Short answer: Answer a few questions and see an example beginner progression for cold plunging. This is general information, not a prescription, and it will not show a plan if you flag a health concern. Cold water strains the heart and circulation, so talk to your doctor first. See cold plunge safety and our disclaimer.
Example ranges only. Use a thermometer and a timer, and stop for numbness, dizziness, confusion, chest pain or uncontrolled shivering.
