Blue Light and How it Affects Your Body

Sleep can be a controversial topic, especially when you don’t get enough. Some people claim that exhaustion could caused by eating habits or diets, but studies show it mainly comes from screen time and how often you actually look at your phones or computers.

Blue light has been a researched topic for the past few years, as it only came along with technology such as computers and phones. The term blue light actually comes from the colors a screen makes. Different variations of colors are made up of different settings of red, green, and blue pixels that create the images or videos. Blue is the most harmful of the 3 because it can affect your sleep cycle.

The Blue Light Effect noted by SCL Health, “The blue light emitted by your cell phone screen restrains the production of melatonin, the hormone that controls your sleep-wake cycle (aka circadian rhythm). This makes it even more difficult to fall asleep and wake up the next day. The circadian rhythm seems to be especially sensitive to blue light since it has a short wavelength. Studies also show that exposure to blue light can cause damage to your retinas.” These effects can also lead to symptoms such as headaches, nausea, eye-strain, and even vomiting.

This eye strain and fatigue blue light creates can affect your sleep style and ruin your schedule. That is why it is good practice to charge your phone away from yourself when you sleep, and to take the time out of your day to just put down your electronics.
