Most people start with 30 seconds to 2 minutes at a moderately cold temperature, around 10 to 15°C (50 to 59°F), and build up gradually. Many regular users stay 2 to 5 minutes. Colder water means shorter sessions. Get out if you feel numb, dizzy or start shivering hard, never plunge alone or after alcohol, and talk to your doctor first if you have heart, blood pressure or circulation conditions.
Time in the cold matters less than consistency and safety.
Typical ranges by experience
| Experience | Temperature | Time |
|---|---|---|
| First sessions | 12 to 15°C (54 to 59°F) | 30 seconds to 2 minutes |
| A few weeks in | 8 to 12°C (46 to 54°F) | 2 to 3 minutes |
| Regular users | Around 4 to 10°C (39 to 50°F) | 2 to 5 minutes |
These are common practice ranges, not medical advice.

Common questions
Is colder always better?
No. Colder water is more stressful and needs shorter sessions. Many people get what they want from moderate temperatures.
Should I plunge right after strength training?
Some research suggests cold immersion straight after strength sessions may blunt muscle gains. Many people plunge on separate occasions or before training instead.
How do I warm up afterwards?
Dry off, dress warmly and move around. Avoid a very hot shower straight away if you feel light-headed.
