Cold water is having a global moment, and Finland's centuries-old tradition of avantouinti — winter swimming in a hole cut into the ice — is suddenly trending with travellers in 2026.
What is avantouinti?
Avantouinti literally means "ice-hole swimming". A short dip — often less than a minute — into freezing water, traditionally combined with a sauna session. It's a normal part of life for many Finns, and there are public ice-swimming spots in cities across the country.
The health benefits people talk about
- Improved circulation through cold exposure
- Reported boost in mood and energy
- Better sleep and stress recovery for regular practitioners
- Combined with sauna, a contrast-temperature wellness ritual
Research is still developing. For most healthy adults a short, supervised cold dip is safe, but cold-water immersion is not risk-free.

How to try it safely as a traveller
- Use an official ice-swimming spot with a ladder, warm changing facilities and staff.
- Never swim alone in cold water.
- Keep dips short — often 10–30 seconds is enough.
- Warm up properly afterwards, ideally in a sauna.
- Avoid alcohol before swimming.
Where to try avantouinti in Finland
Helsinki, Tampere, Turku, Oulu and many smaller towns have public winter swimming clubs and sauna venues that welcome travellers. Most offer day passes — no membership required.
What if something goes wrong?
If you feel chest pain, dizziness or difficulty breathing during or after a cold dip, seek medical attention. In Finland (and the EU) the emergency number is 112. For non-emergency care — like checking blood pressure or getting cleared to try it — Health4Travel can connect you with English-speaking GPs and telehealth providers in Finland.
