It is important to breathe properly while doing sports. Some people may experience headaches and chest discomfort (burning bronchi?) when they do physical activity if they are not breathing adequately. Make sure to focus on breathing through both your nose and mouth to ensure you are getting enough oxygen to your body. If you have a medical condition such as asthma, it may be helpful to use a bronchodilator before exercising to help with breathing. It is always a good idea to consult with a healthcare professional for further advice on managing any symptoms you may experience during physical activity.
