Note: The heat index, also known as 'apparent temperature' or 'feels like', is a numerical representation of warmth when taking temperature and moisture levels into account. 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. 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 especially crucial for babies and toddlers. Children often lack awareness of the importance of taking breaks and rehydrating. The feeling of thirst is a late indication of dehydration, so maintaining hydration, especially during long periods of physical activity, is critical.
When the body gets too warm, it perspires, leading to sweat evaporation which cools it down. When the relative humidity is high, the evaporation rate is reduced. The warmth is removed from the body at a lower rate, causing the body to retain more heat than it would in dry air. As body temperatures escalate without effective heat release, one might face dehydration threats.

Avoid excessive sunlight. Those with lighter skin may experience burning in less than 20 minutes. Seek shade and minimize exposure to direct Sun in a period between 10 a.m. and 4 p.m. when UV radiation is most intense; keep in mind that shade structures like parasols or canopies do not provide perfect sun protection. Limit sun-induced ocular harm with sunglasses that feature UVA and UVB filtration.
