Heat index

In August, the average heat index is calculated to be a blistering 40°C (104°F). Greater preventive actions are needed, heat exhaustion and heat cramps are likely. Persistent activity could provoke heatstroke.
It is emphasized that the heat index's values are meant for shaded zones with mild winds. Direct sunshine exposure could raise heat index values by as much as 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', is calculated by taking the relative humidity value for a specific location and factoring it into the air temperature reading. The individual's impression of temperature can be affected by numerous factors such as metabolic variations, physical exertion, and attire. The sun, when shining directly, can have a significant impact on the perceived temperature, increasing the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly important for children. Young ones often underestimate the need for rest and rehydration. Thirst appears late in dehydration - hence, it is important to keep hydrated, particularly during prolonged physical activities.
The human body normally cools itself by perspiration. Excessive warmth is eliminated from the body by evaporation of sweat. An elevated level of relative humidity hinders evaporation, leading to decreased heat elimination from the body, inducing a sensation of excess heat. When body temperature rises due to an imbalance in heat gain, there's a potential for dehydration and overheating.

Beware of overexposure. Fair-skinned individuals risk burning in less than 20 minutes. Remember that UV radiation from the Sun is strongest between 10 a.m. and 4 p.m. Make an effort to limit direct sun exposure during this time. Sun protection is enhanced with clothing that boasts a tight weave yet offers a loose fit.
