Why blue light before bed is wrecking your sleep
If you’re one of those people who find it difficult to fall asleep at night, there’s a good chance that blue light might be to blame. Blue light is emitted by electronic screens and can have a number of negative effects on your sleep, including making it harder to fall asleep in the first place.
So what exactly is blue light, and why is it so bad for your sleep? Read on to find out.
What is blue light?
Blue light is a type of visible light that has a shorter wavelength than other colors of light. It’s also known as high-energy visible (HEV) light.
While blue light isn’t necessarily harmful during the day, exposure to it at night can disrupt your sleep. That’s because blue light suppresses the production of melatonin, a hormone that helps you sleep.
How does blue light affect sleep?
Exposure to blue light at night can cause a number of different problems with sleep. For one thing, it can make it harder to fall asleep in the first place. That’s because blue light suppresses the production of melatonin, which makes you feel sleepy.
But even if you’re able to fall asleep, blue light can still have a negative impact on the quality of your sleep. Research has shown that exposure to blue light at night can reduce the amount of time you spend in deep sleep. Deep sleep is important for feeling rested and refreshed when you wake up in the morning.
So if you’re regularly exposed to blue light at night, you might find yourself feeling tired and groggy during the day. You might also be more likely to suffer from conditions like insomnia or sleep deprivation.
What are some sources of blue light?
There are a number of different sources of blue light, both natural and artificial.
Natural sources of blue light include the sun, fire, and water. Artificial sources of blue light include electronic screens, such as televisions, computers, and smartphones.
What are some ways to reduce exposure to blue light at night?
If you’re looking to reduce your exposure to blue light at night, there are a few different things you can do.
One option is to avoid using electronic screens for at least an hour before bed. This includes turning off your television, computer, and smartphone. If you must use electronic screens at night, consider wearing blue-light blocking glasses.
Another option is to install software that filters out blue light on your electronic devices. For example, the f.lux software can be installed on computers and smartphones to reduce blue-light exposure.
You can also change the settings on your electronic devices so that they emit less blue light. For example, most smartphones have a “night shift” or “night mode” setting that can be enabled to reduce blue-light exposure.
Finally, you can try using a red light bulb in your bedroom at night. Red light doesn’t have the same effect on melatonin as blue light, so it won’t disrupt your sleep.
