To many of those who want to know how to breathe better, I always ask them “Have you ever considered playing sports?” Athletes are always running around and working out at the gym. When they are doing all of those amazing feats, they are breathing heavily. How do they avoid having heart attacks then? Their bodies are very fit and healthy, so they are able to control their heavy breathing easily.
Some people say that if you have asthma, you should never jump into sports. But actually, if you progress slowly and build yourself from the bottom up, playing sports is the best way to improve breathing. Getting good at a sport is a goal that takes time. But over time, your body will adapt to a higher level of breathing.
