Swimming is a widely beloved sport, cherished by many for its multitude of benefits. It enhances cardiorespiratory fitness, strengthens muscles, and boosts posture and coordination, making it a comprehensive workout.

Beyond its health advantages, swimming serves as a perfect way to cool down and find relief from the heat on sweltering summer days.

However, not everyone likes to swim. Some people may not like swimming because they are afraid of water or don't like to touch the water. Additionally, swimming requires skill and stamina, and without training and practice, it can be stressful and uncomfortable for the body.

The more common auxiliary equipment in swimming is the swimming ring, which is usually a circular airbag made of plastic, rubber, and other materials. Its main role is to provide buoyancy and support to help swimmers maintain their balance and stability in the water for easier swimming.

Here are some of the main functions of swimming rings:

- Provide buoyancy: Swimming rings can provide additional buoyancy, making swimmers more relaxed in the water, reducing swimming difficulty and fatigue, and reducing the risk of drowning.

- Support the body: Swimming rings can help swimmers support their bodies so that swimmers can maintain balance and stability, making it easier to learn and master correct swimming skills.

- Increased Confidence: Swimming rings can provide beginners with extra security and confidence, making them more willing to try and explore the world in the water, and can also master swimming skills faster.

It should be noted that the swimming ring is not a necessity for swimming, but more of an auxiliary equipment.

Swimming is a healthy and beneficial exercise, but you need to pay attention to safety and protect your body when swimming.

- Safety first: Before swimming, make sure you can swim proficiently and in a safe location. If you are new to swimming techniques, train under the supervision of an experienced person. Do not swim without a lifeguard or in hazardous areas such as deep water or whirlpools.

- Warm-up: Before entering the water, do some warm-up exercises to reduce the risk of injury. Simple stretches and warm-ups can be done on the shore or in the water.

- Pay attention to breathing: Breathing is very important when swimming, and the correct breathing method can improve swimming efficiency. When swimming, you should try to keep your breathing smooth and don't hold your breath.

- Stay level: Try to stay as level as possible without leaning your body, which creates additional resistance and unnecessary fatigue.

- See the way: When swimming, you should always be aware of your surroundings and other swimmers. During swimming, it is necessary to maintain a clear vision to avoid collisions or other accidents.

- Pay attention to heat preservation: if the water temperature is low, you need to pay attention to heat preservation. A suitable swimsuit or wetsuit can be worn, and time spent in the water should be minimized.

- Pay attention to skin care: After swimming, you should wash your skin and apply sunscreen or moisturizer in time to avoid skin damage.

If you encounter a safety problem while swimming, you should take the following steps as soon as possible:

- Stay calm: It is important to stay calm during an emergency. Don't panic, stay calm and think.

- Call for help: If you cannot cope with a security situation on your own, you should call for help immediately. It is okay to shout and seek help from those around you or a lifeguard. If you have a mobile phone, you can call local emergency numbers.

- Protect Yourself: While waiting for help to arrive, you should try to protect yourself as much as possible. If you are unable to swim, you should try to keep your head above the water. If you have scuba gear, you can try to protect yourself with scuba gear.

- Waiting for help: While waiting for help to arrive, try to remain calm and quiet. If other swimmers or lifeguards are nearby, ask them for help.
