2. Don't go swimming alone, don't go swimming in places that don't know the water situation or are more dangerous and prone to drowning accidents.
3. Be self-aware of your water quality. Don't show off your talents after entering the water. Don't dive and snorkel rashly, and don't fight with each other, lest you drown by drinking water. Don't swim in rapids and whirlpools, let alone drink and swim.
4. Make proper preparations before swimming to prevent cramps. If you suddenly cramp in the water and can't get ashore, call for help immediately. If there is no one around, you can take a deep breath and dive into the water, straighten your cramped legs and pull your toes up with your hands to relieve cramps.
5. If you suddenly feel unwell during swimming, such as dizziness, nausea, palpitation, shortness of breath and so on. , should immediately go ashore to rest or call for help.
6. Don't panic if you accidentally drown for some special reason. When you find someone around you, call for help immediately, relax, let your body float on the water, head out of the water, kick the water with your feet to prevent physical loss and wait for rescue. You can press your palm down when you sink.
