The “sauna culture” has a strong following in Japan, and there are many sauna facilities that are particularly popular among sauna enthusiasts.
In this article, we’ll delve into popular facilities and basic information about saunas.
Why not give saunas a try?
What is a Sauna?
A sauna is a type of “steam bath” that originated in Finland.
Inside the sauna room, there is a stove piled high with stones.
The stove is heated, and water is poured over the stones to create steam, which adjusts the temperature and humidity inside the room.
The temperature inside the sauna room is typically between 70°C and 110°C.
The heat promotes sweating, which is believed to improve blood circulation and metabolism, contributing to better health.
What are sauna services?
Some saunas offer unique services that enhance the sauna experience.
Two of the most well-known services are “Löyly” and “Aufguss.”
Löyly involves pouring aromatic water or plain water over heated sauna stones to create steam, which raises the temperature inside the sauna.
This service can be performed by sauna staff at regular intervals, or in some places, guests can pour the water themselves in a style known as “self-Löyly.
” However, it’s important to be cautious when doing it yourself, as excessive heat can be uncomfortable for others.
Aufguss is a practice that follows Löyly, where the steam created is fanned with a towel to distribute the heat more evenly.
This service is usually performed by sauna staff and is popular among sauna enthusiasts.

Benefits of Saunas
Relief from Fatigue, Shoulder Stiffness, and Lower Back Pain
Entering a high-temperature sauna increases blood flow to about twice the normal rate.
Improved blood circulation ensures oxygen reaches the entire body, and fatigue substances are secreted with sweat, leading to potential fatigue recovery.
Additionally, the increased oxygen supply helps alleviate nerve-related symptoms like shoulder stiffness and lower back pain.
Normalizes Blood Pressure
Although blood pressure temporarily rises immediately after bathing, entering a sauna causes blood vessels to dilate, lowering blood pressure.
However, this is a temporary effect and does not cure hypertension, so those with high blood pressure should seek treatment.
Calms the Nervous System
Slowly entering a low-temperature sauna has a calming effect on the body.
This natural relaxation mode helps you achieve a deep sleep after a sauna session.
If you often feel stressed, try relaxing in a low-temperature sauna.
Cleanses Sweat Glands and Sebaceous Glands
The rise in body temperature during a sauna session causes sweat to be released from sweat glands all over the body.
Excess oil is expelled from sebaceous glands in the pores, and strong odors are released from apocrine glands, enhancing the function of sweat glands and cleansing the skin and subcutaneous tissues.
As a result, the sweat you produce after a sauna session is usually smooth and less odorous.
Achieving Balance in the Sauna
A sauna is not just a place to refresh yourself; did you know that mastering the sauna can lead to a pleasure you have yet to discover?
The Enchanting State of Sauna Trance
As you get used to the sauna and repeat the cycle of sauna → cold bath → rest, your blood and oxygen circulate through your body and brain, leading to a “deep relaxation state.”
This trance-like pleasure experienced in the sauna is referred to as “totonou” among sauna enthusiasts.
To enter this trance state, it is recommended to repeat the cycle of “5-10 minutes in the sauna → cold bath → drink water and rest” about five times.
For those not accustomed to cold baths, it is recommended to extend the sauna time to 10 minutes.
Things to Be Careful About When Using a Sauna
A sauna is not something you can use at any time.
Especially high-temperature saunas can put a strain on your body, so avoid using them in the following situations:
Avoid After Drinking Alcohol
Alcohol and saunas do not mix!
Due to the diuretic effect of alcohol, you are more likely to become dehydrated than usual.
Entering a sauna after drinking can lead to severe dehydration.
Because of the potential life-threatening risks, most sauna facilities prohibit the use of saunas after drinking alcohol.
Avoid When Feeling Unwell or If You Have High Blood Pressure
Saunas are a no-go when you’re feeling unwell!
Additionally, if your blood pressure is 160/100 mmHg or higher, entering a high-temperature sauna increases the likelihood of health issues or accidents by more than three times.
Summary
Sauna facilities are gaining popularity not only among sauna enthusiasts but also among the general public.
Recently, the increase in stylish facilities has made saunas popular among younger people and women as well.
Each sauna facility has its own unique features, so sauna hopping is highly recommended.
Find your favorite sauna and experience the sauna trance state!
