Sustained activity might cause heatstroke.Factoring in the heat index, values are geared towards shaded areas with light breezes. Direct exposure to sunshine could lead to a heat index increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'real feel', is a metric representing the sensation of warmth when air temperature and moisture come together. A person's impression of weather can be shaped by several aspects, among them metabolic variations, pregnancy, and levels of physical activity. You should know that direct sun exposure can heighten weather effects, potentially elevating the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical for babies and toddlers. Children often overlook the need for breaks and fluid intake. Thirst is a late-stage sign of dehydration - hence, it is necessary to stay hydrated, especially during extended periods of physical activities.
The human body has a built-in cooling mechanism through perspiration; evaporating sweat dissipates the excess heat. Under conditions of high relative humidity, the rate of evaporation decreases. This results in the body retaining more heat than under conditions of dry air. Overheating and potential dehydration arise when body heat gain eclipses its release capability.
