Heat index

It is important to note that the heat index values are for shaded areas and light wind scenarios. Exposure to the direct sun might augment heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'apparent temperature', provides an understanding of perceived warmth by combining temperature and relative humidity. The individual's temperature perception can be influenced by numerous factors such as metabolic variations, physical activity, and clothing. It is noteworthy that being in direct sunlight can enhance the weather's impact, raising the heat index by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are essentially critical for children. 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.
One of the main methods the human body employs to cool down is by perspiring, as this process allows sweat to evaporate and remove excess heat. Higher relative humidity impedes evaporation, thus reducing heat dispersion from the body, culminating in a sensation of overheating. Overheating and dehydration threats arise when heat gain goes beyond what the body can comfortably shed.

Escape overexposure. People with light skin may incur burns in fewer than 20 minutes. Avoid direct exposure to the Sun between 10 a.m. and 4 p.m., the peak period for UV radiation, noting that objects like parasols or canopies might not offer complete sun protection. During bright days, sunglasses that offer UVA and UVB defense are recommended.
