Question: 1 / 400

What effect does nicotine have on sleep?

Promotes restful sleep

Causes vivid dreaming

Increases insomnia

Nicotine is known to have a significant impact on sleep patterns, primarily by increasing the likelihood of insomnia. As a stimulant, it can disrupt the natural sleep cycle, making it difficult for individuals to fall asleep and stay asleep. Nicotine can alter the time it takes to fall asleep, reduce total sleep time, and diminish the quality of sleep by reducing deep sleep and increasing lighter sleep stages.

Chronic nicotine use, whether from smoking or other tobacco products, can lead to longer-term sleep disturbances, worsening overall sleep quality, and contributing to feelings of fatigue during waking hours. This tumultuous effect on sleep is particularly pronounced in individuals who use nicotine before bedtime or consume it regularly. Consequently, understanding this impact is crucial for polysomnographic technicians as they evaluate sleep studies and patients' sleeping habits.
