Heat index

The heat index in August is evaluated at a torrid 98.6°F (37°C). Incorporate extra safety measures to avoid heat exhaustion and heat cramps. Continuous activity could provoke heatstroke.
For clarity, heat index numbers account for light winds and areas under shade. Direct sunlight can potentially boost the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'feels like', embodies the combination of air temperature and moisture content to illustrate perceived heat. Elements such as metabolic variations, pregnancy, and physical exertion can shape one's weather perception. In the direct sunlight, the weather's impact can be amplified, possibly boosting the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to children. Children regularly disregard the necessity to rest and replenish fluids. Thirst is a late symptom of dehydration - thus, maintaining hydration, particularly during long-lasting physical activities, is essential.
To prevent overheating and help regulate its internal temperature, the human body sweat and rely on the evaporation to cool down. With an abundance of moisture present in the air, the process of evaporation becomes less effective, and the body fails to cool down as it should, leading to the sensation of overheating. Exceeding the body's heat disposal threshold results in a rise in body temperature and potential thermal disorders.

Sustain precautions and conform to sun safety norms. Preventing sunburn is necessary. Avoid direct Sun exposure from 10 a.m. to 4 p.m., a period when UV radiation is most intense, and remember that not all shade structures provide full protection. To cut down UV radiation exposure by about half, sport a wide-brim hat. Caution! The Sun's UV rays become stronger due to reflections from water and sand.
