Heat index

May's mean heat index is appraised at a burning hot 45°C (113°F). Remain cautious: Heat cramps along with heat exhaustion are foreseeable. Ongoing activity may precipitate heatstroke.
The standards for the heat index are set for locations in shade and under light breezes. The heat index may scale up by 15 Fahrenheit (8 Celsius) degrees with direct sun exposure.
Note: The heat index, also known as 'real feel' or 'felt air temperature', comes about by integrating the temperature readings with the humidity levels. Additional elements including metabolic differences, the level of physical activity, and attire have a role in shaping the individual's temperature perception. Considering the impact of direct sunlight, it's possible for the heat index to surge by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly meaningful 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.
Perspiring is how the human body naturally cools down, as sweat's evaporation takes away excess heat. 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. With body temperatures on the rise, inefficient heat shedding can lead to dehydration and its associated complications.

Sidestep overexposure. Individuals with fair complexions risk burning in fewer than 20 minutes. Avoid direct Sun exposure from 10 a.m. to 4 p.m., a period when UV radiation is most intense, and remember that not all shade structures provide full protection. Boost your sun resistance with garments that are densely woven yet spacious.
