Follow Wim Hof’s breathing technique

Find a comfortable position.
Before you start, find a comfortable position by sitting or lying down in a safe and quiet environment. Make sure your chest is relaxed, and you can fully fill your lungs.

Take 30-40 deep breaths.
Breathe deeply with your diaphragm into the stomach first, then fill your lungs. This may feel slightly uncomfortable but should not be painful. You can breathe through your mouth or nose, whichever feels most comfortable. When you exhale, don’t force it, just let the air go. You should be inhaling slightly more than you exhale.

Take one final deep breath and hold it.
After 30-40 breaths, take one final inhale and exhale. Then, hold your breath and relax.

Clear your mind.
While holding your breath, clear your mind and pay attention to the sensations in your body. You may feel tingling sensations in your hands and feet, which is perfectly normal.

Take a recovery breath.
When you feel the urge to breathe, inhale and hold the breath for 15 seconds before releasing the air and emptying your lungs.

Repeat for 3-4 rounds.
Once you have released the recovery breath, start the process again and repeat it 3-4 times. When you have finished, give yourself a few moments before you get up and start moving around.
