What are the precautions for physical exercise?

For people in today's life, physical exercise is a very necessary activity. Because physical exercise can help people establish a new outlook in life, make people more energetic at work, and also enable everyone to have a healthy body in life and fight against diseases, so what should we pay attention to during physical exercise?

Avoid exercising under strong light: Around noon, the sun is high in the sky and the temperature is highest. Except for swimming, avoid exercising at this time to prevent heatstroke.

Avoid exercising for too long: The exercise time should not be too long, 20 to 30 minutes is appropriate, so as to avoid excessive sweating and excessive rise in body temperature, which may cause heatstroke.

Avoid drinking a lot of water after exercise: You sweat a lot during exercise in summer. If you drink a lot of water at this time, it will increase the burden on the circulatory system, digestive system, and especially the heart. At the same time, drinking water will cause more sweating and further loss of salt, which can cause symptoms such as cramps and spasms.

Avoid taking a cold shower immediately after exercise: because the body's heat production increases rapidly during summer exercise, and the capillaries in the skin also expand significantly to help the body dissipate heat. Sudden cold stimulation can cause the open pores on the body surface to suddenly close, causing disorders of the body's internal organs, abnormal temperature regulation of the brain, and even illness.

Avoid drinking a lot of cold drinks after exercise: physical exercise can cause a large amount of blood to flow to the muscles and body surface, while the digestive system is in a relatively anemic state. A large amount of cold drinks not only lowers the temperature of the stomach, but also dilutes the gastric juice, which can cause indigestion at the mildest and acute gastritis at the worst.

Physical exercise is a good choice for people, but people also need to tailor a scientific and reasonable exercise plan for themselves according to the situation, so that their lives can become more colorful and everyone can have a happier and sunny life.
