Good and sufficient sleep helps to eliminate fatigue, restore physical strength and energy, and at the same time helps to enhance human immunity, maintain a happy mood and maintain the normal conduct of psychological activities. For teenagers who are still in the growing period, adequate sleep can also promote growth and development. Even so, the more sleep, the better. Because when people sleep, blood circulation slows down, and the supply of nutrition and oxygen to the brain is greatly reduced. If the sleep time is too long, the brain cells will not get enough nutrition, and their activities will be weakened. At the same time, excessive relaxation of muscle tissue for a long time can also cause fatigue. Therefore, many students still feel tired and listless after sleeping for more than ten hours, and may even have symptoms such as dizziness and headache.
Generally speaking, teenagers should sleep for about 8 hours. The younger they are, the longer they need to sleep. Children under 10 should sleep for 9- 10 hours. Children are at home on holiday, and there is no strict time limit for going to school the next day, so it is inevitable to stay up late. However, for the sake of children's health, parents should control according to the situation to avoid the situation of "getting more and more tired".
Encourage children to take part in outdoor sports and do simple housework as much as possible. Children are usually busy with schoolwork and have less exercise time. Only going to physical education class twice a week can hardly meet the needs of physical and mental health. Holidays are a good time to increase exercise. Although the winter vacation is in the middle of winter, it is difficult to insist on outdoor sports alone, but there are many exercise methods to choose from, such as skipping rope, kicking shuttlecock, badminton, table tennis, basketball and so on. If the space and conditions are really limited, climbing stairs is also a good choice. It is suggested to arrange 30-60 minutes of moderate and low intensity exercise every day, which can not only promote physical and neuromuscular development, improve human immunity, enhance cardiopulmonary function, but also facilitate the secretion of psychological "euphoria" and keep people happy and energetic.
Parents need to be clear that in addition to schoolwork, they should also pay more attention to their children's experiential learning during holidays. At school, children focus on learning, and parents rarely plan to let their children participate in housework. It is also an exercise to let children do some simple housework during the holiday.
