Records show heat index calculations are tailored for shaded regions and mild winds. The heat index has the potential to rise by 15 Fahrenheit (8 Celsius) degrees with direct sunshine exposure.
Note: The heat index, also known as 'feels like' or 'apparent temperature', is a value derived by merging air temperature with the humidity to convey how the climate feels. One's perception of temperature is subjective, varying based on their activity and individual heat perception, influenced by factors like wind, clothing, and metabolic variations. Take note that direct exposure to the sun can increase the felt temperature, possibly adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are highly critical 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.
The body's self-cooling mechanism is rooted in perspiration, where evaporating sweat cools down excessive warmth. 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. When the body is unable to balance heat gain, its temperature elevates, which may induce thermal illnesses.

Always safeguard yourself; without protection, skin and eyes can get damaged instantly. Stay in the shade and avoid direct Sun exposure from 10 a.m. to 4 p.m., a period when UV radiation is particularly strong, noting that parasols or canopies may not offer total sun protection. In bright sunlight, prioritize sunglasses that grant protection from UVA and UVB radiation.
