Note: The heat index, also known as 'felt air temperature' or 'feels like', melds the effects of warmth and moisture to generate a feeling of heat. The influence of weather can be personal, changing with an individual's body mass, height, and level of physical exertion. Bear in mind that direct sunshine exposure increases weather impact, and may raise heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for babies and toddlers. In general, children are more at risk than adults because they sweat less. Furthermore, the large skin surface compared to their small bodies and the high heat production due to their actions contribute to this vulnerability.
Normally, the human body cools itself through perspiration, which removes excessive heat by evaporating sweat. Elevated relative humidity disrupts typical body cooling by reducing the evaporation rate, consequently decreasing the body's cooling rate and enhancing the feeling of heat. Overheating can ensue when the body accumulates more heat than it can release, and dehydration severity may vary.

Make an effort to avoid direct sun exposure between 10 a.m. and 4 p.m., the peak period for UV radiation, and note that objects like parasols or canopies might not offer full sun protection. Limit sun-induced ocular harm with sunglasses that feature UVA and UVB filtration. Apply generously and frequently reapply a sunscreen with SPF 30 or more even on cloudy days, particularly after a swim or outdoor exercise.
