Heat index

August's heat index is appraised at a torrid 36°C (96.8°F). More protective measures are required - heat exhaustion and heat cramps are likely. Heatstroke may follow lengthy activity.
Take into consideration that the heat index values are calculated for shade and light wind conditions. Facing direct sunlight may hike up the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'apparent temperature', is a calculation that merges air temperature and relative humidity to depict the sensation of warmth. The individual's experience of temperature can be shaped by numerous aspects such as metabolic variations, physical exertion, and attire. It is noteworthy that being in direct sunlight can enhance the weather's impact, raising the heat index by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are largely significant for babies and toddlers. Juveniles often do not understand the need to recuperate and rehydrate. Thirst is a delayed symptom of dehydration - hence, it is vital to maintain hydration, particularly during ongoing physical activities.
To prevent overheating and help regulate its internal temperature, the human body sweat and rely on the evaporation to cool down. When relative humidity is heightened, it slows the rate of evaporation, thereby decreasing the body's ability to shed heat and creating a sensation of overheating. When heat uptake goes beyond the body's cooling mechanisms, there's a surge in body temperature, posing health risks.
