There are many techniques for proper breathing. But in general, you should remember that any type of breathing exercise that helps accumulate carbon dioxide in blood is beneficial. So, throughout the day, pay attention to how you breathe and make sure your exhale is longer than your inhale. For example, inhale for a count of four, pause for a count of four, and then exhale for a count of six or eight. In short, accumulate carbon dioxide, and you will become healthier
