Blue Light: 4 Reasons Why It Is Useful

Blue light is one of the reasons why life on Earth exists. It has many uses, but it can also be harmful to our health if we are not careful with how much blue light we are exposed to. In this article, you will learn about four reasons why blue light is useful.

It Helps You Stay Alert

When you’re on a schedule, doing a project, or anything else that requires concentration, blue light can help you stay alert. Even though it’s smart to get protected from it, long term use of these glasses can actually prevent the positive effects this light has. When coming from the Sun, blue light is the most useful, since this type of light comes from a natural source. During waking hours when you need your brain to be in top form, it’s important to have access to all types of lighting including ultraviolet and infrared.

It Helps Your Alertness And Reflexes

Blue light is the most useful in the early morning and during twilight when you’re getting ready for bed. Exposure to this type of lighting helps your brain prevent melatonin production, which means it will be easier for you to stay alert throughout the day. As a result, blue light has been shown to improve leg muscle strength, helping reflexes too!

This means you’ll function much better during the day thanks to blue light because it’s what helps your brain stay alert. That being said, it can also help to improve sleep quality when you’re in the evening or at night time because melatonin production is delayed with this type of lighting.

It Helps You Read Faster

Since it’s helping with alertness and concentration, blue light also helps people to read faster. Whether you read for pleasure or as a job, being able to work at top speed is often necessary and useful in many situations. It’s also been found that blue light can improve focus during reading sessions by helping people avoid distractions from their surroundings.

You’ll go through any book faster when you can focus better. It will also allow you to remember more from what you read. That is an important feature especially when you’re reading something for school or self-improvement. You’ll remember way more on the first read and be aware of everything the second time you’re going through.

It Impacts Your Mood Positively

Blue light is known to help people with depression and overall boosts mood. In the evening, blue light is especially helpful in giving you a sense of happiness and well-being. The body will release endorphins when exposed to this type of light which helps improve your overall emotions.

It’s also known to help a lot with seasonal affective disorder. This type of depression is caused by the lack of sunlight in winter which affects people’s moods negatively. Blue light helps with this issue because it will trick your brain into thinking you are getting more sun exposure than what actually exists, helping improve one’s overall outlook on life and emotions.

Here are the things blue light helps with when it comes to mood:

  • boosts mood (in the evening)
  • helps with seasonal affective disorder
  • releases endorphins in the body when exposed to it
  • helps improve the overall outlook on life and emotions
  • reduces anxiety levels
  • improves sleep quality
  • helps with depression
  • increases concentration levels which is helpful for those who work in shifts or long hours.

Note that it’s important your exposure to this is natural and not from a screen. In the evening, it’s best to avoid blue light exposure because this is when your body should be winding down for sleep and not stimulating itself with artificial light. This type of exposure can also lead to insomnia in some cases which will only make one feel worse about themselves in general.

It Helps With Sleep If Used Right

If you’re exposed to natural blue light, it can treat several sleep disorders.  Blue light helps to keep your body awake, but if you are exposed to too much blue light at night it can disturb your circadian rhythm and make it difficult for you to fall asleep. Using a screen right before bed is fine as long as the amount of blue light exposure is not overwhelming.

However, if you get enough blue light from the Sun during the day it can help you with sleep disorders that interfere with falling asleep at night. In fact, blue light therapy has been shown to improve sleep and reduce the time it takes for adults to fall asleep by increasing the secretion of melatonin.

Blue light can be healthy and useful when you’re using it right. It’ll help you stay alert and concentrated, thus making it possible to read faster and better. Apart from that, it’s very important for your mood and it helps treat multiple mental health problems like depression and seasonal affective disorder. Finally, if you get enough sun exposure during the day, it will help you sleep way better at night!
