Saunas in winter

The cold season is the best time for a sauna. The contrast between heat and cold feels particularly intense.

Why winter saunas are so good for you

A stronger immune system

In winter, we are more prone to colds. Regular sauna sessions strengthen the immune system through the alternation between hot and cold.

Better cooling down

What is a struggle in summer happens naturally in winter: cooling down. A quick trip outside replaces the plunge pool.

Mood booster

The dark season can dampen the mood. The warmth and relaxation of the sauna act as a natural antidepressant.

Outdoor saunas: The highlight

Switzerland has wonderful outdoor saunas with mountain views. The experience: 90°C in the cabin, then out into the snow.

Our favourites for winter saunas:

  • Outdoor saunas with mountain views
  • Saunas right by the lake (with ice-bathing option)
  • Alpine saunas with wood-fired heating

Tips for the winter sauna

Before the sauna session:

  • Warm up properly (don’t start with cold feet)
  • Have warm drinks ready
  • Don’t forget your bathrobe and slippers

When cooling down:

  • Rolling around in the snow? Only for the hardy!
  • Walking barefoot through the snow is more effective than a plunge pool
  • Don’t stay outside too long
  • Warm up properly afterwards

After the sauna:

  • At least 30 minutes’ rest
  • Warm tea or water
  • Return to the cold gradually

Take care in sub-zero temperatures

In extreme cold (below -10°C), you should take care:

  • Don’t go outside with wet hair
  • Keep the cooling-off period shorter
  • Pay attention to your body’s signals

The perfect winter sauna experience

Our recipe for the ideal winter’s day:

  1. Arrive in the early afternoon
  2. First sauna session with an infusion
  3. Cool down in the snow or plunge pool
  4. Relax with a mountain view
  5. Second sauna session
  6. Cool down, then hot tea
  7. Third sauna session at sunset
  8. Wind down slowly

The combination of sauna, snow and winter scenery is unbeatable. Give it a go!
