August's average heat index is computed to be a fiery hot 100.4°F (38°C). Undertake enhanced precautions, heat exhaustion and heat cramps are possible risks. Continuous activity could trigger heatstroke.Take into consideration that the heat index values are calculated for shade and light wind conditions. The heat index may scale up by 15 Fahrenheit (8 Celsius) degrees with direct sun exposure.
Note: The heat index, also known as 'felt air temperature' or 'real feel', stands as a testimony to how temperature and humidity combine to impact our sense of warmth. The influence of weather is personal, differing among a variety of individuals based on differences in body mass, stature, and the level of physical activity. Take note that direct exposure to the sun can increase the felt temperature, possibly adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are primarily vital for children. Young people are generally more susceptible than adults because they perspire less. Furthermore, their proportionally larger skin surface to their petite bodies and the increased heat output from their actions add to the risk.
As a reaction to high temperatures, the human body begins to perspire, using the evaporation of sweat to lower its temperature. When the relative humidity is high, the evaporation rate is reduced. The warmth is removed from the body at a lower rate, causing the body to retain more heat than it would in dry air. The body is at risk of dehydration and related complications when it fails to shed excessive heat.
