Note: The heat index, also known as 'feels like' or 'real feel', is a calculation that merges air temperature and relative humidity to depict the sensation of warmth. The effect of weather is individual, with a variety of people experiencing it differently due to distinctions in body mass, height, and level of activity. It is essential to realize that direct sunlight can escalate the perceived temperature, increasing the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to children. Young ones are generally more prone to risk than adults due to their reduced ability to sweat. Their large skin surface area relative to their diminutive bodies and elevated heat production from their activities further enhance this risk.
Perspiring is the body's way of cooling down, particularly by allowing sweat to evaporate and take the heat with it. When relative humidity is heightened, it slows the rate of evaporation, thereby decreasing the body's ability to shed heat and creating a sensation of overheating. Inadequate heat shedding in the face of rising body temperatures hints at potential dehydration risks.
