Effect of humidity

Benefits of air conditioner humidity control for sleeping environments demonstrated

Humidity control is critical in creating
a comfortable sleeping environment.

When humidity in the room is close to 80%, perspiration does not evaporate easily, and body temperature cannot be adjusted properly, which makes it difficult to fall asleep and makes you feel uncomfortable when you wake up.

Controlling the humidity at 40–60% is important for a good night’s sleep. Air conditioner humidity control was shown to improve sensations of alertness, motivation, mood, calmness, and appetite upon waking. Humidity control is essential for restful sleep.
