How to arrange our running plan according to the weather change?
Running in winter: Due to the stimulation of cold air, the body's hematopoietic function has undergone adaptive changes, and its resistance to diseases has increased. Therefore, people who insist on running in cold weather rarely suffer from anemia, colds, bronchitis and pneumonia. In cold weather, indoor sunshine is generally weak, so running outdoors can make up for the lack of sunshine. Sunlight can promote the absorption of calcium and phosphorus by human body and contribute to the growth and development of bones. Running for the elderly can also prevent osteoporosis to some extent. Ultraviolet rays in sunlight can also kill germs on human body and clothes, playing a "disinfection role". However, it should be noted that the temperature in winter is low, and the blood vessels on the body surface contract when it is cold, the blood flow is slow, the viscosity of muscles is improved, and the elasticity of ligaments and the flexibility of joints are reduced. Therefore, full preparations should be made before running to prevent sports injuries. In addition, winter running should pay attention to the warmth of the body, hands and ears to prevent frostbite.
(1) Running in summer, the temperature is high in summer, and improper running is prone to heatstroke. Running in hot weather, it is best to choose a cooler morning and evening. Try to avoid direct sunlight when running during the day, and wear a hat to prevent heatstroke.
(2) Running in windy days will make you feel difficult to breathe. At this time, you should master the rhythm and depth of breathing, and don't open your mouth to inhale, so as to prevent cold air from irritating your throat and trachea and causing cough. If the wind is too strong and dusty, you can exercise indoors instead.
(3) Running in foggy days For suburbs and parks with good air environment, the foggy air is as fresh as the fog-free air, but the air is humid and inhalation will not affect your health, so you can run as usual in foggy days. Due to the poor visibility in foggy days, the running speed should be slower to prevent accidents such as falling. In places with air pollution, fog will prevent harmful waste gas from spreading around and aggravate air pollution. In such a place, it is not suitable for running outdoors in foggy weather.
(4) Wear a hat and gloves when running in snowy days. Choose a flat road or run on the playground. When running, the pace should be small, and the frequency can be appropriately accelerated to prevent spraining the ankle in the uneven place. When running in snowy days, because snow may lead to strong sunlight reflection, it is not advisable to run in the snow under strong sunlight, so as to avoid the reflected light hurting eyes and causing snow blindness.
