July's average heat index is evaluated at a blazing hot 116.6°F (47°C). Precaution: Heat cramps along with heat exhaustion are possible. Heatstroke is a serious risk with continued exertion.
It is important to note that the heat index values are for shaded areas and light wind scenarios. Heat index values may surge by up to 15 Fahrenheit (8 Celsius) degrees in the presence of direct sunlight.
Note: The heat index, also known as 'feels like' or 'real feel', is a measure of how hot it feels when the actual air humidity is factored in. Factors including metabolic differences, physical activity, and clothing are additional elements that influence the individual's temperature experience. One's exposure to direct sunlight has the potential to intensify the heat sensation, increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values remain especially vital for babies and toddlers. Youngsters generally face more threats than adults given their lesser ability to sweat. Coupled with their larger skin surface relative to their small bodies and higher heat production due to their activities, they are more endangered.
In response to overheating, the human body perspires to cool down, mainly through the evaporation of sweat. Under high air temperature and humidity (high heat index) conditions, perspiration is limited, and the perception of heat is increased. Accumulating heat beyond the body's cooling measures leads to rising temperatures and potential ailments.
