Heatstroke is a general term for disorders that develop when the balance of water and salt (sodium, etc.) in the body breaks down or the body's ability to adjust fails in a hot and humid environment. Symptoms such as fatigue, loss of consciousness, and fainting may appear.
To prevent heatstroke, it is recommended to properly manage your work environment, drink water, take salt, and wear clothes with good moisture permeability and breathability.

Shigematsu offers personal coolers that do not require a refrigerant (using dry compressed air that does not contain oil mist) as products for heat stroke prevention.
