Refresh your body and mind in a Japanese onsen

Hot springs, or "onsen" as they are called in Japan, are more than just a relaxing retreat. The mineral-rich, warm waters of onsen are known for their numerous health benefits.

From improving circulation to alleviating muscle and joint pain, these natural waters offer a therapeutic escape from the stresses of daily life.

 

But first of all, let's start with the basics!

What are Hot Springs called in Japan?

In Japan, hot springs are known as "onsen." This term refers not only to the natural hot springs themselves but also to the bathing facilities that have developed around them. Onsens are an integral part of Japanese culture and are cherished for their relaxing and healing properties.

What is the most famous Hot Spring in Japan?

One of the most famous hot springs in Japan is Beppu Onsen, located in Oita Prefecture on the island of Kyushu. Beppu is renowned for its variety of hot springs and unique experiences, including the famous "Hells of Beppu," which are a series of vividly colored and striking hot spring pools.

Are Hot Springs Good for Your Health?

Yes, hot springs are considered highly beneficial for health. The warm, mineral-rich waters of onsen can help improve circulation, alleviate muscle and joint pain, and promote relaxation. Here are some of the key benefits of Japanese hot springs:

• Improved circulation : The heat from the onsen water helps to increase blood flow, which can enhance overall cardiovascular health.
• Skin health : The minerals found in onsen water can help treat various skin conditions and improve the overall quality of the skin, leaving it smooth and rejuvenated.
• Muscle and joint relief : The warm water of the onsen is known to relax muscles and soothe joint pain, making it an ideal remedy for those suffering from chronic pain or stiffness.
• Stress relief : The serene environment of an onsen, combined with the soothing warm water, helps reduce stress levels and promote deep relaxation, offering a perfect escape from the hustle and bustle of everyday life.

 

Onsen in Oriental Medicine: The power of wellness and preventive care

Onsen are not designed to "treat" specific diseases, but rather to improve overall health and prevent diseases. The revised therapeutic indications now include conditions such as "functional disorders due to autonomic nervous system instability" and "stress-related disorders (insomnia, depression, etc.)." In other words, it is recognized that onsen can have beneficial effects on mental disorders. Bathing in onsen can offer relaxing and soothing effects.

The therapeutic power of baths and onsen

Why are onsen effective? One might think it's "of course because they contain beneficial components," but various other factors also interact to produce effects. This is called a "complex synergistic effect."

The healing thermal effects of Onsen

The fact that the heat of the water warms the body is called the "thermal effect." This effect promotes blood circulation, and various other effects can be expected. When the body warms up, blood vessels (especially capillaries) dilate, metabolism increases, and the elimination of bodily waste is facilitated. The promotion of blood circulation through the thermal effect is beneficial for the body. It is said that when body temperature drops by 1°C, immunity decreases by 30%, highlighting the importance of keeping the body warm.

Hot water (over 42°C) stimulates the sympathetic nervous system, leading to a state of alertness and excitement. On the other hand, warm water (37-40°C) stimulates the parasympathetic nervous system, which has a relaxing effect and calms the mind. For the Japanese, a water temperature of 42°C is often perceived as the most pleasant. Hot water that makes you feel refreshed is ideal. However, caution is necessary as fatal bathing accidents often occur in baths with temperatures above 42°C.

The benefits of hydrostatic pressure

The hydrostatic pressure exerted on the body's surface when immersed in water puts the entire body under pressure, stimulating internal organs and making them move, similar to a natural massage. About one-third of the total blood circulation gathers in the legs, and this blood circulation may struggle to return to the heart due to gravity.

However, when immersed in water, hydrostatic pressure narrows the blood vessels and pushes the blood toward the heart (pump effect). As a result, blood circulation and lymphatic circulation are activated, improving the venous flow of the lower limbs and reducing the load on the heart. It is calculated that when one is immersed up to the shoulders, hydrostatic pressure equivalent to more than 500 kg is exerted on the total body surface. This hydrostatic pressure effect helps push blood and lymph fluids, providing a detoxifying effect.

The thermal effect and hydrostatic pressure effect stimulate the cardiac natriuretic hormone (atrial natriuretic peptide), increasing diuresis and facilitating the elimination of bodily waste, which also helps prevent pain.

 

Shima Onsen: A Timeless Hot Spring Retreat for Healing and Relaxation

Nestled in the tranquil mountains of Gunma Prefecture, Shima Onsen is a historic hot spring town that has provided comfort and healing for centuries. Renowned as one of the top three onsens in the Gunma region, along with Kusatsu and Ikaho, Shima Onsen has a rich history dating back to the Kamakura period. Surrounded by breathtaking nature in the Joshinetsu-kogen National Park, this serene onsen offers visitors not just relaxation, but also a sense of renewal.

The Healing Waters of Shima Onsen

 

A Hot Spring Legacy Since 989

Shima Onsen holds a special place in Japanese history as one of the oldest and most revered hot springs in the country. Legend has it that its waters have the power to heal 40,000 illnesses, giving the onsen its name ("Shima" meaning 40,000). The onsen was the first in Japan to receive national recognition as a hot spring health resort and boasts 42 abundant wellsprings. This generous supply of mineral-rich water has attracted visitors for generations, offering comfort and healing to all who come.

Types of Healing Springs

Shima Onsen is known for its various types of healing springs, particularly its Chloride and Sulfate springs, which have unique properties and benefits:

Chloride Springs: The Heat-Retaining Bath

Chloride springs, also known as "netsu no yu" or heat-retaining springs, are perfect for those who need extra warmth. The salt content in these springs prevents sweat from evaporating, helping the body retain heat and providing relief for conditions such as muscle and joint pain, sensitivity to cold, and chronic women’s diseases. After bathing, a layer of salt remains on the skin, enhancing the body's heat retention and giving the skin a smooth, moisturized finish.

Sulfate Springs: Nature's Healing Waters

Sulfate springs are divided into Calcium, Sodium, and Magnesium Sulfate springs, each with its own therapeutic effects. Calcium sulfate springs are particularly effective for high blood pressure, arteriosclerosis, and conditions like rheumatism and eczema. These springs, known as "Healing Springs," are ideal for post-stroke recovery and skin conditions, while drinking the water can aid with chronic pain and neuralgia.
