“I' m going to bed earlier tomorrow!” But no matter how we decide, there are still many chances that we break our promises.
This behavior is called “bedtime procrastination(睡眠拖延症)”, and results from being short of self-control and our body clock.
Bedtime procrastination is a common problem. According to a study, among 2400 people, 53 percent of them couldn' t follow their sleeping time they had planned, delaying it at least twice a week. They delayed bedtime not that they liked to stay up late, but that they couldn' t stop doing some other things.
Accordingly, people who usually have trouble resisting temptations ( 诱惑) and adhering to their intentions are more likely to delay going to bed.
However, scientists think being short of self-control is not the only problem. Our body clock also plays an important role in terms of bedtime.
In order to check the influence of the body clock on sleep, scientists studied the sleep patterns of 108 people. It was found that those who got up late were more likely to delay their bedtime than those who woke up early every morning.
And more surprisingly, night owls(夜猫子) would go to bed late at the very beginning of the weekday, even though they had to get up early for work or school. It's their special body clock that plays a part in delaying their bedtime.
People always think that bedtime procrastination isn't a big problem, but the choices we make that affect our sleep could finally be pretty important for our health.
