Heat index

The average heat index in July is computed to be a fiery hot 39°C (102.2°F). Adopt special protective actions against heat exhaustion and heat cramps. Long-duration activity risks heatstroke.
Take into consideration that the heat index values are calculated for shade and light wind conditions. An exposure to direct sunlight may lift the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'feels like', evaluates the perceived heat by adding the effect of moisture in the air. Elements such as metabolic variations, pregnancy, and physical exertion can influence one's weather perception. Being under direct sunshine can magnify the heat experience, possibly pushing up the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are largely significant for babies and toddlers. 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.
Perspiration is the human body's physiological response to high temperatures and is an attempt to lower body temperature through evaporation of sweat. 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. Overheating can ensue when the body accumulates more heat than it can release, and dehydration severity may vary.

Put into effect every precaution of importance, unprotected skin and eyes may get burns swiftly. The Sun's UV radiation is at its strongest between the hours of 10 a.m. and 4 p.m. Minimize direct exposure to the sun during this period. For effective sun eye protection, rely on sunglasses certified for UVA and UVB resistance. Following every swim or outdoor workout, a sunscreen with an SPF of not less than 30 should be liberally applied and re-applied frequently, even on overcast days. Stay vigilant! UV rays get a boost in intensity due to sand and water reflections.
