About This Practice
Cold plunge at 5-10°C for 3-5 minutes. Maintain calm breathing. Focus on embracing the cold, not fighting it.
How to Practice
Prepare a tub at 5-10°C. Enter feet first, sit down slowly, submerge to the shoulders. Do not plunge or jump. Breathe slowly through the nose from the moment you enter — do not let the initial shock steal your breath. The cold will feel sharper than a beginner bath: expect a more intense first 45-60 seconds before breathing settles. Stay still. Movement breaks the thermal boundary and feels colder. Stay for 3-5 minutes. Exit before shivering becomes uncontrollable. Dry off, dress warmly, move around. Avoid a hot shower for 20 minutes to maximise brown fat activation and natural rewarming.
Tips
Embrace the cold rather than brace against it. Mental tone changes the experience.
Stay still in the water. Movement cools you faster.
Natural rewarming over 20-30 minutes outperforms hot shower for metabolic benefit.
Three minutes at 8°C is a solid intermediate target. Five minutes is strong.
If breath management slips, exit rather than tough it out.
Precautions
Not suitable for anyone with uncontrolled cardiovascular or blood-pressure conditions.
Do not practice alone until you have 10+ successful sessions at intermediate temperature.
Watch for prolonged uncontrollable shivering after exit — this is your signal that the session went too long.
