Note: The heat index, also known as 'feels like' or 'apparent temperature', is the result of factoring in humidity to the air temperature, indicating perceived warmth. The individual's experience of temperature can be shaped by numerous aspects such as metabolic variations, physical exertion, and attire. Direct sun rays have a notable impact on perceived temperature, which can raise the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are largely significant 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.
The physiological response of the human body to excess warmth is to perspire, thereby cooling itself through sweat evaporation. When the air contains significant moisture, the efficiency of the evaporation process decreases, preventing the body from cooling down effectively and creating a feeling of overheating. Elevated heat gain compared to the body's release capability poses risks of dehydration and potential overheating.

By wearing a generously brimmed hat, you can cut UV radiation exposure significantly.
