Heat index

Heat index data is primarily for areas with shade and subjected to light winds. Direct sunlight might lead to a heat index increase by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'real feel', gauges the sensation of temperature factoring in the air's moisture content. Additional elements encompassing metabolic differences, the degree of physical activity, and attire can impact the individual's perception of temperature. The sun, when shining directly, can have a significant impact on the perceived temperature, increasing the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly meaningful for babies and toddlers. Children often fail to understand the importance of rest and rehydration. Thirst is a late manifestation of dehydration - hence, it is crucial to stay hydrated, especially during ongoing physical activities.
The human body normally cools itself by perspiration, as evaporated sweat carries heat away from the body. When relative humidity is on the rise, it curtails evaporation, thereby reducing the heat elimination from the body and causing the feeling of being excessively hot. Increasing body temperatures can be a precursor to dehydration if the body can't shed the extra heat.
