Getting Started with Cold Therapy

Cold water immersion is one of the most studied tools in recovery and performance. It's also one of the most misunderstood. Here's what you actually need to know before you begin.

What temperature should I start at?

Don't chase the cold. Starting at 15°C is cold enough to trigger the physiological benefits: adrenaline release, vasoconstriction, and activation of the nervous system. Work your way down as your body adapts.

• Beginners: 57–61°F (14–16°C)
• Intermediate: 50–57°F (10–14°C)
• Advanced: 46–50°F (8–10°C)

How long should I stay in?

Start with 2–3 minutes and build to 5–10 minutes over a few weeks. Research suggests benefits plateau around 10–15 minutes, so longer isn't necessarily better.

How often should I plunge?

3–5 times per week is optimal for most people. Daily plunging is possible, and many experienced practitioners prefer it, but rest days give your nervous system time to integrate the benefits.

What to expect in your first few sessions

• The first 30–60 seconds are the hardest. Your body will want to gasp and tense. Focus on slow, controlled breathing.
• After the initial shock settles, many people experience a calm, focused state while still in the water.
• The afterglow (elevated mood, clarity, warmth) typically lasts 2–4 hours post-session.

Tips for your first plunge

• Don't go alone your first time.
• Have warm, dry clothes ready to change into immediately after.
• Avoid eating a heavy meal within an hour of plunging.
• Breathe through your nose. This activates the parasympathetic nervous system and counteracts the gasp reflex.
