Ice Bath vs Cryotherapy

Two cold-recovery methods that get muddled up all the time, even though they work in completely different ways. Here's how an ice bath and whole-body cryotherapy really compare, and how to pick the right one for you.

Published ·Last reviewed

THE SHORT ANSWER

An ice bath means sitting in cold water, usually 4 to 15°C, up to the shoulders for two to five minutes. Whole-body cryotherapy is shorter. You stand in a chamber of very cold dry air, around minus 110 to minus 140°C, for two to three minutes. The chamber sounds colder, and as a number it is. But water pulls heat out of you much faster than air does, so a full ice bath actually gives the body a bigger cold hit. It's also the one with more research behind it for easing sore muscles. Cryotherapy's plus point is that it's quick and you stay dry. RE:UP in Altrincham uses full ice baths with a sauna.

SIDE BY SIDE

Ice bath vs cryotherapy, compared

COLD WATER IMMERSION

Ice bath

Medium
Cold water, full-body immersion
Temperature
4–15°C (RE:UP runs 4–7°C)
Typical duration
2–5 minutes
Cold load
High. Cools fast and deep
Evidence for soreness
Strong, well established
Pairs with sauna
Yes, for contrast therapy

COLD AIR CHAMBER

Whole-body cryotherapy

Medium
Cold dry air, no immersion
Temperature
−110 to −140°C
Typical duration
2–3 minutes
Cold load
Lower. Mostly the skin
Evidence for soreness
Emerging, less consistent
Pairs with sauna
Not typically

THE PHYSICS

Why the colder-looking chamber isn't the bigger cold hit

The thing people get wrong about ice baths versus cryotherapy is assuming minus 130°C must beat 5°C. As a number, of course it does. But your body doesn't cool down by temperature alone. It cools by how fast heat is pulled away from it, and water does that about 25 times faster than air at the same temperature.

So a few minutes in 5°C water actually draws more heat out of you, and reaches deeper into the muscle, than a few minutes of very cold air. A cryo chamber gives a sharp surface chill and a real jolt to the nervous system, but the deeper, longer cold load that the recovery research is built on comes from getting fully submerged.

HOW TO CHOOSE

Which one should you use?

Choose an ice bath if…

  • Your main goal is post-training muscle recovery and reduced soreness
  • You want the deeper, more evidence-backed cold load
  • You want to pair cold with a sauna for contrast therapy
  • You like being able to control your depth and exit any time

Cryotherapy may suit you if…

  • You want a fast, dry cold hit with no changing into swimwear
  • You dislike full water immersion
  • You are using it mainly for the nervous-system "buzz" and alertness
  • Convenience matters more than maximum cold load

SAFETY

Both share similar contraindications

Cold water immersion and whole-body cryotherapy are both unsuitable for people with cardiovascular disease, uncontrolled high blood pressure, Raynaud's disease, epilepsy or who are pregnant. If you have a relevant medical condition, consult your GP before using either. RE:UP staff screen all first-time visitors for contraindications before their session. Cold therapy is for recovery, not a medical treatment.
