Heat index

The metrics for the heat index are tailored for both shady environments and light winds. When exposed to the direct sun, the heat index may augment by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', integrates the air's temperature and its humidity to showcase the felt temperature by people. An individual's temperature experience can be influenced by extra factors, including metabolic differences, activity levels, and clothing. Be mindful that being in direct sunlight might mean feeling hotter, with the heat index rising by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for babies and toddlers. Children often do not understand the need to rest and hydrate. Thirst is a late manifestation of dehydration - therefore, it is essential to stay hydrated, particularly during prolonged physical activities.
Perspiring is the body's way of cooling down, particularly by allowing sweat to evaporate and take the heat with it. When the air holds a significant amount of moisture, the efficiency of the evaporation process is decreased, preventing the body from cooling down efficiently, leading to the sensation of overheating. Rising body temperatures resulting from an imbalance in heat absorption can lead to potential thermal issues.

Avert overexposure. Light-skinned people might experience burning in less than 20 minutes. Avoid exposure to the Sun and try to stay in the shade between 10 a.m. and 4 p.m., when UV radiation is most potent, but be aware that parasols or canopies may not offer full protection. A wide-brimmed hat is a shield, deflecting up to 50% of harmful UV radiation from eyes.
