Sauna – Not Just Relaxation, but a Protocol for More Health, Energy, and Vitality
At Synergy Club, we believe recovery isn’t just an add-on to training – it’s an equal part of the journey toward health, strength, and longevity.
One of our favorite and most effective tools is sauna – a simple yet powerful method that combines heat, rest, and controlled stress to benefit both body and mind.
Many people see sauna as “just sitting in heat.” But the effects go much further. Regular sauna use has been shown to improve cardiovascular health, strengthen immunity, speed up post-workout recovery, lower stress, and help the body flush out toxins. On a cellular level, it stimulates the production of heat-shock proteins, which protect and repair our cells – a principle used in many longevity protocols.
Did you know that regular sauna use lowers the risk of all-cause mortality? One study of 2,300 Finnish men over ~20 years found that frequent sauna sessions (4–7 times per week) correlated with a much lower risk of death from all causes, including cardiovascular disease:

- 1× per week: ~49% mortality
- 2–3× per week: ~38%
- 4–7× per week: ~31%

Finnish and Infrared Sauna – Two Paths, One Goal
At Synergy, we offer both Finnish and infrared saunas – each with unique benefits.
Finnish sauna: The classic. Dry air, temperatures often above 80 °C, and an intense whole-body heat. Heart rate rises, blood vessels expand, circulation speeds up – similar to light aerobic activity. This sauna is excellent for cardiovascular support, immunity, and mental clarity after a demanding day.
Infrared sauna: Works differently – instead of heating the air, it uses infrared light that penetrates deeper into tissues at a lower temperature (around 50–60 °C). Gentler, yet highly effective for muscle and joint recovery, pain relief, and reducing fatigue. Because of the lower heat, it’s also ideal for those who can’t tolerate high temperatures, or for post-training recovery.

When to choose which sauna?
After heavy strength or endurance training, the body is already stressed and in recovery mode. Infrared sauna offers a milder, targeted heat that improves circulation without extra load on the cardiovascular system.
On rest days or after light activity, Finnish sauna is an excellent choice. The intense heat triggers strong vascular and hormonal responses that benefit heart, vessels, and immunity.
Both sauna types also support mental health – lowering stress hormones and improving sleep quality.

How to sauna properly
Sauna use has its own rules, which are worth following to ensure the best possible effect and safety.
- No swimwear: Not just tradition, but function and hygiene. Wet swimwear blocks sweat evaporation and irritates the skin. Always use a towel or sheet to sit on.
- Duration: Start with 10–15 minutes, then extend as you feel comfortable. In Finnish sauna, 2–3 heat/cool cycles are common. In infrared sauna, one longer 20–30 minute session is usually enough.
- Between cycles: Cool down – with a cold shower or cooling bucket in the wellness showers. Then rest in the Synergy wellness lounge before re-entering.
- Before & after: Don’t go in hungry or right after a heavy meal. Stay well hydrated before and after – ideally with clean filtered water or electrolytes available at reception.
- After sauna: Rest. Give your body time to normalize temperature and heart rate.

When to avoid sauna
Sauna isn’t always suitable – for example, during acute illness, fever, unstable blood pressure, or certain cardiovascular conditions. Pregnant women should consult their doctor first. The golden rule: listen to your body. If you don’t feel well, skip the sauna.

Sauna as part of longevity
Sauna has become a key element in many modern longevity protocols – programs designed to extend healthy, active years. The reason is simple: repeated heat exposure stimulates processes that improve stress resilience, support metabolic health, and enhance recovery.
At Synergy Club, we see sauna not just as relaxation, but as a targeted tool – just like training or nutrition. The right sauna type, interval, and frequency can significantly influence your fitness, immunity, and energy.
