What is humid definition?

Humidity is the amount of water vapor present in the air or any other gas. It is an important atmospheric variable that affects weather conditions, air quality, and human comfort. Humidity is measured in terms of relative humidity, which is the percentage of water vapor present in the air compared to the maximum amount that the air can hold at the same temperature and pressure. High humidity makes the air feel warmer than it actually is because water vapor slows down the evaporation of sweat from our skin, which is our body's way of cooling down. Very high humidity can also cause discomfort, difficulty breathing or lead to mold growth. Dry air, on the other hand, can dry out our skin and respiratory tract. Maintaining optimal humidity levels are critical for a variety of applications such as industrial processes, museums/artifacts preservation, crop yields and indoor comfort.
