Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', ties air temperature with relative humidity to produce the perceived temperature sensation. A person's impression of weather can be affected by numerous aspects, among them metabolic variations, pregnancy, and activity levels. Direct sun exposure is noteworthy in its ability to escalate the felt temperature, potentially adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are particularly meaningful for babies and toddlers. 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.
Evaporating sweat, thanks to perspiration, acts as a natural air conditioner for the human body. High relative humidity reduces the evaporation rate, resulting in a lower heat removal rate from the body, causing the perception of being overheated. Rising body temperatures resulting from an imbalance in heat absorption can lead to potential thermal issues.

Enhance your sun protection with tightly woven, yet airy clothing.
