Recently, many places have experienced sustained high temperatures. How do children exercise scientifically during summer vacation? Experts remind that appropriate exercise can accelerate human metabolism and benefit physical health. However, children and other groups should not engage in outdoor exercise during high temperature periods to avoid temperature regulation dysfunction, which can lead to symptoms such as overheating, weakness, and dizziness. Zeng Saizhen, chief physician of pediatrics at Hunan Provincial People's Hospital, said that children and adolescents can choose relatively cool periods in the morning and evening for outdoor exercise during the Sanfu season. The exercise time should not be too long, generally ranging from 30 minutes to 1 hour. During the exercise process, water intake should be ensured to avoid excessive sweating, high body temperature, dehydration, heatstroke, etc. Children and adolescents who experience sustained temperature rise, headache, muscle spasms, nausea, and other symptoms after exercise should seek medical attention promptly. Summer exercise requires scientific hydration Zeng Saizhen reminds that during the hot summer season, the human body releases heat through sweating, and water in the body is easily lost. If water is not replenished in time, blood volume will decrease, blood supply to the brain may be insufficient, and headaches and dizziness may occur. Some people sweat heavily after exercise, causing the body to lose a large amount of electrolytes. While replenishing water, it is also important to pay attention to replenishing electrolytes. Children and adolescents can drink some diluted salt water after exercise to maintain water and electrolyte balance in their bodies. Zhu Weihong, Deputy Director of Orthopedics at Xiangya Second Hospital of Central South University, also reminded children to take protective measures and warm up during intense exercise. Li Haixia, director of the Traditional Chinese Medicine Department at Hunan Children's Hospital, believes that for children and adolescents, Ba Duan Jin, Tai Chi, and swimming are all good forms of exercise. Teenagers and children should not immediately blow air conditioning, take cold showers, or drink cold drinks after exercise to avoid inducing vasospasm, headaches, dizziness, and other symptoms.
