Smoking Increases Insomnia Risk in a Dose-Dependent Manner
Smoking disrupts sleep by increasing insomnia risk nearly twofold for current smokers (OR=1.78), with heavier consumption leading to progressively greater odds through nicotine's interference with sleep architecture.
- Current smokers have nearly twice the odds of insomnia (OR=1.78) compared to non-smokers
- Risk escalates with increasing daily cigarette use, stronger in heavy smokers
