The influence of weather can be personal, changing with an individual's body mass, height, and level 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 quite important for children. Kids are generally in more danger than adults because they perspire less. Their large skin surface area compared to their small bodies and the excessive heat due to their actions raises their risk.
The body's natural response to excessive warmth is perspiration, as it allows for cooling through sweat evaporation. When there is an excess of moisture in the atmosphere, the efficiency of the evaporation process is lessened, leading to less efficient body cooling and a sensation of overheating. Accumulating heat beyond the body's cooling measures leads to rising temperatures and potential ailments.
