The one important reason why children should always sleep in the dark
When we sleep, our bodies repair and restore our biological systems. So it's important that nothing disturbs our rest - neither sounds nor excessive light - in the latter case because the hormone melatonin is produced in darkness. And when we have enough of this hormone, we get sick less often and we're generally happier.
We at Bright Side decided it was time to stop going to bed too late, and so we prepared this handy guide for you that explains how important it is to sleep without the light on.
