Note: The heat index, also known as 'real feel' or 'felt air temperature', is an aggregate value of air's warmth and moisture to show the human-felt temperature. An individual's perception of weather can be swayed by a variety of elements including metabolic differences, pregnancy status, and their level of physical exertion. Bear in mind that direct sunshine exposure increases weather impact, and may raise heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly important for children. Typically, children face more danger than adults as they usually perspire less. Their larger skin surface relative to their small bodies and increased heat output from their activities enhance their risk.
Perspiring is the body's way of cooling down, particularly by allowing sweat to evaporate and take the heat with it. In situations of high air temperature combined with high humidity (significant heat index), the body's ability to perspire is reduced, heightening the sense of warmth. Temperature imbalances caused by excessive heat retention can trigger heat-related maladies.

Protect your eyes, ears, face, and neck from the Sun by wearing a wide-brimmed hat.
