Los Angeles Sleep Specialist Dr. Dan Naim Comments on New Study Which Finds Smokers Have More Disturbed Sleep

Along with the number of chronic diseases linked to cigarette smoking, smokers also experience problems such as shorter sleep duration and less restful sleep, as determined by a recent study. Quitting the habit is one of the most important things a smoker can do for better sleep and overall health, said Dr. Dan Naim of the Los Angeles Sleep Study Institute.

Because smoking has a negative effect on sleep, it has an indirect impact on day to day functioning

Increased risk of stroke, emphysema, cancer, and many other chronic diseases are associated with tobacco use, but disturbed sleep is a daily occurrence for many smokers, as well. A new German study published in the October issue of the journal Addiction Biology found that smokers experience impaired sleep quality and shorter sleep duration. Board-Certified Los Angeles Sleep Specialist Dr. Dan Naim explains how nicotine can negatively impact sleep.

The new research found that of 1100 smokers surveyed, 17 percent got less than six hour of sleep per night and more than one-quarter reported disturbed sleep quality. By comparison, of the 1200 non-smokers surveyed, only seven percent slept less than six hours per night and 19 percent reported disturbed sleep. Results were measured by a survey called the Pittsburgh Sleep Quality Index, which asked volunteers questions regarding reasons for trouble sleeping at night or staying awake during the day.

Similar to caffeine, nicotine is a stimulant. Nicotine is a highly addictive, harmful chemical which has a short half-life, or the time it takes for the substance to lose half of its potency, of approximately 60 minutes. Because many smokers have their final cigarette of the day before going to sleep, it can result in a more alert feeling, causing restlessness. After about six hours, all nicotine has left the body, which can interrupt the deeper phases of sleep and keep a person from reaching the more restful stages of sleep.

Another 2012 study published in the journal Sleep Medicine found that smokers showed sleep impairments similar to those experienced during insomnia, such as shorter sleep period time, longer time to fall asleep, sleep-disorder breathing, and leg movements.

“Because smoking has a negative effect on sleep, it has an indirect impact on day to day functioning,” said Dr. Naim. “Smokers have a high likelihood of developing insomnia, which is another good reason to quit smoking. In the process of quitting smoking, nicotine withdrawals and insomnia are the most common reasons why smokers relapse, but sleep will gradually improve, along with its restorative benefits.”
