Smoking can negatively affect sleep quality in several ways. Nicotine is a stimulant that can make it harder to fall asleep and stay asleep throughout the night. Smokers may experience disrupted sleep patterns, frequent waking, and reduced overall rest. Poor sleep can contribute to fatigue, reduced concentration, and lower productivity during the day. Research suggests that people who quit smoking often experience improvements in sleep quality over time. This topic provides an opportunity to discuss how tobacco use influences sleep and why adequate rest is important for maintaining overall physical and mental health.
