1. Take a shower before going into the water: This is actually a behavior related to personal health and public health, because the human body will produce a lot of sweat stains, grease, inorganic salts and urea, in addition to the hair that may be brought into the pool and the dirt carried by the body. If you don't wash it, it will pollute the water quality, and the oil stains and sweat stains on your body will absorb a lot of dirt on your body, which is also very unfavorable to you.
2. Fully warm-up: Now there are more and more people swimming and fitness, and I find that there are not many friends who warm up seriously on the shore. Most people are reluctant to do simple stretching. Generally speaking, they just splash a few times on their bodies and go straight into the water, and then they sprint. This kind of swimming is very harmful to our health, so I suggest you warm up first and then go into the water.
3. Right-handed principle freestyle overtaking: Generally speaking, there is rarely only one person in a lane, so when we swim in the same lane, we all lean to the right and the backstroke leans to the left, which can form a good swimming order and is not prone to "collision". If the speed ahead is slower than you, you can overtake quickly from the left with freestyle. Freestyle takes up less space and is fast, which is the best way to overtake.
4. Don't press the waterline: the waterline has the function of separating the swimming space, and it can support you in an emergency. However, if you stay on the waterline, it is easy to hurt yourself or other swimmers, because the waterline is usually very sharp when passing through the steel wire, and the phenomenon of scratching your body underwater in the swimming pool sometimes occurs.
5. Don't spit everywhere: spitting in the water or on the shore will greatly affect public health and the health of others. Although many people sometimes have the desire to spit when swimming, they must pay attention to public health and spit in sputum buckets, trash cans or sewers.
These are common phenomena in daily swimming, so civilized swimming and healthy swimming can't change others, so let's start from ourselves first.
