The Evolving E-Cigarette: A Comparison Narrative of Cigarette Smoke and E-Cigarette Vapour on Sleep

Recent development of ‘e-cigarettes’ has increased the utilization by the common population, under the assumption of it being a safer alternative compared to conventional cigarettes. However, the harmful biological effects of e-cigarettes, or most commonly called vaping, are still not clear. This review aims to highlight the effect of conventional cigarettes on one’s sleeping patterns and quality. The studies reported in this review were collected from the databases that included PubMed, ScienceDirect, Hindawi, ResearchGate, and AHA journals from 1994-2022. Studies that focussed on the effects of smoking on other aspects of one’s health. Separate literature searches were conducted to analyse sleep quality among people that smoked cigarettes and people who used a vape. Literature reviews showed cigarette smoking caused a reduction in sleep quality and also an increased risk of sleep-related disorders. A review of articles concerning the association between vape and sleep also showed similar results, with vape users reporting shortened and poorer sleep quality compared to non-users. Data from this article can prove useful in shedding light on the deleterious impact of vape on sleep and overall general health, as the common notion of e-cigarettes being an acceptable and safe substitute is widely practiced among the younger population.
