Should You Sauna or Cold Plunge First?

No study has tested whether sauna first or cold plunge first is better for health outcomes, so order comes down to your goal and comfort. The usual approach is sauna, then a short cold plunge, repeated if you like. In one trial, a 90-second 20°C dip between sauna rounds lowered core temperature and heart rate in the second round.¹

Key takeaways

Contrast therapy (alternating hot and cold) has been tested for recovery, but trials rarely compare which came first.²
In a 2026 crossover trial of 16 adults, a 90-second 20°C dip between two 15-minute 85°C sauna bouts left core temperature 0.48°C lower and heart rate 17 bpm lower at the end of the second bout than cooling in air.¹
Sauna followed by 12°C water was well tolerated by 37 men with heart failure, coronary disease, or neither, though cold raised systolic pressure.³
If you strength train, avoid the plunge right after lifting. It reduced muscle gains in a trial.⁴

Does the order of sauna and cold plunge matter?

We found no study comparing sauna-then-cold with cold-then-sauna on health or recovery outcomes. Contrast water therapy, alternating hot and cold water, has been studied. A meta-analysis of 18 trials found it improved soreness and strength loss compared with rest, but not clearly more than other recovery methods, and every trial had a high risk of bias.² Those trials used hot and cold water immersion, not dry-heat saunas, and didn't isolate order.

What the evidence suggests

Order of sauna and cold plunge

Evidence strength: Preliminary

Best-supported finding: Cooling in cold water between sauna rounds lowered heat strain in one small trial, and sauna followed by cold immersion was well tolerated in a small acute study.^{1, 3}
What remains uncertain: Whether order changes any health, recovery, or sleep outcome. No trial has compared the sequences.
Research context: Small acute physiology studies in relatively healthy adults, with cold water at 12 to 20°C.

What these labels mean

Strong: Consistent results across multiple well-designed trials or meta-analyses, in populations similar to the ones described.
Moderate: Several studies point the same way, but with design limits, mixed results, or populations that may not match yours.
Limited: Some human data exists, but it comes from small trials, observational work, or protocols that vary widely.
Preliminary: Mostly animal, mechanistic, or very small human studies. Treat as a hypothesis.

What is the most common order, and why?

Most people go sauna first, then cold, then rest. Heat makes the cold easier to face, and the cool-down ends the session at a comfortable temperature. The 2026 crossover trial supports part of that. Sixteen healthy adults did two 15-minute 85°C sauna bouts, each followed by a 10-minute cooling break in room air, with or without a 90-second dip in 20°C water. With the dip, they finished the second bout at 37.55°C core temperature versus 38.03°C and 108 versus 125 bpm, and said they felt less hot and better able to tolerate the second bout.¹

The water was 20°C, not ice-cold, the dip lasted 90 seconds, and the trial measured heat strain, not health outcomes. It shows that cold between rounds makes a sauna easier. It doesn't show that any order produces a lasting benefit.

Should you ever do cold first?

Some people do, for alertness before work or to warm up afterward. No research supports it as better or worse. One argument for it is that cold raises blood pressure and heart rate on entry, so doing it first, while you're rested, avoids stacking demands. In the heart failure study, systolic pressure fell during the sauna and rose with the cold immersion that followed, and both were tolerated.³ Both orders swing cardiovascular load a lot, and that's a reason for caution.

Suggested order by goal. These are common practices, not research-tested protocols.
Goal	Common order	Why
Relaxation and sleep	Sauna, then a brief cool rinse or short plunge, then rest	Ends warm or calm, and cold between rounds eases heat strain¹
Morning alertness	Short sauna, then a plunge, or a plunge alone	Adults reported feeling more active and alert after cold immersion⁵
Hard non-lifting workout	Either order, with cold at 11 to 15°C for soreness	Modest soreness evidence for cold⁶
Lifting for muscle growth	Sauna after training, plunge on another day or hours later	Cold right after lifting blunted gains in one trial⁴

How long between the sauna and the plunge?

No research gives a number. The trial used a 10-minute cooling break that included the 90-second dip.¹ Many people wait a few minutes in room air until their breathing settles, then enter the water gradually. Time and temperature are covered in our cold plunge duration guide and sauna duration guide.

Frequently asked questions

Is it better to do a cold plunge after a sauna?

It's the most common order, and it made sauna sessions easier to tolerate in one trial.¹ No study shows it's better for long-term health.

How many rounds of sauna and cold should I do?

No researched number exists. The trial that added cold between bouts used two 15-minute sauna bouts.¹ Two or three rounds is common practice.

Should I do a cold plunge before or after a workout?

After a non-lifting workout it's fine. After strength training it may blunt muscle gains, so many lifters wait.⁴ See cold plunge benefits.
