Note: The heat index, also known as 'apparent temperature' or 'real feel', gauges the sensation of temperature factoring in the air's moisture content. The impression of weather on a person can be swayed by additional aspects, including metabolic variations, pregnancy, and activity levels. Direct sun rays can make one feel hotter, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for babies and toddlers. Young individuals usually face more risks than adults due to their lower sweat production. Their large skin surface area relative to their tiny bodies and high heat production from their activities adds to their risk.
The innate cooling system of the human body revolves around perspiration, with the evaporation of sweat being central to this process. Under conditions of increased relative humidity, the evaporation rate lessens, causing the body to retain more heat than under less humid conditions. Should the body fail to balance its heat gain, the escalating temperature poses health challenges.

Stick with precautions and abide by sun safety procedures. Evading sunburn is essential. Stay in the shade and limit sun exposure from 10 a.m. to 4 p.m., when UV radiation is most potent. Keep in mind that shade structures like parasols or canopies do not offer full protection. On sunny days, it's ideal to wear sunglasses that filter out UVA and UVB rays.
