We all want to get a good night’s sleep, but in this digital age, it’s becoming more and more difficult. With screens inundating our lives, from laptops to iPads and smartphones, blue light is a constant presence in our lives. But what exactly is blue light, and how does it impact our ability to get sleep? In this blog post, we will explore the science of blue light and its effects on our sleep cycles. We’ll look at how much blue light technology emits, why it affects us the way it does, and what you can do to minimize its impact. So read on for some helpful tips on how to get a good night’s sleep in the digital age!
What is blue light?
Blue light is a type of light that is emitted from electronic screens, such as computers, phones, and TVs. This type of light has a shorter wavelength than other colors of light, and it is believed to affect the body in different ways than other colors of light.
Some studies have shown that blue light can have negative effects on the body, including disrupting the body’s natural sleep cycle. The human body is designed to wake up when exposed to sunlight, and exposure to blue light can trick the body into thinking it is daytime. This can make it difficult to fall asleep at night and can lead to fatigue during the day.
There are some steps you can take to reduce your exposure to blue light, such as avoiding electronics two to three hours before bedtime, or using blue-light blocking glasses. You can also try using apps that filter out blue light from your electronic screens.

How does blue light affect sleep?
Exposure to blue light before bedtime can disrupt your natural circadian rhythm and make it harder to fall asleep. The blue wavelength of light suppresses the production of melatonin, a hormone that helps regulate your sleep-wake cycle.
Too much blue light exposure late at night can also lead to digital eye strain, which can cause fatigue and irritability. Limit your exposure to blue light in the evening by avoiding screens for at least an hour before bedtime. If you must use screens late at night, try wearing blue-light blocking glasses or installing an app that filters out blue light.
The risks of blue light exposure
blue light exposure can disrupt your sleep cycle and cause you to feel more alert at night. It can also affect your mood, energy levels, and ability to concentrate during the day.
How to reduce blue light exposure
It is no secret that blue light exposure can have negative effects on our sleep. But what many people don't know is that there are simple steps we can take to reduce our exposure to blue light and get a better night's sleep.
Here are some tips for reducing your blue light exposure:
1. Avoid using electronic devices in the hours leading up to bedtime. If you must use them, try using blue light filtering glasses or installing an app that reduces the amount of blue light emitted from your device.
2. Use dimming lights in your home in the evening, and avoid using bright overhead lights.
3. Invest in blackout curtains or shades for your bedroom windows to block out any unwanted light.
4. Try not to watch television or work on the computer in the dark – this can actually increase your exposure to blue light. If you must work or watch TV in the evening, consider using a blue light filter on your device or wearing blue light filtering glasses.
5. Consider investing in a quality alarm clock that emits very little blue light, so you can avoid being exposed to bright lights first thing in the morning.
