阅读下面短文，根据其内容写一篇60词左右的内容概要。

Are you sick of going to bed late and waking up tired? Then grab your hiking boots and a tent. A new study suggests that a couple days of camping in the great outdoors can reset your circadian (昼夜节律的)clock and help you get more sleep.

The circadian clock, more commonly known as the body clock, is an internal system that tells our bodies when it's time to go to sleep and when it's time to wake up. Scientists track this clock by measuring the amount of melatonin(褪黑激素)circulating in a person’s blood at any given time. In a healthy sleeper, melatonin levels rise a few hours before bedtime, stay high through the night, and then settle back down when it's time to wake up.

In our modern society, however, most of us stay up many hours past sunset and would probably sleep in many hours after sunrise if we could. And the trouble is that your melatonin levels may still be high when your alarm clock goes off in the morning, which leads to grogginess(头晕眼花). It may also have other health consequences as well, such as diabetes(糖尿病), overweight problems and heart disease

Professor Kenneth P. Wright of the University of Colorado in the US wanted to see if our body clocks can be reset by a short stay in nature. His team recruited (招收)14 physically active volunteers in their 20s and 30s. Nine went on a weekend camping trip, while the other five stayed home. At the end of the weekend, the researchers reported that in just two days, the campers' body clocks had shifted so that their melatonin levels began to rise more than an hour earlier than they did before they left on the trip. By contrast, the body clocks of the group that stayed home shifted even later over the course of the weekend. ''This tells us we can reset our clocks fast, '' Wright said.

Therefore, if you want to change your sleep patterns you could try to increase your exposure to natural light during the day and decrease the amount of artificial light you see at night.
