Ice bath timer
A free ice bath timer that loads two minutes, the usual target for a first cold plunge. Big digits and a bright ring are easy to read from a tub when your hands are too cold to touch a phone. Also searched as cold plunge timer, cold water immersion timer, 2 minute ice bath timer. This page is not medical advice. People with heart conditions, high blood pressure, Raynaud's or who are pregnant should ask a doctor first.
Time and temperature guide
| Level | Water temperature | Time in | Preset |
|---|---|---|---|
| First sessions | 55 to 59°F | 1 to 2 minutes | This page |
| After a few weeks | 50 to 59°F | 3 to 5 minutes | 3 minute timer, 5 minute timer |
| Experienced | 45 to 55°F | Up to about 10 minutes | Edit the digits |
| Weekly total, common target | About 11 minutes across 2 to 4 sessions |
The 11-minute weekly figure comes from a widely cited protocol based on cold-exposure research. It is a target for people who are already comfortable, not a starting point.
Safety rules
- Never alone. Have someone within earshot.
- Breathe out slowly on entry. The gasp reflex passes in about 30 seconds.
- Get out early if you lose feeling in hands or feet, shiver uncontrollably or feel confused. The timer is a cap, not a goal.
- Warm up naturally afterward: dry off, dress, move. Skip the hot shower for a few minutes.
- Enter and exit carefully. Numb feet slip.
Pairing with heat
Many people alternate a sauna round with a short plunge. The sauna timer page has a three-round protocol. Keep the cold part short on those days. The plain 2 minute timer is the same preset without the notes.
Frequently asked questions
How long should a beginner stay in an ice bath?
One to two minutes at 50 to 59°F is a sensible start. Build toward three to five minutes over several weeks, and stop well before ten.
What water temperature counts as an ice bath?
Most protocols use 50 to 59°F. Colder water needs shorter times and more caution; it is not better, just harsher.
Is it safe to do alone?
It is safer with someone nearby. Cold shock can take your breath away, and getting out of a tub with numb legs is harder than getting in.
