How to hold your breath when swimming
1. Take many deep breaths before holding your breath formally. Every time a person breathes, he will not exhale all the air he inhaled into his lungs last time. The oxygen in this part of the air has been used and is not fresh. Take a deep breath many times before holding your breath to completely eliminate this part of the gas from the body. When you inhale deeply again, the inhaled gas is completely fresh air. In addition, taking many deep breaths first can fully expand the lungs, so that more air can be inhaled than usual.
2. Inhale all the air into the lungs, and after holding your breath, exhale some air from the lungs and leave it in your mouth. After a while, breathe the air from your mouth into your lungs, then exhale some air from your lungs and leave it in your mouth, and so on. This is done in order to make alveoli fully contact with the air inhaled into the lungs and maximize the utilization rate of oxygen in the air.

Do you breathe with your mouth or nose when swimming?

It is necessary to form a good habit of breathing through the mouth in order to effectively prevent suffocation.
If you accidentally inhale water through your nose in the water, don't panic and surface as soon as possible. First spit out the air in the lungs through the nose, then inhale through the mouth and continue to spit it out through the nose. The water that enters your lungs will come out with a few coughs.

In the first 20 minutes, the body mainly relies on the heat provided by glycogen to maintain physical fitness; In another 20 minutes, the body will break down fat to provide energy. Therefore, for people who want to lose weight, 40 minutes can play a role in losing weight.
In addition, beginners should not stay in the water for too long at a time. Generally speaking, 10- 15 minutes is the most suitable. Do warm-up exercises before entering the water, then drench your body with cold water, and then enter the water after your body adapts to the water temperature.
