Ice Bath / Cold Plunge
Quick read: An ice bath, also known as cold water immersion, involves submerging the body in water typically below 15°C (59°F) for short periods.
How to do it
- 1 Prepare your ice bath: Fill a bathtub or large container with cold water and add ice. Aim for a water temperature between 10-15°C (50-59°F). Use a thermometer if available.
- 2 Center your breath: Before entering, take a few deep, slow breaths. Focus on calming your mind and preparing for the cold sensation.
- 3 Enter gradually and safely: Slowly submerge your body into the water, starting with your feet and progressively moving up to your chest or shoulders. Avoid a sudden full plunge to prevent hyperventilation.
- 4 Maintain duration and focus: Aim to stay in the ice bath for 2-5 minutes. Continue to breathe deeply and steadily, focusing on controlling your physiological response to the cold.
- 5 Exit and warm up naturally: Carefully step out of the bath. Avoid immediately taking a hot shower, as this can counteract the benefits. Instead, towel dry and allow your body to rewarm naturally, or put on warm, dry clothes.
- 6 Listen to your body: This practice should be challenging but not agonizing. If you experience extreme discomfort, shivering that you cannot control, or numbness, exit the bath immediately.
