Correct sitting posture: remember the principle of "chest from the edge of the table a fist", if you always forget, you may want to bring along the exaggerated shape of the necklace, or cut half a tennis ball card on the edge of the table facing the chest, can play a very good reminder. Can also try every two weeks for another hand to use the mouse (mouse left and right button can do the opposite setting), can also effectively avoid the body always tilt to one side.

2. Leaning on the desktop with cheeks and looking at the screen with slanted eyes causes migraine

Leaning on the desktop and staring at the screen? Put the handset between the shoulder and head to answer the phone? These postures will make the muscles near the cervical spine overly tense and reduce the blood supply to the cerebral cortex. Also, too high or too low a computer screen, you will unconsciously shrug your shoulders, hunchback, so that the cervical vertebrae are also deformed, and very easy to cause migraine.

3, The desktop is too high, shrugging shoulders, bladder operation keyboard, and mouse, resulting in mouse hand　

Women's wrists are thinner, the nerve in the middle of the wrist is subject to greater pressure, so the mouse hand attack rate of women is more than three times that of men. Pressing the palm down and supporting the wrist on a table puts all the weight on the nerves, muscles, and blood vessels of the wrist, and the degree of dorsiflexion of the wrist joint is almost at its maximum. If this situation exists for a long time, the blood circulation of the hand will be affected, the mouse hand naturally find the door.

Correct sitting posture: the higher the position of the keyboard and mouse, the greater the degree of wrist dorsiflexion, we can put them in a slightly lower position according to their situation. Arms naturally down, the height of the elbow joint is the height of the keyboard and mouse placement; at the same time every half hour to move both wrists, shake fists, do finger exercises.

Unconsciously crossed legs? This posture will limit the blood flow in one leg, and the weight of the upper body will be pressed on one leg, causing the spine to bend and the back to stiffen. Also, the chair can not be adjusted or no backrest, often causing the body to lean forward excessively, making the symptoms of spinal curvature and lumbar disc herniation more serious.

Correct sitting posture: everyone's body shape is different, so the office seat is best to choose a manual "adjustment type". The height of the chair should be able to make the feet can be flat on the floor, the thighs should also be parallel to the floor; the chair back should be close to the back and keep the tilt of about 120 degrees. Oh yes, if you need to look at the computer screen for a long time, it is best to choose a high-backed chair to support the entire back.

6, The chair is too high or too low, the knee joint can not be a right angle, resulting in elephant legs
