Sleep when you are tired from playing with your mobile phone?
Wake up, fondle admiringly for smart phones will not help us feel sleepy and promote sleep.
Studies have shown that an imperceptible physiological reaction caused by playing with mobile phones can keep people awake all the time!
Let’s imagine such a scenario:
It’s 1: 00 a.m. This is supposed to be your sleep time, but you are still addicted to mobile phones, watching current affairs news, micro blogs and friends circles.
The result of this is what?
Mobile phones not only help us understand the outside world, but also keep us awake at night.
Why are cell phones [sleep killers]?
If you still remember the contents of the nature class and biology class when you were a child, our eyes can sense light within a certain wavelength range.
Different wavelengths produce different colors, which help us adjust the internal biological clock of the body.
Scientists believe that light is the best biological hint to help us sense time and work and rest, of which blue light can most effectively prompt people to arrive in the morning.
Guess, what has released a lot of blue light?
Your iPad!
Your cell phone!
Your computer!
This means that when we brush news, social platforms or play hand games in bed late at night, the blue light received by our eyes is telling our bodies: it is morning! The sun is coming out!
On the contrary, what our bodies need at night is red light, which means the coming of night. Red light will tell the body that it is night now and we should be ready to sleep.
Light how controls our sleepiness?
Our bodies use optomelanin to obtain signals of diurnal changes. This is a protein sensitive to specific light. When exposed to blue light, it changes its shape and sends out biological signals.
How does optomelanin send signals to the body?
It turns out that it is hidden outside [inner photosensitive retinal ganglion cells]. The number of these cells is very small, usually located deep in the retina behind the eye, and will not affect our vision.
However, the signals collected by these nerve cells through optomelanin are sent to a place in the brain called the suprachiasmatic nucleus (SCN), which is where the biological clock that controls our circadian rhythm is located.
In this way, optomelanin deep in the retina tells our bodies that what should wake up and what should fall asleep. Even if the eyes are closed, light passing through the eyelids will enable optomelanin to successfully send signals to let the brain know the situation at this time [sunrise and sunset].
How can I sleep without looking at my cell phone?
Although we still don’t know much about the occurrence of sleep, we can still understand that the best way to sleep rhythm is to work and rest according to the natural needs of our bodies-eat at the right time and fall asleep when we are tired.
Then we will find that we can get more sleep and rest time.
So, what should I do before going to bed?
Super simple!
Do the right thing at the right time!
When preparing to go to bed, please be sure to turn off the screen of your mobile phone and tablet computer. You may as well read a book on “Sleepy as soon as you open it” to help you sleep.
