The impression of weather on a person can be swayed by additional aspects, including metabolic variations, pregnancy, and activity levels. Direct exposure to the sun's rays can enhance the felt temperature, increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for babies and toddlers. Typically, children face more danger than adults as they usually perspire less. Their larger skin surface relative to their small bodies and increased heat output from their activities enhance their risk.
Evaporating sweat, thanks to perspiration, acts as a natural air conditioner for the human body. With excessive moisture in the atmosphere, the effectiveness of the evaporation process is decreased, causing the body to cool down less efficiently, leading to a sensation of overheating. Heat-related challenges, like dehydration, can be anticipated when body heat isn't managed effectively.
