First of all, we need to understand that the purpose of warm-up activities is to make your body a little hot, but not sweating, so as to avoid the sharp contraction of skin blood vessels caused by excessive temperature difference. Therefore, through proper physical activities or singing, we can achieve our goals.
Also pay attention to, don't get into the water immediately after taking off your clothes. Instead, you can rub your whole body's skin and joints, wet your hands and feet with cold water, beat your chest and back, so that your body can adapt in advance, avoid dizziness, nausea, rapid heartbeat, muscle cramps and numbness of your feet, and make your winter swimming smoother.
In addition, we do not recommend people who have no previous winter swimming experience to participate in winter swimming activities rashly. If you want to take part in winter swimming, you must first have certain swimming skills, and you must swim at least 500 meters to achieve your goal. After you have swimming skills, you should try to make your body have considerable temperature adaptability. Bathing can be changed from warm water to cold water, and the temperature will gradually decrease. You can adapt to the water temperature of more than ten or twenty degrees in summer and autumn, and then gradually transition to the temperature in severe winter to ensure that your body can adapt to this temperature change, and then participate in winter swimming.
Especially in the north, the water temperature ten to twenty days before freezing is very challenging, so if you want to swim in the water during this period, you should exercise better. Taking part in winter swimming itself is to exercise, and necessary safety protection is indispensable.
