Deep breathing increases the supply of oxygen to your brain and stimulates the parasympathetic nervous system (which is a network of nerves that relaxes your body during periods of stress or danger).
Breathing exercises are easy and can be practiced anywhere - you can even practice them right now, as you’re reading this answer! The key, of course, is focused breathing, and here’s one way to do it.
Start by getting comfortable. Loosen any restrictive clothing, and find a position that is comfortable for you, including sitting down, laying down, or if neither is possible, even standing up
In this position, rest your feet on the floor, place one hand on your chest and the other hand on your belly
Inhale through your nose, letting your breath flow deep down into your abdomen, and feel your belly expand into the hand resting on it. The hand on your chest should remain as still as possible
Breathe out through pursed lips, slowly and steadily
Repeat the cycle, concentrating on your technique and timing, taking slower and deeper breaths than your regular breathing pattern for 3-5 minutes, or until you feel calmer
