At the beginning of this year I wrote about the link between asthma and insomnia.
In that post, I stated that smoking increases your risk of insomnia by 71%.
I recently did some more digging on the link between smoking and sleep disturbance. I found a study from 2008 that found the connection to be even more serious than previously thought.
According to research out of Johns Hopkins University School of Medicine, smokers are four times more likely to experience sleep disturbance compared to non-smokers.
Additionally, smokers don't get as much of the deepest, most restorative levels of sleep compared to non-smokers.
The study consisted solely of participants who had no other health conditions - meaning the study was able to specifically pinpoint smoking as the cause of disrupted sleep.
It's thought that nicotine withdrawal is the reason why smokers tend to experience poorer sleep health compared to non-smokers.
Nicotine is actually a double-edged sword - the stimulative effects of nicotine make it more difficult to fall asleep, and the nicotine withdrawal through the night helps contribute to sleep disturbance.
All the more reason to kick the habit, then.
