Note: The heat index, also known as 'real feel' or 'felt air temperature', reflects the feeling of heat when considering both air temperature and humidity. The impact of temperature is individual, as people's perception of weather may change based on their body mass, height, and physical activity. Given the impact of direct sunlight, it's noteworthy that the felt temperature can rise by 15 Fahrenheit (8 Celsius) degrees. Heat index values are largely significant for babies and toddlers. Youngsters are usually more at risk than adults, considering they sweat less. Additionally, their high skin surface area compared to their little bodies and their high heat production due to activity increases their risk.
Through perspiration, the body has a natural mechanism to eliminate excessive heat via sweat evaporation. With a high level of moisture in the air, the evaporation process becomes less efficient, preventing the body from cooling down efficiently and resulting in a sensation of overheating. Overheating and dehydration threats arise when heat gain goes beyond what the body can comfortably shed.

Undertake all key precautions, as unprotected skin and eyes may get burns in no time. The Sun's UV radiation is most potent between the hours of 10 a.m. and 4 p.m. Try to avoid direct sunlight during this time. On bright days sunglasses that block both UVA and UVB rays should be worn. A hat with a wide brim is extremely helpful, as it can prevent roughly 50% of UV radiation from reaching the eyes. Sunscreen with a sun protection factor of no less than 30 should be used liberally and reapplied frequently on overcast days, including after every swim or outdoor activity. Heads up! Sand and water reflection magnifies the UV exposure from the Sun.
