Feeling brave after your Ice Bath? Thinking of jumping straight into a hot shower or a sauna? Short answer: Yes to the sauna, no to the hot shower – and there’s some science-backed fun behind it! Read on to find out how your Cold Plunge Tub and Ice Bath Tub can unlock serious wellness perks when paired with heat the right way.

The "Yes" and "No": Sauna vs. Hot Shower
After a Cold Plunge or Ice Bath Tub session, many people instinctively reach for heat. But should that heat come from a sauna or a hot shower?
Yes – the sauna is generally recommended as it promotes gradual rewarming and deeper relaxation.
No – a hot shower, although tempting, can shock the system by forcing rapid rewarming in a way that disrupts the body's natural process.
Choosing the right follow-up to your Cold Plunge Tub session makes a noticeable difference to recovery and overall benefit.
Historical Context: The Nordic Cycle
The combination of hot and cold therapy isn't new. In fact, it has roots in Nordic and Scandinavian traditions.
These cultures have used sauna and ice baths in cycles – known as the "Nordic Cycle" – for centuries.
Today, this practice is gaining popularity across wellness circles globally, and it’s no wonder.
Alternating between hot and cold offers a natural, invigorating way to support both mind and body.
Understanding the Body's Response: Why Sequence Matters
Cold Plunge: Vasoconstriction and Initial Shock
When you step into a Cold Plunge Tub, your blood vessels constrict – a process called vasoconstriction.
This helps preserve core temperature but also gives your body a powerful jolt, increasing heart rate and triggering an endorphin rush.
As you leave the cold water, the body gradually begins to rewarm itself.
This natural recovery is essential to avoid shock or unnecessary strain.
Sauna: Vasodilation and Accelerated Rewarming
Sauna heat causes vasodilation – where blood vessels widen, promoting circulation and rewarming from within.
This process helps regulate body temperature more safely after a Cold Plunge.
Increased blood flow delivers oxygen and nutrients to muscles and tissues, helping speed up recovery.
The sauna complements cold exposure perfectly by easing tension and restoring comfort after that icy shock.
The Pitfalls of a Hot Shower After Cold Plunge
A hot shower may feel appealing, but it’s not ideal immediately after a cold immersion.
Hot water can force blood away from the extremities and rush it toward the core too quickly.
This sudden shift can cause discomfort, dizziness, or even increase the risk of shock for some people.
Also, it may disrupt the beneficial cascade of hormonal responses and temperature regulation started by the cold plunge.
Maximising Benefits and Ensuring Safety
Enhanced Circulation and Cardiovascular Health
The combination of hot and cold acts like a natural vascular workout.
Blood vessels contract and dilate repeatedly, improving blood flow and possibly reducing blood pressure over time.
This "pumping" effect may help keep your cardiovascular system strong and responsive.
Accelerated Muscle Recovery and Reduced Soreness
Switching between heat and cold helps flush out waste products like lactic acid.
It also reduces inflammation, aiding in muscle recovery.
This is why many athletes swear by the cold plunge and sauna combo.
Boosted Immune System
Consistent use of hot and cold therapy may stimulate white blood cell production.
This supports immune function and helps the body defend itself more effectively.
It’s a natural way to build resilience.
Improved Mental Well-being: Stress Reduction and Mood Enhancement
Contrast therapy encourages the release of endorphins, dopamine, and norepinephrine.
These chemicals are known to lift mood, enhance focus, and combat stress.
It’s like a reset button for your brain after a long day.
Detoxification and Skin Health
Saunas promote sweating, helping remove toxins through the skin.
Afterwards, a cold plunge can close pores and improve skin tone.
Together, they support both internal cleansing and outward glow.
Practical Application: Tips for Your Sauna and Cold Plunge Routine

Optimal Timing and Duration for Each Session
-
Sauna: 15–20 minutes at around 80–100°C
-
Cold Plunge: 1–3 minutes at 10–15°C
-
Breaks: 5–10 minutes rest between cycles
Start slow and adjust based on your comfort.
Hydration is Key
Drink water before, during, and after your session.
Sweating and cold exposure can both dehydrate you without obvious signs.
Listening to Your Body and Gradual Progression
Don’t rush into long sessions.
Begin with shorter durations and increase only as your body adapts.
If you feel faint, dizzy, or overly chilled, take a break.
Important Considerations and Who Should Consult a Doctor
Pre-existing Health Conditions and Medical Advice
If you have heart issues, high blood pressure, or any chronic health condition, speak with a healthcare professional first.
Contrast therapy may not be suitable for everyone.
Avoiding Alcohol
Alcohol and extreme temperatures don’t mix.
Avoid drinking before or during your sauna or Cold Plunge session.
It can impair judgment and increase risk of accidents or dehydration.
Signs to Watch For and When to Stop
Look out for shivering, dizziness, nausea, or numbness.
These may be signs you’ve pushed too far and need to stop immediately.
Always respect your limits.
