It is said that Sichuan people love playing mahjong Let me dispel a rumor here How is it possible to play mahjong all the time? We sometimes work The Ten Virtues of Mahjong Players ▽ Honesty: We are really short of one person, and we are waiting for you Brave: I'll just type this, just click it Careful: Wait a minute, I'll sort out the cards. Confidence: This is a self-touch Haoxue: Can you help me see if this is masturbation? Enthusiastic: What do you think of this card? Bet 10,000 and listen to me. Tolerance: I have tolerated you for a long time. Optimistic: It’s okay, I lost more without playing Dafang: Save a year just to be a spendthrift at the poker table Independence: Wrong? I was playing mahjong and died. It’s the end of the year and everyone is looking forward to the event the most. Image source: Publish If you want to be good at playing cards, you need strong mental arithmetic and logical skills, as well as the calculations of which player has doubled the bet and who has fired the cannon. Every hand has to be settled within a few seconds. Image source: Publish It also requires "physical strength". Incorrect sitting posture and long-term sitting can easily lead to back pain. The physical discomfort at this time will more or less affect the desire to win and mahjong skills. Image source: Publish Some friends usually complain of pain here and there every day, but once they sit at the mahjong table, they don’t complain about the hardship or tiredness, and won’t back off even if their waists are broken. [Doctor from West China] I tell you not to sit for long periods of time, just play mahjong for 3 to 4 hours , your mouth will be sore from saying this... I'm sure many people won't listen. Those who read this article today are in luck. [West China Doctor] will teach you the "correct posture" for playing mahjong! Teach you how to sit without pain and how to sit more healthily! Tables and chairs should be paired Our spine has an S-shaped physiological curvature: the cervical and lumbar vertebrae bend forward, while the thoracic and sacral vertebrae bend backward. Image source: Photo Network Adjust the appropriate height of tables and chairs. In principle, the head, neck, chest and lumbar spine should maintain normal physiological curves, avoiding excessive backward or forward leaning of the head and neck and excessive bending of the back . Keep your thighs parallel to the floor and your feet flat on the floor. It is best not to sit on a bench that is too low for a long time, especially for patients with lumbar disc herniation. Try to choose a chair with a backrest , because the backrest can bear part of the weight of the body, so that the abdominal and back muscles are in a relatively relaxed state, reducing the possibility of back strain. If necessary, you can put a cushion behind the waist . Choose a cushion with a slightly harder material and a certain support strength, so that the waist can feel supported. Sit in the right position The correct sitting posture should be to keep your body muscles relaxed and not tense. Don't stretch your neck to read the cards, and don't slump in the chair lazily. A good sitting posture allows muscles to relax without soreness. The following points should be remembered: Sit upright, keep your neck straight, do not lower your head, and keep your head slightly tilted forward; · Your forearms should be supported on the table, and your shoulders should be relaxed as much as possible, instead of being tense all the time; Keep your back straight and your muscles naturally relaxed and not tense; Keep your thighs flat and your feet flat on the ground, don’t cross your legs; Keep your knees slightly higher than your hips, move your hips back, and lean your body lightly against the back of a chair or cushion, keeping the angle between your upper body and legs at about 135 degrees. Finally, I would like to remind everyone that even if you sit upright with perfect posture, you still need to change your posture every once in a while to relieve the pressure on our muscles and the load on our lumbar spine. Image source: Publish In addition to the appropriate table and chair height and correct sitting posture, how can you sit more healthily? The answer is - do some "little tricks" on and under the card table. Not the following! Image source: Publish But these actions: Turn your neck and do the "M" exercise Image source: taken by myself Without moving your shoulders, slowly turn your head left and right until you feel a slight stretch. Hold for 5 seconds and repeat 10 times. Slowly tilt your head toward your left shoulder, bringing your left ear close to your left shoulder, hold for 5 seconds, and repeat 10 times. Then, slowly tilt your head toward your right shoulder, bringing your right ear close to your right shoulder, hold for 5 seconds, and repeat 10 times. Finally, slowly stretch your head forward until you feel a slight stretch, hold for 5 seconds, then slowly tilt your head back, also hold for 5 seconds, repeat 10 times. During the entire process, pay attention to the amount and intensity of neck movement at all times. Keep it comfortable and never forcefully flex, extend or twist your neck. Shoulder exercise Image source: taken by myself Slowly raise your arms above your head, keep your hands above your head for a while, feel the contraction of your shoulders, stay for a few seconds and then lower them, repeat several times. Stretch your arms straight back and feel your shoulder blades retracting backwards. Hold for a few seconds and repeat several times. Put your fingers on your shoulders, use your shoulders as the center of the circle, and circle your shoulders with your arms to feel the movement, expansion, and stretching of your shoulder joints and shoulder blades. You can circle forward 4 times and backward 4 times. Make fists and start making circles with your arms forward. You can circle forward 4 times and backward 4 times. Stand on tiptoes If you feel soreness in your lower limbs after sitting for a long time, you can stand up and tiptoe. When you tiptoe, the contraction of the posterior calf muscles on both sides can promote blood return in the lower limbs, accelerate blood circulation, and thus prevent lower limb venous thrombosis. Image source: Photo Network Lift your legs Sit on a stool, lift one leg, wait until your leg feels a little sore, then switch to the other leg. Image source: taken by myself If you really can’t remember these movements, it doesn’t matter. We’ve all done radio gymnastics, stretching exercises, body rotation exercises, chest expansion exercises…all work! The key is to get moving!
