High humidity is commonly considered to be a relative humidity level above 60%. When humidity levels reach this percentage, it can create a muggy and uncomfortable environment, making it feel significantly warmer than the actual temperature. This happens because high humidity impairs the body’s ability to cool itself through the evaporation of sweat.
In many regions, especially tropical and subtropical areas, humidity levels frequently exceed this threshold, leading to discomfort during the summer months. Additionally, in terms of health and comfort, relative humidity above 70% is often viewed as excessive.
Understanding humidity levels is essential not only for personal comfort but also for various applications, such as agriculture and weather forecasting. Maintaining optimal indoor humidity, typically between 30% and 50%, is crucial for health and well-being.
