We are aware of importance of precautions against heat stress disorders during summer. However, even before a rainy season has a danger of heat stress disorders. Temperature may not be as high as summer but humidity is high during and before a rainy season. It causes heat stress disorders because our bodies do not sweat to cool down since the temperature is not high enough, and the heat stays inside our bodies without being able to release the heat. This happens when humidity is high. Heat stress disorders are caused by body tempera rise, and dehydration which is unbalance of electrolyte (fluids and salinity balance).

Classification of heat stress disorders: heat syncope, heat exhaustion, heat cramp, and heat stroke

First aid of heat stress disorders

Our work requires long sleeves due to the safety purpose, and we often work outside, especially carpenters mainly work outside. Therefore, for an emergency, we keep a room air-conditioned with cool temperature, and provide oral rehydration solutions and ice-cream/ice-candies for anyone require to cool down. In a hot season, staffs wear an air-conditioning clothe with a fan installed inside. It is important to keep an eye on each other's conditions as we as eating healthy and sleep well day by day to keep your body and mind fit and healthy.
