Heat index

May's average heat index is calculated to be a very hot 39°C (102.2°F). Greater safety measures are needed, risk of heat exhaustion and heat cramps is high. Continuous activity might trigger heatstroke.
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 'felt air temperature' or 'feels like', comes about by integrating the temperature readings with the humidity levels. The individual's impression of temperature can be affected by numerous factors such as metabolic variations, physical exertion, and attire. Direct exposure to sun rays can potentially augment the heat sensation, elevating the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular importance for children. Juveniles are regularly less conscious of the need to recuperate and rehydrate. Thirst is a tardy symptom of dehydration - hydration, especially during lengthy physical activities, should be maintained.
The innate cooling system of the human body revolves around perspiration, with the evaporation of sweat being central to this process. In circumstances of high air temperature and humidity (high heat index), the body's perspiration is restricted, heightening the feeling of warmth. As the body accumulates more heat than it can release, body temperature goes up, increasing the risk of heat-related health issues.

Inhibit overexposure. Warding off sun damage is of utmost importance. Seek shade and minimize exposure to direct Sun in a period between 10 a.m. and 4 p.m. when UV radiation is most intense; keep in mind that shade structures like parasols or canopies do not provide perfect sun protection. Sun-related eye harm can be minimized with proper sunglasses offering UVA and UVB coverage.
