First of all, choose a swimming place that suits you. Swimming places should be safe and hygienic, with clear water and professional lifeguards and facilities. Especially for non-professional swimmers, don't choose places with fast water or places with too deep water to avoid danger.
Secondly, pay attention to your physical condition. Before swimming, make sure you are healthy and have no chronic diseases such as heart disease and high blood pressure. If you have the above diseases, you should swim under the guidance of a doctor.

Pay attention to the breathing rules when swimming, and don't hold your breath. In case of emergency, keep calm, don't panic, and seek rescue or take self-help measures as soon as possible.
In a word, swimming is a healthy and happy exercise, but we should pay attention to the safety and rationality of swimming. Choose a suitable place, pay attention to physical condition and swimming skills, master the appropriate swimming time and intensity, and pay attention to safety measures.
