Heat index

For most parts of June, the heat index is evaluated at a sweltering 95°F (35°C). Extra safeguards are necessary to prevent heat exhaustion and heat cramps. Prolonged activity might cause heatstroke.
Heat index values are typically calculated for conditions of shade and a light breeze. Exposure to the direct sun might augment heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'felt air temperature', is an index that combines air temperature and relative humidity to determine the human-perceived temperature equivalent. Elements such as metabolic variations, pregnancy, and physical exertion can influence one's weather perception. Consider the fact that direct sun exposure can influence how hot one feels, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly important for children. Young ones often do not realize the necessity to rest and replenish their fluids. Thirst is a delayed indication of dehydration - keeping hydrated, particularly in prolonged physical activity, is crucial.
The body's self-cooling mechanism is rooted in perspiration, where evaporating sweat cools down excessive warmth. Heightened relative humidity interferes with the body's usual cooling mechanism by reducing evaporation, subsequently decreasing the body's cooling rate and increasing the sensation of heat. Heat absorption that surpasses the body's shedding capability can lead to overheating and varying levels of dehydration.
