Understanding Relative Humidity and Its Impact on Human Cooling Mechanisms

Relative humidity is a key weather factor that limits the body's ability to cool itself through sweat evaporation on hot days.

When humidity is high, sweat cannot evaporate effectively, leading to heat accumulation in the body, which can pose significant health risks.

Warm air holds more moisture than cool air, meaning that even if absolute moisture levels are constant, relative humidity changes with temperature fluctuations.
