Sauna Before or After a Workout? What the Science Actually Says

Athletes and gym-goers across the Okanagan are asking this question more often as sauna culture grows. Should the sauna come before or after training? And does the cold plunge go before or after the sauna?

Here is what the evidence says, and how to structure your sessions for maximum benefit.

The Case for Sauna After a Workout

For most people, most of the time: sauna after is better.

Here is why.

Recovery acceleration. A workout creates microscopic muscle damage that your body needs to repair. This is how muscles grow stronger. Sauna after training accelerates this process significantly. The heat triggers heat shock proteins that repair damaged proteins in your cells. Growth hormone spikes (up to 200–300% above baseline in some protocols) support muscle synthesis. Circulation is increased, flushing metabolic waste from tissues.

No performance impairment. Sauna before training creates cardiovascular stress, including elevated heart rate, dehydration, and body temperature increase, before you even begin your workout. This can reduce strength output and endurance performance, particularly in the first half of a training session.

Glycogen considerations. Training depletes muscle glycogen. Sauna after training allows you to refuel first, so the heat stress happens to a body that is managing recovery rather than competing with fuelling for performance.

When Sauna Before Training Makes Sense

There are scenarios where sauna pre-workout is beneficial:

Warming up in cold weather. A short sauna exposure (5–10 minutes) before training in cold conditions can warm the muscles and connective tissue, reducing injury risk. This is a different use case from a full session.

Heat acclimatisation for endurance athletes. Deliberate heat training, meaning training in or near heat stress conditions, can improve performance in warm-weather events by expanding plasma volume and improving thermoregulation. This is a specific protocol, not the standard recommendation.

Mental preparation. Some athletes find the focus and arousal that follows heat exposure to be a useful pre-training state. If a short sauna sets your mind right before a session, that is a valid reason to use it.

The Cold Plunge: After the Sauna, Not Before Training

If you are doing contrast therapy around a workout, the sequence matters.

For recovery: Train → Sauna → Cold plunge. The sauna promotes blood flow and tissue repair. The cold plunge reduces inflammation and soreness. Together they produce a significantly faster recovery than either alone.

One important nuance: If your primary goal is muscle hypertrophy (building muscle size), emerging research suggests that immediate cold water immersion after training may blunt some of the inflammation that is part of the signalling pathway for muscle growth. If building size is your primary goal, wait 2–4 hours after training before cold plunging, or cold plunge before your workout instead.

For general fitness, health, and recovery, the sequence of training, then sauna, then cold plunge is optimal.

A Practical Protocol for Okanagan Athletes

If you are using Sweat Culture as your recovery tool:

1. Train: your workout, run, bike, whatever your practice is.
2. Drive to Sweat Culture (20–25 min from Kelowna, 10–15 min from West Kelowna).
3. Sauna round 1 (15–20 min). Let the heat shock proteins go to work.
4. Cold plunge (1–3 min in Okanagan Lake).
5. Fire pit recovery (5–10 min).
6. Sauna round 2 (10–15 min).
7. Cold plunge round 2.
8. Drive home feeling like a different person.

Many of our regulars build this into their weekly training schedule. Sunday morning run club, which starts and ends at Sweat Culture, is the full cycle in one session.
