What are the hazards of sedentary?

What are the hazards of sedentary? Is sitting as long as sleeping in bed in a day? In fact, sedentary can also be harmful. Let's talk about some diseases caused by sedentary, which can be used as a reference.

1. Heart disease

Sitting for a long time, muscles burn less fat, blood circulation slows down, and fatty acids are easy to deposit in blood vessels, causing cardiovascular and cerebrovascular diseases such as myocardial atrophy, arteriosclerosis, hypertension and coronary heart disease.

2. Diseases of digestive system

Sedentary will weaken gastrointestinal peristalsis, reduce the secretion of digestive juice, and cause indigestion and duodenal ulcer.

3. Lumbar sprain

Studies have shown that bad sitting posture can make the pressure in the lumbar intervertebral disc soar to 1 1 times that in supine position. If the back muscles are stretched for a long time, it is easy to cause muscle strain, destroy the stability of the lumbar spine and cause lumbar disc herniation.

4. Thrombosis of lower limbs

When the contraction of leg muscles decreases and the blood flow velocity of lower limbs slows down, the risk of thrombosis will increase sharply. Studies have shown that the risk of deep vein thrombosis in lower limbs will increase by 2 times if you fix a sitting position for more than 3 hours every day.

5. Cognitive impairment

Sedentary will lead to insufficient blood supply to the brain, which will slow down the brain and make the memory worse; It may also lead to fatigue and insomnia, and increase the possibility of cognitive impairment.

6. Hemorrhoids

If you sit for a long time, the blood flow in the abdomen will slow down, the venous blood in the lower limbs will not go back, and the blood circulation will be hindered. In this case, the rectal venous plexus is prone to varicose veins, leading to congestion and eventually forming a venous mass, that is, hemorrhoids.

Second, how to exercise to relax the body muscles after sedentary?

1, thigh stretching

The body adopts a natural standing posture, with the right leg raised, the forefoot placed in a fixed position, the left leg upright, the toes pointing straight ahead, and the knees of the right leg bent and pressed down. After feeling the stretching of the left leg, keep it for 5- 15 seconds before resuming the movement, and the movements on both sides alternate.

Step 2 stretch your legs

Step forward with your left foot and lean against the wall, with your left ankle bent upward and your toes pointing upward. Move the upper body forward, hold it for 5- 15 seconds after the calf feels stretched, then resume the action and alternate your legs.

Step 3 stretch your back

Take a natural posture or bend your legs slightly and cross your arms around your shoulders. Lean your shoulders forward slowly, feel stretching and stay for 5- 15 seconds before relaxing.

Step 4 Stretch the waist

Sit in a chair, bend your knees to the outside of your right leg, and support them at the joint of your left leg with your right arm. The left hand naturally leans back, the head twists to the left, and the right hand helps the left leg stretch to the right. After you feel the waist stretching, stay for 5- 15 seconds, and the movements on both sides are exchanged.

5. Shoulder and neck stretching

1. Take a natural standing or sitting posture and keep your upper body upright. Cover your head with your left hand and your right hand will droop naturally.

2. Slowly tilt your head to the left when inhaling until you feel a slight stretch. Exhale and slowly rotate your head forward on the basis of tilt until the stretching feeling changes from the right side to the right rear side. Keep it for 5- 10 seconds and then restore it naturally. Relax and be the other side.
