The full breakdown. What it is, why it matters, how to use it.
Cold therapy (ice baths, cold plunges, cold showers) constricts blood vessels, reduces inflammation, and numbs pain receptors. It's excellent for acute injury and reducing DOMS, but chronic overuse may blunt the inflammatory signals that drive adaptation. Use it strategically — not after every training session if hypertrophy is the goal.
Real Questions
Does cold therapy hurt muscle growth?
Possibly if used immediately after every session, since inflammation is part of the growth signal. Save it for when you're very sore or between sessions, not right after training.
How cold and how long?
10–15°C (50–59°F) for 10–15 minutes is the standard protocol. Colder isn't better — it just increases shock risk.
