Remember, the physical withdrawal phase of quitting tobacco is a temporary condition. Your sleep patterns will return to normal soon, providing you didn’t have insomnia before cessation. Smokers spend more time in a light sleep. Non-smokers spend more time in a deep sleep, allowing them to feel more awaken the next day. A reason for this is nicotine and its impact on the brain. Smoking cigarettes impairs sleep quality, possibly because of nicotine withdrawal, according to a study in the February issue of Chest, the journal of the American College of Chest Physicians. The study is among the first to isolate the effects of smoking on sleep.
Cigarettes contain nicotine that affects sleep. It is a stimulant that keeps you awake. But smokers are not aware of this fact. Rather they claim that a puff of cigarette smoke makes them feel calmer and helps them relax. On the contrary, nicotine stimulates the mind and the body. It interferes with the body’s ability to fall and stay asleep. Nicotine is a stimulant drug that once it wore off threw the smoker into a physiologically depressed state. The availability of objective data on sleep architecture, with self-reported information on smoking status, provides an opportunity to characterize sleep structure among current, former, and never smokers in a large community-based sample.
