Best Night Light Color for Sleep

A lot of people are used to sleeping on the light at night and always choose blue/white color light. Because many of us think that blue/white lights might make us feel relaxed and will help us sleep better.

However, a new study shows that blue light has a great influence on mood, followed by white light. It means that we would not be relaxed or calm before sleeping if the light color is blue/white.



What is the Best Color for Night Light?

Is yellow? Pink? Green? The answer is RED! How unexpected it is!

Based on Hamsters research, red color light is the most conducive to sleep. At night red color light can significantly reduce people’s depressive symptoms compared with blue/white color light.


Why Red Color Light Is the Best for Sleep?

There are some specialized light-sensitive cells called ipRGC's located in the retina of our eyes. Any light can be detected by these cells which is helpful for our brain to regulate the body's clocks. In simple terms, they help to determine when people feel sleepy and awake. These ipRGC cells are most sensitive to blue light wavelengths and least sensitive to red light.

Tips to Choose Night Light

If you don't have a red light, you can use other color light instead, such as light yellow, pink or other color verging to red. Actually total darkness is the best to sleep
