At least 1/4 to 1/3 of a person's life is spent in sleep, because sleep quality is largely related to physical health.
For many young people, lack of sleep has become a common problem, such as not being able to fall asleep after playing with their phones before going to bed.
At present, people eat, work, life are inseparable from mobile phones, and many people are used to lying down before going to bed to play mobile phones, some studies have shown that long-term so easy to affect physical health.
First, cervical spondylosis
When most people play with their mobile phones, maintaining a posture for a long time is likely to harm the cervical spine and lead to cervical spondylosis.
One experiment proved that when people lower their heads more than 45 degrees, it is like hanging two large watermelons around their necks, and the harm to the cervical spine is obvious.
At the same time, it is also necessary to reduce the time to play mobile phones, try not to play mobile phones with your head down, especially the posture of lying down and playing mobile phones at night.
Second, it affects vision
When some people lie down and play with their mobile phones, the vision of the left and right eyes will be affected, because the pressure of the pillow on the eyes leads to a lack of blood supply, and over time, the eyes will have a sense of expansion, which will affect the function of vision.
Third, the eyes are dry, strabismus, and even blindness
Many people in the mobile phone, like to turn off the lights to play mobile phones, long-term in the dark environment staring at the phone, the frequency of blinking will decline, the excretion of tears will be reduced, thus causing great harm to the eyes.
For example, in a short period of time, there will be eye tiredness, blurred vision, dry eye, increased intraocular pressure, dilated pupils, glaucoma, and even blindness.
In particular, playing mobile phones lying on the side will also cause astigmatism in the eyes or large visual errors in the left and right eyes, aggravating myopia or causing strabismus.
Fourth, memory decline
Playing mobile phones for a long time also has great harm to the brain, such as mobile phone radiation, but using mobile phones for a short time will not bring much radiation.
However, if you play with your mobile phone for a long time before going to bed at night, the longer you stare at the mobile phone, the greater the harm to the body, because microwave radiation will directly harm the brain through the skull, resulting in neurasthenia, headaches and memory loss.
The 4 injuries of lying down and playing with mobile phones before going to bed have been clearly understood, and at this time, we need to pay attention to the relevant precautions for playing surgery.

If you want to maintain eye health, do not play with the phone before going to bed, especially do not turn off the lights to see the phone, because in the dark environment, the screen will be particularly bright, which can easily affect the health of the eyes.
If you want to see the phone, you should turn on the light so that there is no obvious contrast between the external environment and the brightness of the screen, thereby reducing the impact of the screen on the eyes.
Second, don't look too long
Many people look at their phones for hours before going to bed, which not only affects people's sleep, but also causes great harm to the eyes.
If you look at the phone for work reasons, it is necessary to put it away after solving the problem, do not open all kinds of applications, and spend energy on it, too long, it will affect the eyes.
