We all know that going to bed early is healthy. Scientists say the healthiest time to go to bed is between 10pm and 11pm. This is because it lowers the risk of heart disease. Six years ago, the scientists looked at the sleep patterns and sleeping and waking times of 80,000 people. They then monitored the people's health for six years. Around 3,000 people developed heart problems. They went to bed earlier than 10pm or later than 11pm.
One of the scientists commented on how sleeping times affect our heart. He said going to bed early or late, "may be more likely to disrupt the body clock" and be bad for our heart's health. He said our body liked to wake up to the morning light. He said: "The riskiest time [to go to bed] was after midnight because it may reduce the likelihood of seeing morning light, which resets the body clock."
Back to the bedtime lesson.
