Key Points of the Bicarbonate Bath Method Bicarbonate Ions

When you enter a carbonated bath, your body gets covered with tiny bubbles of carbon dioxide gas.
While these bubbles have been thought to produce various effects, the key component is actually the bicarbonate ion.

Neutral pH

Natural carbonated springs, such as those in German therapeutic baths and Nagayu Onsen, have a neutral pH of 6.7 to 7.1. In a neutral pH environment, acidic carbon dioxide gas cannot exist,
so most of it converts into bicarbonate ions.

Lukewarm Bathing

For a lukewarm bath, dissolve three tablets in 160 liters of water (or four tablets in 200 liters).
Use water temperatures between 96.8°F and 105.8°F (36°C to 41°C). In summer, a relaxing bath at 96.8°F (36°C) is ideal, while in winter, a soak below 105.8°F (41°C) for more than 15 minutes is recommended.

 

Refreshing Bicarbonate Shower

Bicarbonate Shower Cleansing Method for Dry Hair and Skin.
For those with dry hair and skin, we recommend the “Bicarbonate Shower Cleansing Method.” Using chemical-laden shampoos and body soaps on already dry and damaged hair and skin can exacerbate the damage. However, not using cleansing products can leave residues and dirt behind.

To gently cleanse your hair and skin, use the bicarbonate shower.

Place one HOT TAB tablet in a special showerhead. As the water flows through, it will dissolve the bicarbonate, transforming the shower water into a bicarbonate-rich solution.

This method cleanses your skin and scalp without damaging the skin barrier, providing moisture and promoting healthy skin.
