However, more than four extra hours is not good.
More than 1.3 billion people have high blood pressure. It can cause a heart attack or a stroke. Doctors say people should not feel guilty about sleeping late. But they must still exercise and eat well.
