For those living in Ishigaki Island, the body is often under constant stress from daily habits—air conditioning, quick showers without soaking in a warm bath, and frequent consumption of cold drinks can lead to excessive internal coldness, placing a burden on the internal organs. As a result, many experience imbalances in the autonomic nervous system, hormone levels, and immune function. Additionally, the island’s strong UV rays can accelerate the production of reactive oxygen species in the body, which contributes to skin damage. We hope to become a source of relief and care for the people of this island—a place where your body and skin can recover, heal, and thrive.
