Note: The heat index, also known as 'feels like' or 'real feel', is an index that combines air temperature and relative humidity to determine the human-perceived temperature equivalent. Additional elements including metabolic differences, the level of physical activity, and attire have a role in shaping the individual's temperature perception. The sun, when shining directly, can have a significant impact on the perceived temperature, increasing the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values remain especially vital for babies and toddlers. Younglings are generally more in peril than adults due to their reduced perspiration. Coupled with a larger skin surface relative to their tiny bodies and greater heat production because of their activity, they become more at risk.
Perspiring is the body's way of cooling down, particularly by allowing sweat to evaporate and take the heat with it. When the relative humidity is high, the evaporation rate is reduced. The warmth is removed from the body at a lower rate, causing the body to retain more heat than it would in dry air. Heat disorders may be on the horizon when body temperatures rise from inadequate heat management.
