Throughout September, the heat index is appraised at a sweltering 96.8°F (36°C). Ensure heightened precautions, risk of heat cramps and heat exhaustion is significant. Sustained activity could provoke heatstroke.Understanding the heat index involves considering values for shaded locales with light wind. The presence of direct sunlight can raise the heat index values by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'apparent temperature', quantifies the warmth felt when relative humidity is considered. Elements of metabolic variation, physical activity, and clothing contribute to the effect of temperature on an individual. When in direct sunlight, one should be cautious as it can raise the heat index by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly meaningful for babies and toddlers. Young ones often do not realize the necessity to rest and replenish their fluids. Thirst is a delayed indication of dehydration - keeping hydrated, particularly in prolonged physical activity, is crucial.
The human body normally cools itself by perspiration, as evaporated sweat carries heat away from the body. Greater relative humidity lessens the rate of evaporation, thus decreasing the body's heat dispersal, which gives rise to a sensation of overheating. Heat-related complications, like dehydration, can manifest if the body's heat gain exceeds its dissipation capacity.
