The impact of weather is individual, with diverse individuals experiencing it differently due to variations in body mass, height, and activity levels. With direct sunlight, be aware that it might enhance the heat sensation, raising the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are essentially critical for children. Children frequently do not comprehend the need for rest and hydration. Thirst is an advanced stage of dehydration - staying hydrated, especially during extended physical exercises, is essential.
As a reaction to high temperatures, the human body begins to perspire, using the evaporation of sweat to lower its temperature. When the air contains significant moisture, the efficiency of the evaporation process decreases, preventing the body from cooling down effectively and creating a feeling of overheating. When heat surpasses the body's release mechanisms, dehydration and overheating risks become pronounced.
