Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', stands as a testimony to how temperature and humidity combine to impact our sense of warmth. Additional factors encompassing metabolic differences, the level of physical activity, and clothing can impact the individual's perception of temperature. Given direct exposure to sunlight, one might experience a rise in the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values remain especially vital for babies and toddlers. Young individuals usually face greater risks than adults as their sweat production is less. Also, their larger skin surface relative to their small bodies and the high heat generation due to their activity contributes to their vulnerability.
When the body gets too warm, it perspires, leading to sweat evaporation which cools it down. 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. When heat gain exceeds the level the body can remove, body temperature begins to rise, and heat-related illnesses and disorders may develop.

Use measures and accept sun safety conventions. Guarding against skin and eye trauma is of high priority. Stay in the shade and limit direct Sun exposure from 10 a.m. to 4 p.m., a time when UV radiation is particularly strong. Remember, however, that shade structures may not provide complete protection. A wide-brimmed hat is a staple for defending the face, eyes, ears, and neck from the Sun.
