I can swim in shallow water, but I dare not go to deep water. My friends laughed at me. Please tell me the difference between shallow swimming and deep swimming. Help!

This situation of yours is a psychological obstacle of being afraid of water, because you know that the place to go down is deep water, and you imply in your mind that there is water depth here, and if you can't stand up, there will be danger. Naturally, you are afraid of water and dare not go down. As long as we try to get rid of this obstacle, there will be no problem.

1, you have to practice diving or snorkeling in a shallow pool, and the diving time will be extended slowly, so you can learn the skills of exhaling in water-exhaling in water with your nose as the main mouth, and exhaling (spitting) slowly and gently, as long as you leave a little air out of the water for air.

2. In the deep water area, you don't have to think about how deep the water is here, but imply that it is the same as the shallow pool, and then dive or snorkel on the side in the same way as above. As long as you practice a few more times, you will be fine if you get rid of this mentality.

For example, in my experience, I have been swimming for decades. I am not afraid of the depth and can swim with 5 meters of water. As a result, one day, because of the above inspection, all the water in the competition pool 3 meters deep was changed. At that time, only about 1 m of water was filled, and I was afraid to swim. I am swimming in water 5 meters deep, so I am not afraid to go down. I saw the shore of the pool below when I was backstroke. An inexplicable panic forced me to stand up. I felt funny for a moment, and I was not afraid of diving. How can I be a little flustered? The reason is that the water in the swimming pool is usually full, but now it is only one third, which is my subconscious fear of heights. Later, I went to see the heights, looking from bottom to top, and I was no longer afraid.
