The effect of weather is individual, with a variety of people experiencing it differently due to distinctions in body mass, height, and level of activity. Realize that direct exposure to sunlight can augment the felt heat, leading to a potential increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to children. Young ones regularly neglect the requirement for rest and fluid replenishment. Thirst is a late stage of dehydration - so, it is necessary to keep hydrated, particularly during extended periods of physical exertion.
As a reaction to high temperatures, the human body begins to perspire, using the evaporation of sweat to lower its temperature. When relative humidity increases, the body's capacity to evaporate heat decreases, leading to a heightened sense of warmth. Elevated heat gain compared to the body's release capability poses risks of dehydration and potential overheating.
