A new study offers a fresh incentive to kick the nicotine habit: Quitting smoking can improve your sleep, researchers say.
Researchers from the University of Florida and Research Triangle Park looked at the association between sleep and smoking in a sample of nearly 5,000 U.S. adults. They found that nearly 12 percent of current smokers have trouble falling asleep, almost 11 percent wake in the night and 9.5 percent wake too early in the morning. The figures for nonsmokers were much lower, and researchers saw that for those who gave up smoking, their sleep improved significantly.

Findings, announced last week, appeared online in the journal Psychology, Health & Medicine.
Prior research has also found that smokers may get fewer hours of sleep and have less restful slumber than nonsmokers, according to a German study published last year in the journal Addiction Biology. In the survey of nearly 1,100 smokers, 17 percent said that they slept fewer than six hours a night, while 28 percent reported "disturbed" sleep quality.
