Sitting in front of the computer for a long time will make people very tired and do a lot of harm to their eyes. Holding the mouse for too long, or sitting incorrectly, will cause shoulder and arm pain, which will extend to the whole arm in severe cases, and there will be problems of inattention.

Experts suggest that every 30 minutes online, you should stand up and walk around, or close your eyes for 2 minutes to protect your eyesight and promote blood circulation in your limbs. It would be better if you could do the following simple "aerobics":

Rub your eyes. After closing your eyes, gently press your forefinger on the eyeball and massage clockwise and counterclockwise for 20 times. Then gently massage the forehead and temples on both sides for 30 times to relieve eye fatigue.

Nod. First bow your head and then raise your head, repeat 20 times; Then turn left and then right, and do it 20 times. This can relieve the fatigue of the neck muscles.

Turn your neck. Turn your head from left to right, then from right to left, and repeat for 20 times, which can also relieve the fatigue of neck muscles.

Stretch your arms. Lift your arms vertically up to the ground, lock your hands with four fingers, palm up, and take a deep breath at the same time. Keep your arms up and reach out for 10 second to promote oxygen inhalation and relieve fatigue.

Squat up. Sitting in front of the computer for a long time will affect the blood circulation of lower limbs, and even when you just stand up, it will appear dark. After standing firm, do five squats to exercise the lower limbs.
