More than most of us realize, light plays a significant role in your sleep cycle. One fascinating finding from studies is that light may not be the only factor influencing our circadian rhythms; the hue of the light may also play a role.
If you have to sleep with a night light on, you might question if the hue of the smart LED light is troubling your sleep. Actually, if you have white or blue lights in your bedroom, you should exercise caution and think twice. According to a new study, blue light had the greatest impact on mood, followed by white light.
If the light color is blue or white, If the light color is blue or white, one may not feel peaceful or calm before sleeping. So, what is the best LED color for sleep?
How Light Affects a Person's Sleep
The effect of light on sleep is a complex and important subject. Especially for individuals with sleep disorders, pregnant women, and children, it's important to consider these aspects in bedroom decor. The following briefly describes some effects of light on sleep, which I hope will be helpful to you.
1. Natural light and circadian rhythm
Natural light, especially morning sunlight, helps regulate our biological clock. It helps us wake up and stay awake by affecting the production of melatonin.
And our bodies have an internal circadian rhythm that is influenced by natural light. When the light is dimmed, the body secretes melatonin, which promotes sleepiness; when the light is brightened, melatonin secretion decreases and we feel awake.
2. Artificial light
Blue light like that emitted by electronic devices (e.g. cell phones, computers, TVs) can inhibit the secretion of melatonin, delaying sleep onset and affecting sleep quality. Prolonged exposure to blue light may lead to sleep disorders.
Therefore, exposure to too much light before bedtime can disrupt the biological clock, affecting the speed and depth of sleep. Softer lighting helps to relax and prepare for sleep.
3. Light color
Cool-colored light such as blue and white light is usually used for daytime activities and helps improve concentration and productivity. However, at night, cold-colored light may disrupt sleep. Warm colors of light, such as red and orange, are more suitable for nighttime use because they have less effect on melatonin, helping to relax and promote sleep.
How Does Light Color Help You with Sleep?
When you are exposed to bright, somewhat blue light, such as that from your smartphone or television, your body sends a signal to your brain to cease producing melatonin, a powerful hormone that aids sleep.
The normal synchronous relationships between sleep and daytime activity and cortisol, melatonin and body temperature.
Unfortunately, waking up in the middle of the night, either because of a kid or because our bodies can’t seem to relax, is an all-too-common experience for many of us, and the repercussions may have a lasting impact on the rest of the day.
When many individuals have problems getting back to sleep, they make the same mistake: they turn on a bright light bulb in the middle of the night.
For a long time, we’ve known that blue light may disrupt our bodies’ internal clocks. Light-emitting e-readers have been found to disrupt our sleep by inhibiting melatonin production in our bodies and increasing alertness.
So, Which Color LED light is Best for Bedroom
Red light has a lower color temperature than typical sunlight, making it ideal for sleeping. Red light may be used at night without jolting your body or disrupting your internal clock, as blue light does.
If you're having difficulties sleeping and are frequently exposed to artificial blue light, this is likely a contributing factor. In the evenings, switching to natural red hue might assist your body in transitioning more smoothly into its sleep cycle.
