Why Saunas Are Best in Winter | The Appeal of Washinmura Sauna with Minamiboso's Outdoor Air and Mountain Spring Water Baths

Winter is said to be the easiest season to reach a state of "Totou" (deep relaxation) throughout the year. This is because the cold outdoor air, clear atmosphere, and gentle temperature differences maximize the effects of a sauna.

At Washinmura, nestled in the rural landscape of Futtsu City, Minamiboso in Chiba Prefecture, alongside winter traditions like kotatsu, mandarin oranges, hot pots, and interacting with cats, **the winter sauna becomes the highlight of the stay**.

In this article, we will thoroughly introduce **the charm of winter saunas, the characteristics of Minamiboso's outdoor air bathing, and why the Washinmura sauna is ideal for winter**.

① Overwhelming Refreshment Created by Temperature Differences

In the flow of Sauna (heat) → Cooling → Outdoor Air Bathing, the most important thing is **to thoroughly cool the body down once**. In winter, the outdoor air itself acts as a natural cooldown, providing an ideal environment where: - There is no feeling of suffocation - There is no stinging pain on the skin - It is easy to take deep breaths

The winter in Minamiboso is "cold but not too cold." This maximizes the benefits of a winter sauna.

② The Winter Air is Clear

Winter, with its low humidity and clear air, is a season where breathing during an outdoor air bath feels exceptionally good. The sensation of air smoothly reaching deep into the lungs is unique to winter. It's a feeling that cannot be experienced in urban saunas.

③ The Parasympathetic Nervous System Takes Over Instantly

The cold winter air tightens the body, and during the subsequent rest, the parasympathetic nervous system quickly becomes dominant, leading to: - Deep calmness - High-quality sleep - Clarity of thought A characteristic of winter saunas is the **significant relaxation effect on both mind and body**.

2. Reasons Why Minamiboso's Outdoor Air Bathing "Feels Good"

① A "Pain-Free Cold" Even in Winter

Minamiboso has a mild winter due to the influence of the Kuroshio Current. Because the temperature doesn't drop too low, outdoor air bathing is incredibly comfortable. - Not freezing cold - Air that is gentle on the skin - Allows for prolonged outdoor air bathing The ideal outdoor temperatures for a winter sauna are naturally available.

② The Profound Quietness of a Winter Rural Landscape

Takamizo in Futtsu City, where Washinmura is located, is an area surrounded by rural landscapes. In winter, there are fewer sounds, with only the wind, bird calls, and the crackling of firewood echoing. The quiet environment helps the parasympathetic nervous system function, elevating the quality of the outdoor air bath.

③ The Winter Starry Sky is Especially Beautiful

In winter, when the air is clear, the visibility of the starry night sky is remarkably better. The flow of Sauna → Outdoor Air Bath → Stars is a luxury unique to winter.

3. The Appeal of Washinmura Sauna

**① Features a Cold Bath Using "Clean Water Derived from a Mountain Water Source"**

The cold bath at Washinmura uses **soft water derived from a mountain water source** managed by a local waterworks union. This water has characteristics that make it highly compatible with saunas: * It comes from a different route than general urban water supplies (mountain source) * It is safely purified as drinking water * In winter, it reaches an ideal temperature that is "cold but not painful"

② **Outdoor Air Bathing is Good, but Adding a Cold Bath Makes Relaxation Unparalleled**

**Out**door air bathing alone is pleasant enough. However, lightly entering the cold bath completely changes the way you relax. * The mind becomes clear * Blood circulation changes instantly * The moment you start resting, the body feels surprisingly light * The winter water temperature is just right, providing a "not too cold" and "tightening pleasantness."

③ **Excellent Compatibility with Löyly**

**Wa**shinmura sauna allows for Löyly. The steam spreads thoroughly in the dry winter air, gently warming the core of the body. Löyly → Cold Bath → Outdoor Air Bath This sequence is perfected under the best conditions in winter.

④ **Combining Kotatsu, Hot Pot, and Cats Creates the "Perfect Winter Experience"**

**After** relaxing in the sauna, returning to the kotatsu, eating mandarin oranges, gathering around a hot pot, and spending time with cats. Washinmura is the only place where these four elements come together. An optimal cycle for a winter stay naturally emerges.
