STUDY: Nicotine would have an impact on sleep and prevent deep sleep.

This is a new study from Switzerland that has sown trouble on smokers, vapers and more generally on nicotine consumption. Indeed, the consumption of nicotine could adversely affect the quality of sleep, as revealed by a study conducted by specialists from the CHUV in Lausanne.


SMOKING CERTAIN, STILL TO CHECK FOR THE VAPE!


The rest of smokers would be less deep and less restorative than that of non-smokers. In any case, this is supported by research carried out by internal medicine specialists from the CHUV in Lausanne who recently published their results in the online journal. Sleep medicine. Note that they relied on rigorous statistical analysis of data from the Lausanne sleep cohort CoLaus / HypnoLaus.

Of the 3200 participants in the study, classified into three categories - smokers, former smokers and non-smokers - nearly half of them agreed to undergo polysomnography, as pointed out Minh Khoa Truong, assistant physician in the pneumology department of the CHUV and first author of this article on the impact of smoking on sleep.

 » This is a test that analyzes the physiology of sleep with sensors that are placed on you while you sleep. “, He underlines at the microphone of the CQFD program, specifying that this process makes it possible in particular to observe the respiratory movements, the oxygen in the blood and the cerebral activity of the patient.

Main result of the study: the microstructure of sleep is not the same between a smoker and a non-smoker, as the specialist notes. " That is to say that smokers have brain activity during sleep that is faster than in non-smokers, approaching more wakefulness than deep sleep.". Note that the amount of cigarettes smoked during the day would also have an effect on sleep. " In other words, the more you smoke, the less deeply you sleep“, He notes.

Nicotine is thought to be the main responsible for this mechanism. " We know that nicotine has an exciting effect. It activates the centers of awakening during sleep and deactivates the centers that promote sleep “, Continues the doctor. According to him, the electronic cigarette, in which nicotine is present, therefore does not help. " It would also have an impact on sleep, but that remains to be studied more precisely. »
