With PMO comes a trail of moodiness, regret, anxiety, irritability and even depression. This in turn leads to more PMO as a "feel good" high. It's a bad loop and we all have to recognize our triggers/urges. I feel breathing exercises elicit a state of meditation and mindfulness, along with pumping some good ol' euphoria into the mix. I personally replace stress/anxiety/edging w/ WIM HOF BREATHING. It helps with mind clarity, oxygenates the blood, balances the acid/base of the blood, reduces inflammation and feeling of general malaise/fatigue/cloudy head. HOW: (link) YOUTUBE GUIDED WIM HOF BREATHING VIDEO 1) Make sure you're not driving or submersed in water 2) find a safe place to practice sitting/laying down 3) INHALE DEEP + FULLY (through nose/mouth) + EXHALE (let go; don't exhale fully) 4) COMPLETE 30 CYCLES; after #30 EXHALE + HOLD BREATHE FOR AS LONG AS POSSIBLE. FEEL. BE AWARE. BE MINDFUL. ENJOY THE TINGLING AND EXPERIENCE THROUGHOUT THE BODY. 5) ONCE YOU NEED TO BREATE, BREATHE! INHALE DEEPLY + HOLD FOR 10s THIS IS 1 CYCLE OF WHM (WIM HOF METHOD) BREATHING.
