Long before recovery studios existed, before sports science labs and wearable trackers, people understood something simple:
Heat heals.
Sauna bathing dates back more than 2,000 years and is most famously rooted in Finland, where it remains a weekly ritual embedded into daily life. In Finnish culture, the sauna was not a luxury. It was a necessity — used for physical cleansing, emotional release, recovery, and even childbirth.
Similarly, ancient Roman bathhouses were central to social and physical wellbeing. These spaces combined hot rooms, cold plunges, and rest areas — an early form of what we now call contrast therapy.
Across cultures and centuries, humans returned to heat again and again.
Now, modern science confirms why.
What Happens in the Body During Sauna Use?
When you step into a sauna — whether traditional or infrared — your body responds immediately.
1. Core Temperature Rises
Your body temperature increases, triggering thermoregulation. This stimulates sweating and increases heart rate.
In fact, heart rate in a sauna can rise to 100–150 beats per minute — similar to moderate cardiovascular exercise.
2. Blood Vessels Expand (Vasodilation)
Heat causes blood vessels to widen, increasing circulation. This improved blood flow:
Delivers oxygen and nutrients to muscles
Assists in removing metabolic waste
Reduces muscle tension
Supports cardiovascular health
For strength-focused gym members, this means improved muscle recovery after intense sessions.
For mums juggling mental and physical fatigue, improved circulation supports energy and reduces that heavy, stagnant feeling.
Sauna and Cardiovascular Health
One of the strongest bodies of research on sauna use comes from Finland.
Large longitudinal studies have found that individuals who use sauna regularly (4–7 times per week) show:
Reduced risk of cardiovascular disease
Improved blood pressure regulation
Lower systemic inflammation
Improved overall longevity markers
Heat exposure acts as a mild stressor — and when repeated consistently, the body adapts positively.
Just like strength training builds stronger muscles, repeated sauna use builds a more resilient cardiovascular system.
Inflammation and Muscle Recovery
When you train — especially strength and conditioning — your muscles experience microtears.
Inflammation is part of the repair process.
Sauna supports this process by:
Increasing blood flow to damaged tissue
Supporting nutrient delivery
Reducing excessive inflammatory markers
This is why many athletes incorporate sauna into their weekly programming — not just for relaxation, but for measurable recovery benefits.
At Aura recovery studio in Engadine, this becomes especially valuable for members training multiple times per week.
Sauna and the Nervous System
Perhaps the most underrated benefit of sauna is its impact on the nervous system.
Modern life keeps many women — especially mums — in chronic fight-or-flight mode.
When you sit in a sauna:
External stimulation reduces
The body is forced to slow down
Parasympathetic (rest-and-digest) activation increases post-session
Over time, regular heat exposure improves stress resilience.
You become better at switching between activation and recovery.
The sauna becomes more than recovery. It becomes emotional regulation.
Infrared vs Traditional Sauna
Traditional sauna heats the air.Infrared sauna heats the body directly using light waves.
Both increase circulation and promote sweating, but infrared tends to feel more tolerable at lower temperatures — making it ideal for beginners.
We explore the detailed comparison in our Infrared vs Traditional Sauna blog.
Sauna and Detoxification
While the body primarily detoxifies through the liver and kidneys, sweating does support elimination of certain trace elements and toxins.
More importantly, sauna supports detox indirectly by:
Improving circulation
Enhancing lymphatic movement
Supporting stress reduction
When the nervous system calms, detoxification pathways function more efficiently.
Practical Sauna Recommendations
For general health: 2–4 sessions per week15–25 minutes per session
For strength athletes: Post-training or on recovery days
For mums: During high stress weeks. Before bed to improve sleep
Hydration is essential.
Why Sauna Is Strongly Recommended
Sauna remains one of the most researched and consistently recommended recovery modalities because it influences:
Cardiovascular health
Inflammation
Muscle recovery
Stress resilience
Sleep quality
It’s simple.It’s accessible.It’s effective.
And when combined with cold exposure (contrast therapy), its benefits multiply.
Heat has always healed.
Now we understand why.
