If you play the cell phone at night, you may increase the number of times you stay up late, which is not good for the development of the pregnant woman and the fetus. Long time looking at the cell phone will also affect the pregnant woman’s eyes, causing eye fatigue, dryness and pain, leading to vision loss. Pregnant women who play with cell phones for a long time will keep their heads down or sit and stand for a long time, and a posture for a long time can easily cause cervical spondylosis and lumbar spondylosis.
