Blue light, a wavelength of light often emitted by electronic devices and artificial lights, can have a significant impact on your sleep. Exposure to blue light at night can disrupt your body's natural sleep-wake cycle, tricking your brain into thinking it's daytime and inhibiting the production of melatonin, a hormone that promotes sleepiness. This can lead to insomnia and other sleep disorders. To improve your sleep, it is important to limit your exposure to blue light before bedtime. This can be achieved by turning off electronic devices, using blue light-blocking glasses or apps, and opting for red or amber-tinted lighting, which has less impact on your circadian rhythm.

What You'll Learn
Avoid screens before bed
The blue light emitted by electronic devices and artificial lights can negatively impact your sleep. Blue light stimulates parts of the brain that make you feel alert and active, which is beneficial during the day, but not so much at night. Blue light can slow down or stop the body's release of melatonin, the hormone that regulates sleep.
To avoid screens before bed, you can start by turning off your smartphone, TV, and other electronic devices a few hours before bedtime. If you need to use your devices, you can try dimming the brightness on your screens or enabling night mode or dark mode, which changes the background from white to black. You can also install blue light-filtering apps on your smartphone, tablet, or computer, which filter out blue light without reducing screen visibility.
If you need to wear glasses, blue-light-blocking glasses with amber or brown-tinted lenses can be effective in reducing blue light exposure. These have been shown to improve sleep quality and mood, although some studies suggest there is a lack of evidence supporting their use.
In addition to reducing screen time, you can also swap out your lightbulbs. LED lights and fluorescent light bulbs produce more blue light than traditional incandescent bulbs. Using a dim red light bulb as a night light can help, as red light has the least impact on your body's circadian rhythm.

Use blue light-blocking glasses
Blue light-blocking glasses are an effective way to reduce exposure to blue light and improve sleep quality. Blue light, emitted by electronic devices and artificial lighting, can disrupt the body's natural sleep cycles and impact health. By wearing blue light-blocking glasses, you can filter out this harmful light and protect your eyes and overall wellbeing.
Blue light-blocking glasses are designed with lenses that filter blue light and reduce glare. They are available in both prescription and non-prescription options, making them accessible to anyone. These glasses can be worn during the day when using electronic devices or at night to block artificial blue light. Wearing them for 1-3 hours before sleep can increase melatonin levels and optimise sleep quality.
When choosing blue light-blocking glasses, look for those that utilise advanced technology to absorb high-energy blue light effectively. For example, the American HEV-Adsorb substrate absorption technology ensures that blue light is blocked while allowing all other beneficial light to pass through. This way, you can maintain high light transmittance and clear vision without sacrificing protection.
Additionally, consider the style and comfort of the glasses. Some brands offer lightweight frames that are both stylish and functional, so you don't have to compromise your unique sense of fashion for the sake of eye health. You can find a range of options online, including those with amber or brown-tinted lenses, which are particularly effective at blocking blue light.
By incorporating blue light-blocking glasses into your daily routine, you can reduce eye strain, prevent headaches, and improve your overall sleep quality. They are a simple yet powerful tool to combat the negative impacts of blue light exposure and promote a healthier and more restful sleep.

Install blue light-filtering apps
Blue light emitted by electronic devices and artificial lights can negatively impact your sleep. It can slow or stop the release of melatonin, the hormone that regulates sleep. To counter this, you can install blue light-filtering apps on your devices.
There are several blue light-filtering apps available for download. For MacOS users, there is an application called Blue Light Filter available on the App Store. This app is designed to reduce eye strain by minimizing the blue light emitted from your screen. It enhances visual comfort, promotes better sleep quality, and protects your eyes from prolonged screen exposure. The basic filter can be used for free, but the app also contains paid functions.
For Android users, there is a Blue Light Filter app available on Google Play. This app reduces blue light by adjusting the screen to a natural color. It also includes features such as adjustable filter intensity, a built-in screen dimmer, and power-saving capabilities. The app is easy to use, with handy buttons and an auto-timer.
Another popular option for Android users is the Twilight app, which is also available on Google Play. This app makes your device screen adapt to the time of day by filtering the blue light emitted after sunset. It protects your eyes with a soft and pleasant red filter. Twilight has been praised for its effectiveness in reducing eye strain and improving sleep. It also offers AMOLED screen protection and can increase the lifetime of your screen.
By installing and utilizing these blue light-filtering apps, you can minimize your exposure to blue light from electronic devices, thereby improving your sleep quality and overall eye health.

Use red night lights
Using red night lights is a great way to improve your sleep quality. Red light has the lowest energy of all colours of light, and its longer wavelengths stimulate the production of melatonin, the hormone that regulates your sleep. This helps your body prepare for sleep and improves your overall sleep quality.
Red light is also easier on the eyes than blue light. The glare from bright white or blue light can cause you to squint and strain, whereas red light is non-glaring and helps you see better at night. This is why red lights are used in airplane cockpits and submarines, and why astronomers and stargazers carry red flashlights.
Using red night lights is especially useful if you have children who are afraid of the dark, or if you need to get up at night. Leaving on a small red light will help you see without ruining your sleep.
You can buy red night lights with built-in LEDs that promote melatonin production and healthy sleep. These often have an auto-on/off function, which makes them even more convenient. However, some people find them uncomfortably bright for use as a night light while sleeping, so it's best to place them out of sight or in areas where they won't shine directly into your eyes.
While red light is a better option than blue light, it's important to remember that the healthiest way to sleep is in complete darkness. This is because, in nature, there is no light after sunset, and we've evolved to sleep when it's dark. So, while red light can be a helpful tool, it's best to switch off all lights when you're ready to sleep.

Get sunlight during the day
Sunlight is an essential part of regulating your body's internal "clock", which helps your body know when it's time to sleep and wake up. This is known as your circadian rhythm. Without regular exposure to sunlight, your body has fewer cues for when to go to bed.
Sunlight is especially important in the morning, as it helps your body understand it's time to be alert and awake. Getting sunlight first thing in the morning helps your body release cortisol, the "wake-up" hormone, and signals the start of a new day. Morning sunlight also starts your body's timer for the onset of melatonin, the "go-to-sleep" hormone, later that night.
To get the best results, try to go outside as soon as you wake up. If you can, go outside within the first hour of waking up and stay outside for at least 30 minutes. If you can't get outside in the morning, try to get at least 15 minutes of direct natural light during the day.
If you're uncomfortable exposing your body to sunlight during the middle of the day or have been advised not to by a health professional, that's fine. You can still benefit from morning and evening light. However, moderate doses of afternoon sunlight can be excellent for regulating sleep. It can help promote alertness, signal to your body that it's daytime, and give your mood a boost.
If you can't get outside during the day, there are other ways to get light therapy. You can buy special lamps to do light therapy inside, or use a "dawn simulator" lamp, which can deliver about 10,000 lux of bright light.
