Cold plunge: what does the research say?

A refreshing approach to recovery.

After a demanding workout, feeling ready for what’s next matters. Research in physically active participants suggests cold-water immersion can reduce next-day soreness and improve perceived recovery after high-intensity exercise. Results vary with the activity and approach.

A closer look at that refreshed feeling.

Early research offers a promising reason to be curious. In one small study, healthy adults reported feeling more alert, active and inspired after cold-water immersion. It was a short-term, before-and-after study without a comparison group, so there’s still more to learn.

Curious about mood, focus and body chemistry?

Andrew Huberman discusses how cold exposure may relate to mood, focus and dopamine. The physiological study below also explores changes in blood dopamine and noradrenaline during prolonged cold immersion. These are starting points for understanding the body’s response, not proof of a lasting hormone reset or a promise about a brief Vitality session.

• Less soreness after a demanding workout →

  Moore et al., 2022. A review of 52 studies found less soreness and better perceived recovery 24 hours after high-intensity exercise compared with passive recovery. Findings apply to physically active participants; approaches and results varied.

• Feeling more alert and uplifted →

  Yankouskaya et al., 2023. In a small study, 33 healthy adults reported feeling more alert, active and inspired after a five-minute immersion at 20°C. With no comparison group, this is an encouraging early finding about short-term feelings.

• Huberman Lab: mood, focus and dopamine →

  Andrew Huberman explores cold exposure, mood, focus and dopamine in this accessible guide. It is expert discussion, not a clinical trial or evidence of results from a Vitality session.

• Exploring the body’s response to cold →

  Šrámek et al., 2000. Researchers measured increased blood dopamine and noradrenaline during a one-hour immersion at 14°C in young men. This helps explain the body’s response to cold; it does not establish lasting hormone changes or the effects of a brief session.

Put your safety first.

Cold water can sharply affect breathing, heart rate and blood pressure. Check with your clinician first if you have a medical condition or concerns, especially heart or circulation issues. Follow facility safety instructions and stop if you feel unwell.
