What are the precautions for outdoor sports in winter?

The temperature is low in winter, and the low temperature environment also has some effects on the body, mainly in:

A. Low temperature will make muscles stiff and increase viscosity, which is easy to cause sports injuries.

B. When the outdoor temperature is too low, frostbite sometimes occurs in exposed parts and parts with poor blood circulation.

C. the excitability of the nervous system decreases at low temperature. Excessive body temperature loss will make the body feel dizzy, the coordination ability will decrease, and the gait will be unstable.

D. When the temperature is low, the human body needs to increase heat production to maintain body temperature, which will lead to increased metabolism of energy substances and increased oxygen consumption.

Therefore, winter sports should pay attention to the following aspects:

A. keep warm to avoid catching a cold. Wear appropriate clothes, shoes and socks to keep warm during exercise. Prepare more clothes so as to increase or decrease at any time.

B. In order to prevent frostbite, gloves and hats should be worn on exposed parts of the body. Protect your face and apply some moisturizing skin care products. Wet shoes and socks should be replaced in time to prevent toe frostbite.

C. be fully prepared before exercise. In winter, the weather is cold, blood vessels contract, blood circulation is not smooth, and muscles and ligaments are tight. If you don't do enough preparatory activities, it is easy to cause muscle strain, ligament tear and even fracture.

D. When using fitness equipment outdoors, it is best to avoid direct contact with the skin. When human skin comes into contact with cold metal, it will stick and cause harm. Therefore, it is best to wear gloves when using metal instruments. Gloves and shoes should be non-slip, so as to avoid getting rid of them or slipping during exercise and causing injuries.

E. outdoor sports, don't choose projects that have been static for a long time.

F. When doing outdoor sports for a long time, reasonably distribute physical strength to ensure the normal heat production of the body.

G. It is best to eat enough food before exercise to ensure the supply of energy during exercise.

H. it's best to get into the habit of breathing through the nose. Nose hair can filter the air, reduce the damage of dust and viruses to the respiratory system, and also warm the cold air and reduce the stimulation of cold air to the lungs.
