Sleeping Poorly? Trouble Focusing? Mastering the Yin and Yang of Light Could Ease Your Troubles

Posted on

While it may seem crazy to think the color of your nightlight could impact your health, studies have shown just that to be true. By learning about which tones are most healthy, you can act to protect your natural circadian rhythm, ensuring a good night's sleep and an easier time focusing during the day.

The Harmful Effects of Cool Lighting

Blue-toned and white lights like those given off by electronics and fluorescent bulbs have both proven harmful to humans when left on at nighttime, interrupting circadian rhythms and throwing off natural sleep cycles. The effect isn't only to keep you awake, either. People who are exposed to cool lighting before bed often suffer a lasting dip in mood and can even develop depression from regular use of blue or white nightlights. 

Predictably, warm lighting in the evenings can have the opposite effect, promoting calmness and restfulness. Dimmer lights in red and orange tones are less likely to interfere with your sleep schedule or cause your mood to suffer when used regularly in the evenings.

Cool Light As a Good Thing

But that isn't to say that cool-colored lights are never good to use! On the contrary, all of the traits that make them unhealthy at night can help you during the day. Because they inhibit the release of melatonin in your brain—a chemical that induces drowsiness—you can experience more alertness, faster reaction times, and increased mood as a result of daytime blue-light exposure.

The Best of Both Worlds

Switching from cool to warm lights throughout the day may sound like a hassle if you use traditional fixtures with one-color fluorescent or incandescent light bulbs. Fortunately, those aren't your only options.

In addition to the longevity of their bulbs' lifespans, LED light fixtures can also have the ability to change color when needed, switching between two or more tones at the flick of a switch. That way, you don't have to worry about buying and swapping out multiple bulbs and fixtures in order to enjoy appropriately-colored light morning, noon, and night.

You can also benefit from ensuring your electronic devices go through a daily color shift as well. Some tablets and phones come with a built-in lighting setting, while you may need to download apps for computers and other devices that do not natively have the capability.

The light you're exposed to throughout the day could be having a more serious effect on your health than you realize. If you're conscientious about which shades of light you use at different times, you can make sure that effect is a good one and hopefully net yourself a better night's sleep!
