Many people like to sit cross-legged or put one foot on the other. But over time, it will cause muscle imbalance on the left and right sides of the leg, affect the waist muscles, legs and waist, and feel a little sore. It is suggested that more attention should be paid to the comfort of sitting cross-legged. After sitting for a while, you should exercise and relieve fatigue to ensure the comfort of your waist and legs.
Some people are used to leaning forward when sitting in order to see the computer screen clearly. Full screen will hurt their waist. Sitting at the waist like this will make you nervous. The correct sitting posture is straight back. When sitting cross-legged, try to adapt to the computer desk and don't bow too much. It is best if the table is next to the bed, so that the legs can be naturally placed under the bed and the legs and back will not be so tired.
How to be sedentary and not tired?
1, thighs are parallel to the ground.
Try to make the table flush with the wearer, or the chair parallel to the ground, which can reduce the pressure on muscles, tendons and bones and prevent musculoskeletal diseases. When sitting in a chair, choose an armchair and put a rolled-up towel or headrest at the waist. The hand, wrist and forearm are in a straight line, so that when the front arm is placed on the desk, the elbow is at right angles, and the head and body are kept in a straight line, leaning forward slightly. Elbows should be close to the body, and it is appropriate to bend 90- 120 degrees. Relax your shoulders, let your upper arms droop naturally, and put your feet flat on the floor.
2, often walk around
The Mayo Clinic in the United States found that the body can withstand the same sitting position for 20 minutes, and then it will feel uncomfortable. It is recommended to stand up, stretch or walk every 15 minutes and change the sitting posture for at least 30 seconds.
3, reduce repetitive actions, and the distance from the screen should be appropriate.
Repeated actions will inevitably lead to fatigue and stress. Ordinary items such as telephones should be kept within reach. You can use the computer mouse with your left hand and your right hand. At least 50 cm in front of the computer screen, the screen height is slightly lower than the eye height. Don't point the screen at the window to avoid reflection.
