We all know that going to bed early is good for us. Scientists may have found the healthiest time to go to bed. They say a bedtime of between 10pm and 11pm is best because it lowers the risk of heart disease. Six years ago, the scientists collected data on the sleep patterns of 80,000 volunteers. The researchers collected data on their sleeping and waking times. They then monitored the volunteers' health for six years. Around 3,000 volunteers developed heart problems. They went to bed earlier or later than the "healthy" 10pm to 11pm time.
One of the scientists commented on his research and the effects of sleeping times on our heart. He said the results of his research suggested that going to bed early or late, "may be more likely to disrupt the body clock" and be bad for cardiovascular health. He said it was healthier for our body 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." He added that we risk heart disease if our body clock is not reset properly.
Back to the bedtime lesson.
