The Impact of Blue Light on Sleep

Blue light is one of the multiple wavelengths of light that our electronic devices emit. During the day, it's not a problem. In fact, it can help us feel alert and improve our cognitive performance. However, exposure to blue light at night can disrupt our internal biological clock, known as the circadian rhythm.

This circadian rhythm regulates many aspects of our health and well-being, including sleep. When it's disrupted by blue light, it can be harder to fall asleep, and the quality of sleep may decrease.

What can you do about it?

Don't worry, we're not suggesting that you should abandon your electronic devices forever. Here are some tips you can follow to minimize the impact of blue light on your sleep:

Tip #1: Use a blue light filter app

Many electronic devices offer settings that reduce blue light emission, such as Night Shift for iPhone. In addition, there are several apps available that can help you adjust the light emission from your devices.

Tip #2: Apply high intensity light protectors on all screens you use.

Screen protectors, in addition to preventing sleep disorders, help reduce the toxicity that the eyes receive. There are protectors for laptop screens, smartphones, tablets, monitors, and televisions.

Tip #3: Use blue light blocking glasses

If you must use electronic devices at night, consider buying glasses that block blue light. These glasses have special lenses that block or filter blue light.

Tip #4: Turn off your electronic devices before bedtime

The best strategy is to turn off all electronic devices at least an hour before bedtime. This will give your body the chance to prepare for sleep.

Remember, every little change can make a big difference in your sleep health. Take one step at a time, and you'll soon see the results!
