Recovery
Cold Plunge After Workouts: Benefits, Temperature, Downsides
Published October 20, 2026
A cold plunge (sitting in water around 50-59 °F / 10-15 °C for about 10-15 minutes after exercise) modestly reduces muscle soreness in the following days, but used routinely after strength training it can reduce gains in muscle size and strength. It makes most sense between closely spaced efforts (tournaments, multi-day events), not after every lifting session.
What the research says
| Study | Finding |
|---|---|
| Machado et al., 2015 (meta-analysis) | Cold water immersion reduces muscle soreness; best results with water at 11-15 °C (52-59 °F) for 11-15 minutes |
| Roberts et al., 2015 | After 12 weeks of strength training, regular cold water immersion led to smaller gains in muscle mass and strength than active recovery |

When to use it
| Situation | Cold plunge? |
|---|---|
| Tournament, several games in 48 h | Yes |
| Multi-day race or training camp | Yes |
| After a competition, for comfort | Sure |
| After every lifting session | No, it may blunt your progress |
| Endurance training block | Occasionally |
| After an easy run | Not needed |
Protocol
- Water at 52-59 °F (11-15 °C), no need for near-freezing.
- Immerse to waist or chest for 10-15 minutes.
- Within 30 minutes after exercise.
- Rewarm gradually afterward.
At home: a bathtub with cold tap water plus some ice and a thermometer. Cold showers are less studied and likely weaker.
Alternatives that work
| Method | What we know |
|---|---|
| Sleep 7-9 h | The foundation of recovery |
| Meal with protein and carbs | Essential after hard sessions |
| Active recovery (easy bike 15 min) | Good compromise |
| Foam rolling | Improved some recovery measures in pro soccer players (Rey et al., 2019) |
| Massage | Comfort, soreness |

Safety
Avoid cold plunges with heart disease, uncontrolled high blood pressure, Raynaud's, pregnancy, or without medical advice if you are frail. Never plunge alone in open cold water. Enter gradually: the cold shock makes you hyperventilate.
FAQ
Cold plunge or sauna? Sauna relaxes; cold eases soreness. Neither replaces sleep.
What about whole-body cryotherapy? More expensive, no better evidence.
