Recent researches have shown that how you breathe can tell you how relaxed or how tense you are. So if you want to keep a tranquil mind and not to feel anxious all the time, you should pay attention to your breathing. For example, when you are calm, your breathing is deep and steady. Your breath mainly comes from the stomach, not the chest. But when you are nervous, excited, or under pressure, your breathing changes. It becomes shallow and ragged; that is, it is short and quick. It comes mainly from the chest or throat. Sometimes, when upset, you may even catch yourself holding your breath without knowing it. Or you may exhale more quickly than you inhale. So whenever you want to calm down, try to breathe to a rhythm. Inhale to the count of three; exhale to the count of four. Then get in the habit of checking your breathing from time to time to make sure you stay relaxed and at your best.
