It is important to note that the heat index values are for shaded areas and light wind scenarios. If directly exposed to the sun, the heat index could rise by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'feels like', is the result of factoring in humidity to the air temperature, indicating perceived warmth. The influence of weather can be personal, changing with an individual's body mass, height, and level of physical exertion. With direct sunlight, be aware that it might enhance the heat sensation, raising the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular significance for children. Children often overlook the need for breaks and fluid intake. Thirst is a late-stage sign of dehydration - hence, it is necessary to stay hydrated, especially during extended periods of physical activities.
Perspiring is a crucial mechanism for the human body, allowing it to release excessive warmth through evaporating sweat. Under high air temperature and humidity (high heat index) conditions, perspiration is limited, and the perception of heat is increased. If heat absorption isn't effectively countered by the body's cooling methods, body temperature surges, hinting at potential problems.

Evade overexposure. Individuals with fair skin risk burning in under 20 minutes. Avoid direct Sun exposure and seek shade from 10 a.m. to 4 p.m., the period of highest UV radiation. Remember, however, that not all shade structures offer full protection. A hat with a generous brim can prevent nearly 50% of UV rays from reaching your eyes.
