Continuous activity could lead to heatstroke.The metrics for the heat index are tailored for both shady environments and light winds. If exposed to direct sunlight, the heat index could climb by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'feels like', determines the feeling of heat when you account for the relative humidity. This impact is subjective, influenced by the person's physical activity and individual heat perception, affected by factors including wind, attire, and metabolic differences. When directly under the sun, the weather's impact can intensify, possibly boosting the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for babies and toddlers. Children often overlook the necessity for resting and fluid replenishment. Thirst is a late sign of dehydration - thus, it is critical to stay hydrated, especially during extended periods of physical activities.
By perspiring, the human body can shed its excessive warmth since evaporated sweat cools it off. 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.
