Heat index

The heat index value during June is estimated at a torrid 36°C (96.8°F). Exercise enhanced safety steps, heat cramps and heat exhaustion are probable. Heatstroke could be a result of sustained activity.
Data suggests that the heat index is set for environments in shade and with a light wind. Heat index values can rise by 15 Fahrenheit (8 Celsius) degrees when in direct sunlight.
Note: The heat index, also known as 'feels like' or 'felt air temperature', combines air temperature and relative humidity to represent a human perceived temperature equivalent. Additional factors encompassing metabolic differences, the level of physical activity, and clothing can impact the individual's perception of temperature. Consider that direct sun exposure can intensify the felt heat, adding potentially 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are highly critical for babies and toddlers. Juveniles are regularly less conscious of the need to recuperate and rehydrate. Thirst is a tardy symptom of dehydration - hydration, especially during lengthy physical activities, should be maintained.
The physiological way the human body responds to excessive heat is by inducing perspiration, using sweat evaporation as a cooling mechanism. In high relative humidity, the body's ability to evaporate heat is diminished, resulting in a heightened feeling of warmth. When the body is unable to balance heat gain, its temperature elevates, which may induce thermal illnesses.
