Note: The heat index, also known as 'felt air temperature' or 'real feel', melds the effects of warmth and moisture to generate a feeling of heat. Elements such as metabolic variations, being pregnant, and physical activity can impact one's weather perception. Sunshine, when direct, has the potential to intensify weather effects, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical to babies and toddlers. Young individuals usually face more risks than adults due to their lower sweat production. Their large skin surface area relative to their tiny bodies and high heat production from their activities adds to their risk.
To cool down, the human body relies on perspiration, a process where excessive heat is eliminated as sweat evaporates. With higher relative humidity, the rate of evaporation is reduced, resulting in increased heat retention in the body compared to drier air. When the heat gained surpasses the body's cooling capacity, temperatures rise, signaling potential health concerns.
