Heat index

During September, the heat index is evaluated at a blistering 40°C (104°F). Adopt special protective actions against heat exhaustion and heat cramps. Long-duration activity risks heatstroke.
Records show heat index calculations are tailored for shaded regions and mild winds. Exposure to direct sunlight may make the heat index values climb by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'apparent temperature', is a value derived by merging air temperature with the humidity to convey how the climate feels. The influence of weather can be personal, changing with an individual's body mass, height, and level of physical exertion. It is essential to realize that direct sunlight can escalate the perceived temperature, increasing the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant 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.
The human body cools itself through perspiration, as excessive warmth is removed from the body through sweat evaporation. With high air temperature and humidity (high heat index) conditions, sweat production is restricted, leading to an amplified perception of heat. When body temperature rises due to excess heat gain beyond its removal capability, one might experience heat-related disorders.

Stand by precautions and apply sun safety measures. Evading sunburn is of great 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. Opt for tightly woven and loose clothing to enhance protection from the Sun. Beware! Reflecting off water and sand, UV rays are much stronger.
