Heat index

When referencing the heat index, its values are suitable for shady environments and light breezes. When under direct sunshine, the heat index may be elevated by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', is the result of factoring in humidity to the air temperature, indicating perceived warmth. This impact is subjective, influenced by the person's physical activity and individual heat perception, affected by factors including wind, attire, and metabolic differences. Direct exposure to the sun's rays can enhance the felt temperature, increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for children. Young individuals usually face greater risks than adults as their sweat production is less. Also, their larger skin surface relative to their small bodies and the high heat generation due to their activity contributes to their vulnerability.
To achieve cooling, the human body employs perspiration, relying on the subsequent evaporation of sweat. Elevated relative humidity diminishes evaporation, thereby reducing the body's ability to shed heat and creating a feeling of being too warm. When body temperature rises due to excess heat gain beyond its removal capability, one might experience heat-related disorders.

Shield yourself from the harmful effects of UV radiation with sun-protective attire, a hat, and quality sunglasses.
