When the sun is blazing outside and temperatures climb towards 30°C, the idea of voluntarily sweating in a sauna seems downright insane. But what if that’s exactly what your body (and mind) needs?
Hotter than hot – why go to the sauna in summer?
In summer, we seek cool relief – iced lemonade, air conditioning, or a swimming pool. The thought of entering a sauna where it’s over 90°C sounds like a health hazard. But reality might surprise you.
Regular sauna sessions aren't just a winter thing. In fact, they're a powerful tool for prevention and recovery all year round. Scientific studies (such as those from the University of Kuopio in Finland) show that regular sauna-goers have a lower risk of heart disease, better mental resilience, and faster recovery – even (or especially) in summer.
Summer sauna as a resilience workout
Being in a sauna triggers controlled "heat stress", prompting the body to adapt. It activates the production of so-called heat shock proteins – defensive molecules that repair and protect cells. Sauna use also increases heart rate, dilates blood vessels, and improves circulation throughout the body.
And here’s the point: if your body can handle high heat in the sauna, it will better cope with summer heat outdoors. You train your thermoregulation, strengthen your heart and blood vessels – and enjoy deep relaxation often missing in scorching summer days.
Take inspiration from Finland
In Finland, people use saunas all year round – regardless of the weather. It's completely normal to enjoy a sauna in summer and then jump into a lake. The contrast between heat and cold acts like a natural vascular massage, enhancing blood flow and vessel flexibility.
Finnish tradition shows that the body doesn't switch to "sauna mode" by season, but by frequency. The more often you visit the sauna, the better your body responds – and summer is the perfect time to build the habit.
How to sauna smart and safe in summer
Let’s face it – summer is extreme. Your body dehydrates faster than you can replenish. If you decide to sauna in summer, follow these tips:
- Stay hydrated. Drink at least half a liter of water or mineral water before entering. Keep drinking between sessions.
- Shorten your sessions. In summer, 5–8 minutes may be enough – and always listen to your body.
- Cool down wisely. You don’t have to plunge into an ice bath – a lukewarm shower is just fine.
- Choose gentler sauna types. Tropical, herbal, or salt saunas are milder, yet effective.

“I never thought I’d go to the sauna in June. But it was one of the most pleasant evenings. The natural scents in the herbal sauna and then a dip in the cold pool? A perfect reset,” says Petra from Brno.
Lukáš, training for a half marathon, adds: “Summer recovery in a Finnish sauna helps me more than massages. I recover faster and sleep more deeply afterwards.”
