Heat index

During May, the heat index is appraised at a fiery hot 39°C (102.2°F). More safety actions are required, heat exhaustion and heat cramps are probable. Long-term activity may precipitate heatstroke.
Heat index readings emphasize conditions of light breezes and shaded spots. Exposing to direct sunshine may enhance heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', integrates the air's temperature and its humidity to showcase the felt temperature by people. Additional factors encompassing metabolic differences, the level of physical activity, and clothing can impact the individual's perception of temperature. Understand that direct sun rays can influence the weather's impact, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are primarily vital for children. In general, younger individuals are at greater risk than adults because they tend to sweat less. Also, having a larger skin surface to body size ratio and greater heat production due to their active behavior contribute to this danger.
Perspiring is a crucial mechanism for the human body, allowing it to release excessive warmth through evaporating sweat. In high relative humidity, the body's ability to evaporate heat is diminished, resulting in a heightened feeling of warmth. Rising body temperatures resulting from an imbalance in heat absorption can lead to potential thermal issues.

Using UVA and UVB-protective sunglasses and sun-protective clothing is effective against UV radiation.
