Continued exertion can result in heatstroke.The standards for the heat index are set for locations in shade and under light breezes. Exposing to direct sunshine may enhance heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'feels like', is a value derived by merging air temperature with the humidity to convey how the climate feels. One's weather perception can be influenced by a range of factors including metabolic differences, being pregnant, and their level of physical activity. Direct exposure to the sun's rays can enhance the felt temperature, increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely vital to babies and toddlers. Young children are generally more endangered than adults, as they usually less sweat. And also, due to larger skin surface relative to their small bodies and higher heat production as a result of their activity.
Perspiring is a crucial mechanism for the human body, allowing it to release excessive warmth through evaporating sweat. When relative humidity increases, the body's capacity to evaporate heat decreases, leading to a heightened sense of warmth. If the body retains more heat than it can expel, the increasing temperature can lead to heat-related conditions.
