First, playing mahjong often means bowing your head for a long time, which will easily increase the burden on the spine, cause cervical spondylosis, lumbar disc herniation, and even lead to disability in severe cases. If you get cervical spondylosis, you will feel dizzy and black when you press the blood vessels in the vertebral base. If you get lumbar disc herniation, it will cause sciatic nerve compression and low back pain. Some people have low back pain and can't stand straight. If it is serious, they will have to undergo surgery.
Second, playing mahjong for a long time is to keep a posture motionless for a long time, and the spirit is highly nervous, which is easy to cause poor blood circulation and cardiovascular and cerebrovascular diseases such as hypertension, heart disease, cerebral thrombosis and cerebral hemorrhage. Some people have a sudden stroke when playing mahjong, they can't talk, their mouths are crooked and their eyes are slanting, and some people have a heart attack or even sudden death when playing mahjong. These situations are actually very common.
Third, playing mahjong often will cause unhealthy mood. Playing mahjong once in a while can make you happy. If you play mahjong for a long time, you will become addicted. At this time, you will be restless and anxious, and your personality will become no longer gentle. When you are addicted, if you don't play mahjong for a day, you will fidget and can't do anything.
Playing mahjong often is a sign of mental emptiness. Don't let playing mahjong corrode our bodies. We make our own decisions about our bodies.
