Heat index

July's average heat index is estimated at a fiery hot 100.4°F (38°C). Take more preventive steps, risk of heat exhaustion and heat cramps is elevated. Long activity may culminate in heatstroke.
Understanding the heat index involves considering values for shaded locales with light wind. Exposure to direct sunlight may make the heat index values climb by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'real feel', stands as a testimony to how temperature and humidity combine to impact our sense of warmth. The individual's impression of temperature can be affected by numerous factors such as metabolic variations, physical exertion, and attire. Direct sunlight can potentially raise the heat index by 15 Fahrenheit (8 Celsius) degrees, so it's crucial to consider. Heat index values are especially vital to children. Children often lack awareness of the importance of taking breaks and rehydrating. The feeling of thirst is a late indication of dehydration, so maintaining hydration, especially during long periods of physical activity, is critical.
In response to overheating, the human body perspires to cool down, mainly through the evaporation of sweat. Under conditions of increased relative humidity, the evaporation rate lessens, causing the body to retain more heat than under less humid conditions. Overheating and potential dehydration arise when body heat gain eclipses its release capability.
