Why watching TV at night keeps you late (and how to fix it)



The screen on your TV (and other devices like tablets and phones) radiates blue light, and when you look at it in the dark, it can cause problems.

Some believe that this blue light can damage your eyes . A study by the University of Toledo found that blue light triggers the creation of toxic molecules in the retina of photoreceptor cells. These molecules can accelerate vision degeneration.

While more research needs to be done on the harmful effects of blue light on the eyes, it is agreed that this type of light affects your sleep because your body perceives it as daylight. Nighttime TV can disrupt your body's natural circadian rhythm by reducing the amount of melatonin produced because your body thinks it's daytime. Melatonin is basically a sleep hormone and without that you stay awake.

Use a blue light filter

Many new TVs have blue light filters that you can turn on. The filter adjusts the tone of light from the screen to a warmer tone, which is better for your eyes and chemical production for sleep in your brain.

To start the filter, go to the Settings menu and select Display option . Then search for the blue light filter to activate it. If you do not find the setting, you may want to refer to your user manual.

If your TV doesn't have a blue light option, don't worry. You can buy blue light filters that hold onto the screen that changes the color of the light or blocks the blue light.

Using a Projector

Replacing your TV with a projector can be a good idea. A projector bounces off the light of a wall or screen while a TV directs the light directly to you. So, projectors expose your eyes to less blue light.

Wear glasses

While the jury is still out, blue light-blowing glass can also help. They absorb blue light so that it does not reach your eyes, and all you have to do is release them before turning on the TV. Here's what you need to know about these glasses .
