Note that heat index values are valued for light wind and location in the shade. Exposing to direct sunshine may enhance heat index values by 15 Fahrenheit (8 Celsius) degrees.Note
: The heat index, also known as 'real feel' or 'feels like', reflects the feeling of heat when considering both air temperature and humidity. This effect is subjective, differing among individuals based on their physical activity and perception of heat, which can be influenced by factors like wind, clothing, and metabolic variances. Understand that direct sun rays can influence the weather's impact, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are largely 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 human body cools itself through perspiration, as excessive warmth is removed from the body through sweat evaporation. With an abundance of moisture present in the air, the process of evaporation becomes less effective, and the body fails to cool down as it should, leading to the sensation of overheating. When heat gain surpasses the level the body can shed, body temperature begins to increase, and consequently, overheating and dehydration can occur, with varying severity.

Adopt all essential precautions. Preventing sun harm is crucial. UV radiation from the sun is at its strongest between 10 a.m. and 4 p.m. Try to limit direct exposure during these hours. To cut down UV radiation exposure by about half, sport a wide-brim hat. Prompt application of a broad-spectrum sunscreen, SPF 30+, is necessary after a swim or an outdoor workout and it should be re-applied every two hours.
