Even after sleeping, the skin can perceive the color of the quilt, red makes people anxious, blue, white makes people calm.
But is it really the case?
Color does affect sleep quality
The first conclusion is that the color of the quilt and the color of the bedroom wall will indeed affect the speed and quality of sleep of some people to a certain extent, but it is not because the skin can perceive color.
In the large number of insomnia cases received, the impact of environmental factors on sleep is often ignored, and psychological factors are often exaggerated. In fact, many insomnia symptoms can be started by improving the sleeping environment.
The influence of environmental factors on sleep is mainly reflected in light, sound, temperature, humidity and touch, etc. The color of quilt and bedroom wall is to affect people's sleep through light.
The reason is that the retina of the human eye has a special light-sensitive cell called ganglion cells, which are most sensitive to blue.
Ganglion cells in the retina send blue messages to the part of the brain that controls the body's 24-hour rhythm, which affects sleep and how you feel the next day. Overall, blue is associated with feelings of calm and helps lower blood pressure and heart rate, all of which help you get a good night's sleep.
However, photoreceptor cells are objective, but everyone's preference for color is subjective, and blue makes people calm is based on the mainstream results of observation and statistics, and does not apply to everyone.
If you're a different kind of firework and blue isn't your thing, consider switching to a cooler neutral color, such as gray or silver, to improve your sleep. If you prefer something brighter, consider a pale yellow. In short, choose whichever color makes you feel calm and comfortable.
So, if you feel depressed and nervous when you lie in bed recently, you can try to change a quilt cover in your favorite color, or change a batch of wallpaper for the bedroom.
Note that the likes here are the feelings that make you "comfortable" and "calm", rather than the colors that make you "excited" and "enthusiastic".
Skin doesn't perceive color
As for the human skin can perceive color during sleep, it is a theory taken for granted by funny bloggers, not a serious scientific study.
There is an animal in nature that can sense color through its skin, and it's not a chameleon, as many people think, but a cephalopod octopus.
The study found that "chromatophores" in octopus skin can directly respond to light, and sensory nerve cells in their skin produce opsin proteins needed to detect light, and these opsin proteins allow octopus to detect different wavelengths of light.
However, there are no opsin structures in human skin at all, and no high-quality studies have observed that human skin can perceive color.
After sleep, the colors of the world exist only in dreams.
The formula to improve sleep
Of course, it takes more than color to sleep better.
Most importantly, you need to know why you're not sleeping well. I share with you a very useful formula, all the secrets of sleep problems can be expressed in this formula:
Motivation + rhythm - resistance = sleep
In other words, if you have sleep problems, you can first find reasons from these three aspects.
