Here's a breakdown of what makes air "muggy":
* High humidity: This means there's a lot of moisture in the air, making it feel heavy and dense.
* Warm temperatures: While not strictly necessary, warm temperatures enhance the muggy feeling.
* Lack of wind: Still air traps moisture, intensifying the muggy sensation.
Muggy weather can make people feel uncomfortable, sticky, and sweaty. It can also contribute to the growth of mold and mildew.
