問題詳情：
It is rare to find someone who jumps out of bed fully awake as soon as his or her alarm clock goes off in the morning. According to a survey of people in England, the average adults there do not feel fully awake until 9:55 am. Of course these survey results do not apply to everyone. When it comes to what affects our sleeping habits and what happens in our body while we sleep, scientists have found two systems that adjust people’s sleep and also decide how difficult it is for a person to wake up from sleep.
Our system for adjusting sleep is like a clock inside our body. This body clock makes us feel sleepy or awake at certain time each day. Age can also affect the time set by our body clock to make us sleepy or awake. Most people go through a sleep phase delay when they are teenagers. During this phase, teenagers feel naturally more awake later at night. Thus, it might be difficult for a teenager to fall asleep before 11:00 pm. Since teenagers typically have to wake up early for school, it becomes difficult for them to get through sleep each night. On the other hand, those who do get enough sleep at night will feel less sleepy in the middle of the day when the clock in their body signals a peak sleepy time.
In addition to the “sleep clock” in our body, there is also a “sleep meter” in each of us. The sleep meter keeps track of how much sleep we get each night. This meter also helps our body stay asleep throughout the night in order to balance the hours when we are awake during the day. So the sleep meter is like a natural device in our body that helps us balance the amount of sleep we need with the amount of time when we are awake each day. Some people seem to have a meter that tells them they need less sleep each day than others. Thus, while health professionals recommend 8-10 hours of sleep for children to have a healthy lifestyle, some people can be healthy with a bit less sleep.
