Heat index

Throughout July, the heat index is evaluated at a fiery hot 95°F (35°C). Undertake enhanced precautions, heat exhaustion and heat cramps are possible risks. Continuous activity could trigger heatstroke.

Note: The heat index, also known as 'real feel' or 'apparent temperature', is found by incorporating humidity levels into the air temperature measurement. One's perception of weather can be shaped by other factors, involving metabolic differences, pregnancy, and physical exertion. Keep aware, the sun, when shining directly, can intensify the heat experience, pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values are primarily vital for children. Younglings frequently fail to recognize the requirement to rest and rehydrate. Thirst emerges late in dehydration - it is imperative to keep hydration levels high, particularly during extended physical exertions.
Perspiring is the body's way of cooling down, particularly by allowing sweat to evaporate and take the heat with it. Under conditions of high temperature and humidity (enhanced heat index), sweat production is compromised, exacerbating the sensation of warmth. If heat absorption exceeds the body's cooling ability, body temperature can elevate, resulting in potential thermal illnesses.
