Going to bed late could shorten our life. A study looked at 430,000 adults aged from 38 to 73. Researchers said people who went to bed late were 10 per cent more likely to die earlier. People who sleep late might also have more health problems. People who sleep early and wake up early had fewer health problems.
A researcher said working times should change. People should start and finish work later so they can sleep more. Late sleepers have a higher risk of mental and health problems. They also smoke more, drink more alcohol and take more drugs. Different sleeping patterns at weekends also cause more health problems.
