Heat index

For most parts of August, the heat index is calculated to be a torrid 96.8°F (36°C). Heightened safety actions are necessary, heat cramps and heat exhaustion are probable. Persistent activity may lead to heatstroke.
Always consider that heat index estimations are for light winds and places in the shade. A rise in the heat index by 15 Fahrenheit (8 Celsius) degrees may result from direct sunlight exposure.
Note: The heat index, also known as 'real feel' or 'apparent temperature', offers an insight into how hot it feels when we factor in moisture content. Factors such as metabolic variation, pregnancy, and physical activity play a role in one's impression of weather. Should you be directly under the sun, anticipate a possible increase in the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly important for children. Young ones generally face higher dangers than adults since they sweat less. Along with their large skin surface area compared totheir small bodies and increased heat production from their activities, the risks are heightened.
The natural cooling mechanism in humans involves perspiration, where the evaporation of sweat balances out excessive warmth. An increase in relative humidity hinders the body's normal cooling function by reducing evaporation, thereby decreasing the rate of body cooling and enhancing the sense of warmth. Overheating and potential dehydration arise when body heat gain eclipses its release capability.
