Deep breathing is a quick way of hijacking anxious thoughts and giving them the boot. Whenever you start to feel overwhelmed with intrusive, fear-provoking thoughts, recognize what is happening, and tell your mind to stop. Then begin taking in deep breaths. Breathe in for a count of four, hold for a count of four, exhale for four, and hold for a count of four again. Some people refer to this technique as “square breathing” because there are four sides, all that come out to a count of four. Whatever you call it, it works.

Deep breathing is so effective because it switches your brain’s activity from the sympathetic nervous system, which is related to anxiety, to the parasympathetic nervous system related to calmness and happiness. The immediate effect is fewer distressing thoughts and an increased ability to focus. Over time, deep breathing can lower your blood pressure while improving other aspects of overall health and well-being.
