How to Do the Wim Hof Breathing Method: 3 Rounds of Cold Exposure

Wim Hof, “The Iceman,” holds the Guinness record for longest ice bath (1 hour 52 minutes). His method has 3 parts: breathing, cold exposure, and meditation. It’s backed by real science — Radboud University studies (2014, 2016) showed his method activates the sympathetic nervous system at will.

This is NOT for everyone. Start with just 3 rounds. Don’t do this in water or while driving.

The breathing (3 rounds)

Round 1

• 30-40 deep breaths, full chest
• Inhale through nose, exhale through mouth (lightly)
• Last breath: HOLD, as long as comfortable
• After hold: inhale deeply, hold 15 sec
• This is 1 round

Round 2

• Same as Round 1

Round 3

• Same as Round 1

After 3 rounds

• Lie down for 5-10 minutes
• You’ll feel tingling, warmth, euphoria
• This is normal — it’s adrenaline without stress

The cold (after breathing)

• End your shower with 30-60 seconds of cold water
• Or: face in cold water for 30 sec (only safe if you’re not alone)

The cold “locks in” the breathing effects by training your vagus nerve.

Safety first

• ✅ DO practice on a soft surface (bed, yoga mat)
• ✅ DO practice in the morning, not before bed
• ❌ DON’T practice in water (shower, pool)
• ❌ DON’T practice while driving
• ❌ DON’T practice if you have heart conditions
• ❌ DON’T stand up too fast after (dizziness)

What the science says

• 2014 study (PNAS): Wim Hof group produced more anti-inflammatory cytokines
• 2016 study: Hof group voluntarily activated sympathetic nervous system
• 2018 study: reduced flu symptoms with Hof method

Common mistakes

• Doing too many rounds (10+) — start with 3
• Practicing in the car — risk of fainting
• Skipping the cold exposure — breathing + cold work together
• Doing it before bed — it’s energizing, not calming
