As a child, you might remember hearing “lights out” as a way to tell you it was time to go to bed. Having the lights off at bedtime is much more than a common bedtime phrase, though. In fact, the decision to turn out the lights — or leave them on — could affect your health.

Yet the problem lies beyond ceiling lights and lamps. Light surrounds us from multiple sources, including streetlamps, televisions, and the blue light emitted from our electronic devices, like cellphones, computers, and tablets.

Sleeping with any lights on is considered detrimental to getting a good night’s rest. Subsequently, not getting enough quality sleep can lead to numerous health consequences. If you’re considering leaving a light on at bedtime, consider the following repercussions.

I always stay calm, know how to balance my life. In the eyes of my friends, I am a kind person, caring for others and truly loyal. You are easygoing and reliable. However, I was too sensitive like when I was sleeping on my side.

I'm passionate about a lot of things, including sleeping well. However, I tend to think a lot for myself. Even the bed, I want to own it all. I like comfort, convenience, not over anything.
