一、阅读短文,选择正确答案
We may have a bad night of sleep and that's very normal. Do you have a sleeping problem? If you do, now there is a simple way to help you improve your sleep. According to a new study, you may need to see more sunlight, especially in the morning.
A group of researchers from the US did a research on 109 office workers of the country. They found that some of the workers saw lots of sunlight during the morning hours, between 8 a. m. and lunchtime. The result showed that these workers had a better sleep than other workers. They also fell asleep more quickly at night.
Why is sunlight so important to our sleep? Researchers say it helps us set our “body clock”. When there is less and less sunlight at the end of the day, our body starts to make melatonin (褪黑素). Melatonin is a hormone (荷尔蒙), and it makes us feel sleepy so that we know its nighttime and it's time to go to bed. Our body makes the most melatonin at night. But during the day, sunlight tells our body to make less melatonin so that we can stay awake and do our work.
Researchers say that we should see 15 minutes of sunlight in the morning. It can help balance the melatonin in our bodies and give us a better sleep.
