Refresh your body and mind in a Japanese onsen

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.

My Journey to Hyakkannon: A transformative Onsen Experience

The Location of Hyakkannon Onsen

Nestled in Saitama, just 60 kilometers from Tokyo by car, Hyakkannon offers a serene escape from the bustling city life. The onsen is located at the entrance of a beautiful Buddhist temple dedicated to Kannon, the goddess of mercy. This tranquil setting provides a perfect blend of cultural and natural beauty, making it an ideal destination for relaxation and spiritual reflection.

Hyakkannon's Chloride Springs: A Salt-Infused Sanctuary for Body and Soul

Hyakkannon features a unique chloride spring, also known as a salt spring. This type of spring contains salt and shares properties similar to seawater. The salt on your skin after bathing prevents the evaporation of sweat, keeping you warm and comfortable long after your soak. The onsen's environment, with its spiritual and serene ambiance, enhances the overall experience, making it not just a physical retreat but also a mental and emotional one.

Health Benefits of Hyakkannon Onsen

The chloride spring at Hyakkannon is particularly beneficial for the elderly or those recovering from illness. The mineral-rich waters are effective for treating various conditions, including:

• Muscle and joint pain: The warm, mineral-laden water helps soothe sore muscles and joints.
• Contusions and sprains: The healing properties of the salt spring aid in the recovery from bruises and sprains.
• Sensitivity to cold: The warmth retained by the salt on the skin helps combat sensitivity to cold, providing lasting warmth.

The spring quality at Hyakkannon Onsen is exceptional, characterized by its weakly alkaline nature (pH 7.67) and high concentration of sodium ions (6412 mg) and calcium ions (439.3 mg). This unique composition results in significant skin benefits, earning it the nickname "beauty bath." Here's a detailed look at its properties:

• Spring Quality: Strong sodium chloride saline hot spring
• Discharge Type: Natural artesian spring
• Spring Temperature: 57 degrees Celsius
• pH: 7.90 (weakly alkaline)
• Total Mineral Content: 18,510 mg per liter

The interaction between the carboxylic acids in the skin's sebum and the sodium and calcium ions forms sodium carboxylate and calcium salts, leading to a high beautifying effect on the skin.

Benefits of Carbonated Springs

When you bathe in Hyakkannon’s high-concentration carbonated spring, bubbles form all over your body. This phenomenon occurs as carbon dioxide dissolves in the hot spring water, attaching to your skin and making it feel like you're enveloped in carbon dioxide. This gas permeates the skin, dilates blood vessels, improves blood circulation, and makes you feel warm.
