Note: The heat index, also known as 'feels like' or 'felt air temperature', is derived by integrating air temperature with the existing relative humidity to express the perceived warmth. A person's impression of weather can be affected by numerous aspects, among them metabolic variations, pregnancy, and activity levels. Should you be directly under the sun, anticipate a possible increase in the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular importance for children. Young ones generally face higher dangers than adults since they sweat less. Along with their large skin surface area compared totheir small bodies and increased heat production from their activities, the risks are heightened.
To achieve cooling, the human body employs perspiration, relying on the subsequent evaporation of sweat. With a lot of moisture in the air, the evaporation process is not as effective, and the body does not cool down as efficiently, creating a perception of overheating. Overheating and dehydration threats arise when heat gain goes beyond what the body can comfortably shed.
