Note: The heat index, also known as 'felt air temperature' or 'feels like', is an index that combines air temperature and relative humidity to determine the human-perceived temperature equivalent. A person's impression of weather can be affected by numerous aspects, among them metabolic variations, pregnancy, and activity levels. One must note that being under the direct sun can escalate the heat's effects, with the heat index possibly rising by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical for babies and toddlers. Young individuals usually face greater risks than adults as their sweat production is less. Also, their larger skin surface relative to their small bodies and the high heat generation due to their activity contributes to their vulnerability.
One way the human body deals with excessive warmth is by perspiring and allowing sweat to evaporate. An increase in relative humidity hinders the body's normal cooling function by reducing evaporation, thereby decreasing the rate of body cooling and enhancing the sense of warmth. When body temperature rises due to excess heat gain beyond its removal capability, one might experience heat-related disorders.

Eschew overexposure. Those with light skin may suffer burns in fewer than 20 minutes. Avoid direct Sun exposure and seek shade from 10 a.m. to 4 p.m., the period of highest UV radiation. Remember, however, that not all shade structures offer full protection. Select sunglasses that boast both UVA and UVB protection to limit the adverse effects of the sun on the eyes.
