Study finds smoking may disturb a good night’s rest

Rochester, NY – Smoking disrupts the body’s circadian rhythms, which could result in poor sleep, cognitive dysfunction and mood disorders, according to a new study from the University of Rochester Medical Center.

In a study involving mice, researchers found that tobacco smoke interfered with the circadian rhythms of the lung and brain. Similar changes were detected in the tissue of human smokers with chronic obstructive pulmonary disease, a press release states. Another finding was that mice were significantly less active after being exposed to smoke.

The study was published in the January issue of the FASEB Journal.
