Heat index

For most parts of May, the heat index is evaluated at a fiery hot 39°C (102.2°F). Implement additional cautionary measures, heat cramps and heat exhaustion could occur. Prolonged activity might induce heatstroke.
It is worth noting that heat index values are gauged for conditions in the shade and light breezes. Direct sunlight has the potential to heighten heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', is achieved by amalgamating air temperature with the relative humidity readings. One's weather perception can be influenced by a range of factors including metabolic differences, being pregnant, and their level of physical activity. 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 especially crucial for babies and toddlers. Young people are generally more susceptible than adults because they perspire less. Furthermore, their proportionally larger skin surface to their petite bodies and the increased heat output from their actions add to the risk.
Evaporating sweat is a key way the human body dispels excessive warmth, all thanks to the process of perspiration. Excessive relative humidity disturbs the body's typical cooling process by reducing evaporation, leading to a decrease in body cooling rate and an increase in the sensation of warmth. As the body accumulates more heat than it can release, body temperature goes up, increasing the risk of heat-related health issues.

Shun overexposure. Protection from sun ravages is indispensable. The Sun's UV radiation is most potent between 10 a.m. and 4 p.m. Try to limit direct exposure to the Sun during this period. A hat with a broad brim is indispensable, filtering out up to half of UV rays. Caution! The mirror effect of sand and water ups the UV radiation strength.
