Do you have a sleep problem? If you do, here is a simple way to help you improve your sleep. You may need to see more sunlight, especially in the morning, according to a study.
A team of researchers from New York, US did the study, reported Yahoo Nows. The team did a study on 109 office workers across the US. Some of the workers saw lots of light during the morning hours, between 8 a. m. and lunchtime. The researchers found 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). It makes us feel sleepy so that we know 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 suggest that we should see fifteen minutes of sunlight in the morning. It can help balance the melatonin in our bodies.
As we all know, with the development of technology, smartphones have influenced the old people in our family a lot. A TV programme interviewed three teenagers on how smartphones influence their family.
My grandfather asked me to teach him how to play the popular video game King of Glory(王者荣耀). I was surprised that he was interested in this! He chats with family members on Wechat every day. He tries to learn other new things as well. For example, he watches courses on learning apps. Although he is old, he still cares about technology and sports. So, as we can see, the Internet can help elderly people. —Xing Yuxi, 12, Chongqing |
I live in Hangzhou, a city of technology. People enjoy the convenience(便利) brought by the Internet. However, I often worry about the elderly. Take my grandma as an example. On one hand, she would like to get discounts by using mobile phones. On the other hand, she's afraid of getting cheated online. I think it takes time for elderly people to get used to these things. We should help them keep up with the times. — Sun Run, 14, Zhejiang |
Smartphones have made a big difference in my grandma's life. In the past, newspaper and TV programs were her only ways to get information. However, it was not good for her eyes, as she has severe cataracts(严重白内障). But now, she can listen to the news through all kinds of apps on her mobile phone. She doesn't have to look at the screen all the time. Sometimes, she even plays mobile games for fun. Thanks to the Internet, my grandma now has a more colorful life. —Wen Jiayi, 13, Sichuan |
