The heat index for July is estimated at a blazing hot 116.6°F (47°C). Prudent: Heat cramps and heat exhaustion are likely. Heatstroke becomes imminent with sustained exertion.Research indicates the heat index considers values in shaded locales and with light winds. Direct sunlight might lead to a heat index increase by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', is derived by integrating air temperature with the existing relative humidity to express the perceived warmth. Factors such as metabolic variations, being pregnant, and physical activity can impact an individual's weather perception. When you're directly under the sun's rays, remember that the heat index may surge by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly important for children. Children frequently do not understand the need for recuperation and hydration. Thirst, being a late manifestation of dehydration, underlines the need to hydrate frequently, especially when engaging in prolonged physical exercises.
The primary way humans combat excessive warmth is by perspiring, letting sweat evaporate and cool the body. When air moisture content is high, the cooling process through evaporation is not as efficient, leading to an ineffective body cooling process and a feeling of overheating. When heat gain surpasses the level the body can shed, body temperature begins to increase, and consequently, overheating and dehydration can occur, with varying severity.
