<正>If you have trouble sleeping at certain times of the month,it could be because of a full moon.Scientists from the University of Washington say there is a link between the lunar cycle and sleeping patterns.They say that on nights when there is a full moon,people could experience more restless sleep.The reason for this could be the Moon’s changing brightness.When there is a full moon,the extra brightness in the night sky could interrupt our sleep.The scientists said,"Moonlight is so bright to the human eye that it is entirely reasonable to imagine that,in the absence of other sources of light,this source of nocturnal1 light could have had a role in changing human nocturnal activity and sleep."
