Medline Plus writes that smoking is simply bad for your health. Nearly every organ of your body is harmed by smoking. 87 percent of lung cancer deaths are caused by cigarette smoking. Smoking is also responsible for many other cancers and health problems such as lung disease, heart and blood vessel disease, stroke and cataracts. By quitting smoking you can reduce your risk of these problems.
In an article on Dec. 31, 2012, Doctor's Health Press has reported, Smoking Can Be the Cause of Many Sleep Problems. If you’re a smoker, now there’s more motivation to quit after research has found that lighting up during the day could be keeping you awake at night. Researchers at the University Medical Center Freiburg in Germany have conducted a study in which they compared the quality of sleep in both smokers and non-smokers.
The researchers discovered that as for sleep patterns, in comparison with non-smokers, smokers, "slept for shorter periods of time, took longer to fall asleep, had higher rapid eye movement during sleep, experienced more episodes of sleep apnea, and experienced more disruptive leg movements." It was the conclusion of the researchers that smokers showed a number of insomnia-like sleep problems.
