Ice bathing works best with preparation and mindfulness. Beginners should only enter the water in good health and slowly acclimatise to the cold. Choose a safe place without a current and with an easy exit. Before entering the cold water, warm up briefly with light exercises. When entering the water, it is important to breathe calmly and evenly to control the initial cold shock. To start with, 30 seconds to 2 minutes is usually enough. Always pay attention to your body signals - dizziness or numbness are warning signs.
