First of all, lying down and using a mobile phone will have a bad effect on your eyesight. Because mobile phones are usually below the eyes, people tend to subconsciously squint their eyes in order to see the contents on the screen more clearly. This posture can lead to eye muscle fatigue and myopia. In addition, staring at the mobile phone screen for a long time will make the eyes dry, leading to eye problems such as dry eye.

Secondly, lying down and using a mobile phone will also affect the posture and blood circulation of the body. When people use mobile phones in bed, they tend to curl up, which will put pressure on the cervical spine and back, causing pain and discomfort. At the same time, maintaining this posture for a long time will also affect blood circulation and increase the risk of thrombosis.

Therefore, the correct posture of using the mobile phone should be to keep the body straight and keep the mobile phone at a certain distance from the eyes to avoid continuous use for a long time. You can use a bracket or other tools to place the phone at a suitable height and angle to reduce the pressure on your eyes and neck. In addition, regular eye rest and stretching exercise also help to relieve eye and body fatigue.

In a word, it is very important to use the posture of mobile phone correctly to protect your eyesight and health. We should avoid using mobile phones while lying down, but adopt proper posture to reduce unnecessary stress and fatigue.
