Note: The heat index, also known as 'feels like' or 'apparent temperature', melds the effects of warmth and moisture to generate a feeling of heat. The effect of weather is individual, with a variety of people experiencing it differently due to distinctions in body mass, height, and level of activity. Awareness is key; direct sunlight can enhance the weather's impact, possibly boosting the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for children. Kids generally face higher risks than adults as they sweat less. Along with their large skin surface compared to their small bodies and higher heat production due to their activities, their vulnerability is increased.
The physiological response of the human body to excess warmth is to perspire, thereby cooling itself through sweat evaporation. 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 the body accumulates more heat than it can release, body temperature goes up, increasing the risk of heat-related health issues.

Limit direct exposure to the Sun during these hours. On sunny days, it's ideal to wear sunglasses that filter out UVA and UVB rays.
