④Sulfate Springs

硫酸塩泉

"Hot spring for strokes", "Hot spring for cuts", "Hot spring for skin revitalization and beauty"

Hot springs with more than 1,000 mg of dissolved substances (excluding gaseous substances) in 1 kg of hot spring water, and with Sulfate Ions(SO42-as the main anion.
Indications for bathing according to spring quality are Cuts, Peripheral circulatory disturbance, Sensitivity to cold, Depression, and Dry skin, which are the same as for the Chloride Springs. Indications for drinking according to spring quality are Biliary system disease, Hypercholesterolemia, and Constipation, as it promotes the secretion of bile. Note that only Sulfate Springs and Chloride Springs have Constipation as an Indication for drinking. This spring quality stimulates skin revitalization (activates metabolism). Specifically, Cuts, Burns, Acne, Psoriasis, Itching, Chronic Eczema, etc. are treated with this spring water. Thus, Sulfate Springs, like Chloride Springs, are also called “Hot springs for cuts”.
The “Sulfate Springs” is also highly effective for oily skin because of its ability to wash away excess oil on the skin. The sulfate ions also have the effect of sending more oxygen into the blood, rehydrating skin, stimulating collagen production, making the skin taut and moisturized, which is an anti-aging effect. This is why it is called “Hot springs for rejuvenation” and “Hot springs for beautiful skin”. “Sulfate springs” are classified according to the main component of cations as follows.

(1)Sodium-Sulfate Springs
Sodium Ion's heat-retaining and sterilizing effects warm the body, relieve pain, and sterilize the body. Also, Sulfate Ions have a reviving (anti-aging) effect that stimulates the production of collagen. The combination of these two cations and anions is called "Hot spring for cuts".

(2)Calcium-Sulfate Springs
The calming effect of Calcium Ion relieves pain and inflammation, and is said to be effective in treating hypertension, arteriosclerosis, and other vascular conditions. Because of its effectiveness in preventing vascular problems, it is also called "Hot spring for strokes". Also, Calcium Ions promote the formation and regeneration of the stratum corneum, and Sulfate Ions enhance the skin's elasticity function and prevent the formation of wrinkles. The combination of these two cations and anions is called "Hot spring for beauty".

(3)Magnesium-Sulfate Springs
Magnesium Ions have a calming effect that strengthens the skin barrier function, lowers blood pressure, and relieves pain. Sulfate Ions dilate blood vessels and stimulate blood circulation. The combination of these two cations and anions is called "Hot spring for strokes".
