1, crossing your legs is also the most common habit. Many people have it, but this habit is not very good, which will hurt the blood circulation system of the feet, especially those with long legs, and it is very easy to get arterial thrombosis. In addition, when crossing one's legs, the working pressure of the upper body is unevenly distributed on the back, which will lead to spinal dislocation for a long time.
2. Pinch your knuckles Whether in movies or in daily life, you will often see some people holding hands and making a "snapping" sound. Although it looks handsome, some people even think that it can theme joints and improve the flexibility of joint operation. But I don't know that this little habit is actually impossible. Joints are often squeezed because there is a liquid like lubricating fluid in the joints. If the liquid is reduced and friction occurs in the middle of the joint, you will hear the sound. Squeezing joints often can lead to joint damage, so you can only play, not often.
3, often dig ears Many people think that earwax is waste and should be removed on time. Actually, it's not. Earwax is not useless and unclean. It is sour and covers the skin surface of the ear canal, which has a certain protective effect on the ear hole. Frequent ear digging will stimulate the skin inside the ear, cause inflammation, and lead to increased metabolism of earwax. If you are not careful when pulling out earwax, it is very easy to scratch your skin and cut the eardrum, which will hurt your hearing.
Squeezing acne by hand is not a good way to solve acne on your face. Many people know it, but I can't help but squeeze my face with acne. If the acne on the face has long been perfect, you can use special technical tools such as acne needle to discharge it through disinfection and sterilization, and reduce the swelling of the wound after extrusion. Hands are untidy, and it is very easy to accumulate germs under nails. If you squeeze acne by hand, it is easy to have feelings, so squeeze acne by hand and resolutely put an end to it.
5, brushing your teeth and gargling for too long can clean your teeth and teeth, which can avoid dental disease and oral inflammation. But brushing your teeth and gargling for too long is not good for your body and mind. Because there is only a thin layer of dental cement from the neck to the gums to maintain the gums, brushing and gargling for too long will damage the gums, causing bleeding and periodontal disease.
6. Sleeping with your head covered Many people like to sleep with your head covered, but that will disrupt everyone's inspiration rhythm. In the process of sleep quality, the oxygen inhaled by everyone and the carbon dioxide in the blood night will be exchanged in the lungs, and then blood night will send the novel oxygen to the internal organs of the human body, so that everything can operate normally and be harmonious with each other, and the spirit will of course be mellow.
When you sleep with your head covered, the supply of oxygen will be limited because of the isolation of the quilt. The oxygen in the bed will decrease with the increase of breathing times, and the carbon dioxide will increase. The blood that is supposed to deliver oxygen carries strong carbon dioxide at night, so human organs can't get enough oxygen and can't operate normally. Of course, listlessness will become what you wake up the next day.
