Do you have a sleep problem? 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 News. 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. They also fell asleep more quickly at night.
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. 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 15 minutes of sunlight in the morning.
