What Exactly is Blue Lights? According to studies, Blue Light is a color in the visible light spectrum that can be seen by our eyes. It is basically everywhere, from the light of the sun to artificial sources, like, fluorescent lights, Light Emitting Diodes (LED), computer screens, our smartphones, and many more. How does it disrupt our sleep? Blue Light suppresses the production of melatonin in our body, it is a hormone that makes us feel sleepy, which can cause us to lose sleep. Exposure to Blue Light during the daytime is a healthy agent for our body for it promotes energy. On the other hand, exposure to artificial sources of Blue Lights at night interrupts our usual routine by tricking our brain into not releasing said melatonin, which results and ends up in us not feeling tired. This is one of the main reasons why using phones before bedtime is not a good idea if you want to have a good sleep. How can we lessen our exposure to Blue Lights at night? There are many things to do to minimize exposure. Here are some of the tips we recommend: a.) Set a reminder or alarm 2 hours before going to sleep, so your body and brain can rest and produce melatonin. b.) Read a book. Make reading before bedtime with the proper amount of light an alternative before going to sleep instead of using your phone all the time. c.)
