There’s something deeply satisfying about stepping out of a sauna – skin feels warm,
muscles loose, mind clear. But beyond simply feeling good, saunas are receiving increasing recognition and attention for their health benefits.

So, is this just a pleasant ritual… or something worth weaving more deliberately into your routine?

A Brief History: Where It All Began

Saunas have been used for thousands of years, most famously in Finland, where they are
deeply embedded in daily life and culture. Originally, they weren’t luxury spa experiences – they were practical, communal spaces used for bathing, relaxation, and even childbirth.

Fast forward to today, and modern research is beginning to catch up with what these
cultures have long intuitively understood for centuries.

What Does the Science Say? Who Might Benefit — and Why

Regular sauna use has been linked to several measurable health benefits. The key driver?
Controlled heat exposure, which places the body under mild stress – triggering adaptive
responses.

1. Cardiovascular Health

• Heat causes blood vessels to open, increasing blood flow and temporarily lowering blood pressure.
• Repeated exposure has been shown to improve overall cardiovascular resilience – helping the heart cope better when it has to work harder.

2. Muscle Recovery & Pain Relief

Increased circulation helps deliver oxygen and nutrients to tissues, which can …

• Reduce muscle soreness after exercise
• Ease joint stiffness (particularly in conditions like osteoarthritis)
• Promote relaxation of tight muscles

… creating a more favourable environment for recovery (and often making you feel a little
less creaky getting up afterwards).

3. Stress & Mental Health

Saunas activate the parasympathetic nervous system (your “rest and digest” mode), while also increasing endorphin levels. This combination can:

• Reduce stress
• Improve sleep quality

There’s something remarkably powerful about enforced stillness – no phone, no distractions.

4. Metabolic & Immune Effects

Heat exposure increases heart rate and sweating, mimicking some aspects of moderate exercise. Potential benefits include:

• Improved insulin sensitivity (-> better blood sugar control)
• Temporary increase in metabolic rate (-> a small increase in calories burnt)
• Stimulation of heat shock proteins (which help protect cells from stress)

There’s also some evidence suggesting fewer respiratory infections in regular users.

Where Saunas Are Not the Answer (and When to Be Careful)

This is where it’s important to stay mindful – saunas are supportive, not curative.
They are NOT a treatment for:

• Active infections (e.g. fever, acute illness)
• Cancer
• Rapid or sustained weight loss

Use caution if you have:

• Uncontrolled high or low blood pressure
• Significant heart conditions (e.g. unstable angina)
• Pregnancy (especially early stages)
• A tendency to faint or feel lightheaded
• Dehydration (hence why alcohol and saunas are also a poor combination)

If you fall into any higher-risk group, always check with a healthcare professional.

Contrast Therapy: Hot, Cold… Repeat

Contrast therapy is the intentional alternation between hot and cold – which is why saunas are often coupled with cold plunges, cold showers, or brisk ocean dips.

This rapid switching creates a kind of “vascular workout”:

• Heat → blood vessels open
• Cold → blood vessels narrow

Potential benefits:

• Reduced muscle soreness
• Improved circulation dynamics
• Increased energy, alertness and mental clarity

A simple approach:

• 10–15 minutes sauna
• 30–90 seconds cold
• Repeat 2–3 cycles
  (The first cold plunge is always the hardest.)

Saunas in the Spotlight: Prescribed on the NHS?

Recently, saunas have received increased media attention, with discussion around whether they could one day be “prescribed” through the NHS.

The idea stems from growing evidence around cardiovascular and mental health benefits, alongside the relatively low-risk nature of sauna use when done appropriately.
It’s an interesting shift – recognising lifestyle-based interventions not just as “nice extras,” but as meaningful contributors to health. A small but notable move toward more
preventative and supportive care.

Sauna vs Steam Room: Does It Matter?

While often grouped together, saunas and steam rooms are quite different environments.

Sauna (Dry Heat)

• Temperature: 70–100°C
• Low humidity
• More intense heat exposure

Best for:

• Cardiovascular conditioning
• Muscle relaxation
• Heat adaptation

Steam Room (Humid Heat)

• Temperature: 40–50°C
• High humidity (near 100%)
• Feels deceptively gentler but can still be intense

Best for:

• Airway hydration (helpful for congestion)
• Skin hydration
• Those who find dry heat uncomfortable

Saunas tend to produce stronger cardiovascular and metabolic effects due to higher heat.

Steam rooms may feel more comfortable and can be helpful for respiratory symptoms – but their whole-body effects are likely less pronounced.

So … Where Do Saunas Fit In?

Saunas aren’t a miracle cure – but they’re far from meaningless. Used regularly and sensibly, they can:

• Support cardiovascular health
• Aid sports recovery
• Provide a structured space to slow down

Perhaps just as importantly, they create time. And in a world that tends to favour complexity, there’s something refreshingly simple about that.
