The influence of weather is personal, differing among individuals based on variations in body mass, stature, and the degree of physical exertion. You should know that direct sun exposure can heighten weather effects, potentially elevating the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are primarily vital for children. Young ones often do not realize the necessity to rest and replenish their fluids. Thirst is a delayed indication of dehydration - keeping hydrated, particularly in prolonged physical activity, is crucial.
The human body cools itself through perspiration, as excessive warmth is removed from the body through sweat evaporation. An increase in relative humidity disrupts body cooling by slowing the evaporation rate, thereby reducing the rate at which the body cools and amplifying the sense of heat. Heat-related complications, like dehydration, can manifest if the body's heat gain exceeds its dissipation capacity.
