Type and the Benefit of ONSEN

            Medically speaking, there are 9 types of ONSEN, which are regarded as having healing effects. In such estavlishments, these calims are usually clearly displayed. Bathing in the right ONSEN can be an effective cure for some illnesses.

            In Japan, it is said ONSEN have various medical effects. Japanese people believe that a good soak in proper ONSEN heals aches, pains and diseases, and visit ONSEN to treat the illnesses, such as arthralgia, chronic skin,

            ONSEN are commonly effective as a result of mineral activity and temperature. Depending on the quality of the spa, the unique characteristics can vary. The quality and type of ONSEN is determined according to a number of groups such as the mineral content found in the spring water, and the quantity.


The following chart shows type of ONSENS and its benefit.
 
ONSEN TYPE CHARACTERISTIC AND QUALIFICATION
Simple ONSEN
 
Even if the hot spring has a temperature of 25degrees,
The overall mineral composition within 1 kg water adds up to less than 1000mg. The level of stimulation is low. But there will potentially be a wide range of effects when used.
 
Carbon Dioxide ONSEN
 
A’Carbon Dioxide ONSEN’is where in 1 kg of hot spring water. There is 100mg or more of released carbonic acid. This causes carbon dioxide to dissolve, creating a fine froth on the surface, and it is often referred to as a ‘bubbly spa’ or ‘soda spa’ The ONSEN has the effect of expanding blood vessels, helping to lower blood pressure.
 

Sodium Bicarbonate Saline

ONSEN

 
 
This type of ONSEN is alkaline, and there are two different types: Sodium Bicarbonate and Bicarbonate Earth ONSEN.it is a clear colour and has the ability to make skin feel smooth, and in particular sodium bicarbonate makes skin soft and gentle, while removing dirt, often being called ‘the water of beautiful skin’.
 

 
Chloride ONSEN

 
 

 
Containing salt similar to the kinds found in sea water, the salt has the effect of controlling perspiration after bathing, also means that the body’s ability to retain heat is also excellent. This type of ONSEN is known as’ Fever water’


Sulphate ONSEN

The spring water, with a bitter taste when drunk, has been known as ‘Water for cuts and bruises’. Sulphate onsen are divided into three categories: Calcium sulphate, Sodium sulphate, containing traces of natrium, and a regular bitter spring which contains traces of magnesium.
 
 Ferruginous ONSEN (lron) There are two types of Ferruginous ONSEN: Carbonated lron ONSEN, and Melanterite ONSEN. The water is a colourless, transparent as it gushes up, but as it comes into
 
 
 
Contact with the atmosphere, it develops into a dark reddish-brown colour and weakens the waters effect. This type of spring helps the body’s iron levels.

 Aluminium ONSEN

Colourless and transparent, or a yellowish-brown colour with a bitter taste, these acidic springs have strong sterilizing properties.
 

 Cupriferous/Ferruginous

ONSEN (Copper and lron)

Similar to the Ferruginous spring, the water oxides with the atmosphere once exposed, becoming an opaque yellow colour, and leaving a red-brown sediment is known as ‘Hot water flowers’. The sulphur can soften the hardened keratin of the skin, and is also good for acne and spots.
 
Sulphur Onsen With the distinctive and unique smell of bad eggs, this kind of spring has the ability to expand the blood vessels in the body. Because the hydrogen sulphide in the spring is toxic, proper ventilation is essential. The pale-yellow sediment is known as ‘Hot water flower’s. The sulphur can soften the hardened keratin of the skin, and is also good for acne and spots.

Acidic ONSEN

This type of spring has powerful sterilizing properties, and a strong stimulation that permeates the skin. Acidic ONSEN are not recommended for people with sensitive skin or weak health.
Radioactive ONSEN Only tiny amounts of radioactive minerals are found in this type of hot spring, and it can also be referred to as a ‘Radium ONSEN’ or ‘Radon ONSEN’. Strong evidence has been recorded that shows the miniscule amounts of radioactivity in the water have a beneficial effect on the body.
