：Some skills about breathing in freestyle swimming are as follows: 1. **Focus on exhalation**: Exhale underwater, so that when it's time to breathe in, you just need to take an inhalation. This makes breathing easier, helps to relax, and is beneficial for bilateral breathing. 2. **Keep the head stable**: Between breaths, keep your head from shaking or rolling. Only turn your head around the axis of the body's centerline when breathing, and only turn it when breathing. Imagine there is a glass half-filled with champagne on your head, and you must keep your head stable, otherwise the champagne will spill. You can also practice by bending forward in the shallow water or on the shore, simulating the arm stroke while keeping your head still. 3. **Breathe by using the vortex**: When swimming, the movement of your head and body will create a "vortex", similar to that produced by a small boat, forming a groove on both sides of your head and body. The groove is located below the water surface where there is air. When breathing, turn your head to one side and breathe in the trough without the need to lift your head to inhale. You can feel this by holding onto the edge of the pool with one hand, kicking your legs while practicing side breathing. 4. **Avoid lifting your head**: Lifting your head will disrupt your body balance, causing your legs to sink, increasing drag resistance, and disturbing the vortex. Believe in the existence of the air pocket and keep your head in a low position. You can use flippers and practice swimming in a superman position, with one arm extended in the front and the other arm at the hip position, the leading arm gently kicking the water while looking down at the bottom of the pool. When breathing, slightly turn your head to find the air pocket for breathing. 5. **Prevent excessive head turning**: Excessive head turning will cause you to look upwards instead of sideways when breathing, which will over-turn to the breathing side and lose balance, resulting in the leading arm crossing over the head and the body forming a banana shape, causing problems similar to scissor legs. To correct this, you need to get used to breathing in the groove. You can practice by doing side kicking, and try to keep the lower part of the goggles in the water when attempting to breathe, so that one eye is below the water surface and one eye is above it. 6. **Take advantage of body rotation**: Good body rotation is of great help for breathing. After rotating the body, you don't need to turn your head too much when breathing. If you struggle with breathing, it may be caused by insufficient body rotation. 7. **Learn bilateral breathing**: This helps to develop a symmetrical stroke technique and allows your body to swim in a straight line in the water. If you only breathe on one side, your body may not turn enough to the non-breathing side, resulting in an inability to swim in a straight line. When learning to breathe in freestyle swimming, it is necessary to progress step by step, keep practicing, and gradually master these skills. At the same time, maintain a relaxed state, don't be too tense, and breathe naturally without taking large mouthfuls of air or breathing out quickly. The nose can control the speed of exhalation, for example, by humming the exhaust out of the nostrils like singing, and use the mouth to exhale only when it is more intense. After mastering the rhythm, you can try the breathing rhythm of "uh uh uh uh... pop!" That is, keep humming with your nose until your mouth suddenly opens just before coming out of the water, making a "pop" sound, which can easily blow away the water around your mouth and get fresh oxygen. At the beginning, you can stand in place and practice this rhythm first, and then add body rotation after getting proficient.
