Factors such as metabolic variation, pregnancy, and physical activity play a role in one's impression of weather. Awareness is key; direct sunlight can enhance the weather's impact, possibly boosting the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical to babies and toddlers. Kids are usually more vulnerable than adults, given their lesser sweating ability. Along with their larger skin surface relative to their small stature and the excess heat due to their activity, their risk is amplified.
To cool down, the human body relies on perspiration, a process where excessive heat is eliminated as sweat evaporates. In the presence of elevated relative humidity, the evaporation rate decreases. This reduction leads to increased body heat retention compared to conditions of dry air. Accumulating heat beyond the body's cooling measures leads to rising temperatures and potential ailments.
