Hot and cold,
on your terms.
Traditional & infrared sauna, cold plunge, and red light therapy in Boulder — together or on your own.
Sweat · Plunge · Socialize
A space built around hot and cold — and the people you share it with.
Sauna, cold plunge, and red light therapy, designed to do three simple things: help you reset, recover, and spend time together. The goal is unglamorous and exactly the point — for you to leave feeling better than when you arrived.
Step out of the day. Heat, cold, breath, quiet.
A practiced rhythm your body remembers.
Social if you want it. Solo if you don't.
How a visit works
Alternate between hot and cold a few times over about an hour. There's no single correct way to do it — this is just the rhythm most people settle into.
Warm up
Start in the traditional or infrared sauna. Let the heat do its thing — a few minutes is plenty.
Plunge
Into the cold. The first breaths are loud; then it gets quiet. Group or solo — your call.
Repeat
Back and forth, usually three or four rounds over about an hour. You're never on the clock.
Rest
Land in the lounge. Red light, water, a little conversation — or none at all.
Four practices, one rhythm
Better with people. Never required.
A lot of hot-and-cold places feel like a test. Nuvania doesn't. Come with friends and turn it into a ritual, or come alone and disappear into the quiet. Social interaction is encouraged — and completely optional.

First, the obvious questions
Yes — especially. Nuvania is built for people at every stage of comfort with hot and cold, including those who never thought it was 'for them.' Start with the infrared sauna, ease into the cold, and go at your own pace. Our team orients every first-timer.
No. Some people come only for the sauna, only for red light, or only to sit in the lounge. Hot and cold, on your terms — that's the whole idea.
Both. Guided group sessions are encouraged but never required. You can plunge with people or quietly on your own — the space works either way.
Locker rooms, showers, towels, hydration stations, and a lounge to use before or after. Just bring yourself and a swimsuit.
