Sleeping in AC all night: Comfort or health risk?

Health concerns extend beyond immediate comfort issues. The body’s natural temperature drops between 4 and 6 am. When this is combined with prolonged cold air exposure, it can lead to skin problems, including dryness and itching. This further exacerbates acne, poor skin barrier, and low moisture levels. Skin with low moisture is susceptible to wrinkles, dullness, and dark spots over time.
