Here is a step-by-step guide to Wim Hof breathing:
Sit down in a comfortable position with your spine straight.
Take a deep breath in through your nose, filling up your stomach first and then your chest.
Breathe out through your mouth, exhaling fully until your stomach and chest are both empty.
Repeat this process for 30 breaths.
Once you have finished the 30 breaths, take a deep breath in and hold it for as long as you can.
Exhale fully and repeat this process for 3-5 minutes.
Once you have finished the breathing exercise, sit for a few moments and notice how you feel.
