Thirst usually appears late during dehydration - therefore, maintaining hydration, particularly during long physical activities, is essential.
To achieve cooling, the human body employs perspiration, relying on the subsequent evaporation of sweat. In the presence of high relative humidity, the evaporation rate diminishes, resulting in the body retaining more warmth compared to dry conditions. When the body's heat gain surpasses its removal capacity, body temperature starts to climb, leading to potential heat-related ailments.
