A new study suggests it’s possible to achieve better sleep quality if you don’t smoke.
In the study published in the journal Sleep, researchers looked at the impact of electronic cigarette use on sleep.
They found that e-cigarettes, while less effective than regular cigarettes, may be able to improve sleep quality in people who had smoked for longer periods of time.
Study author Dr Matthew Dolan said it was surprising that nicotine replacement therapy (NRT) was associated with improved sleep.
“The only thing that we found was that efCigs may help improve sleep by reducing nicotine withdrawal symptoms, but we don’t know whether that is true or not,” he said.
“We don’t really know what effects nicotine replacement could have on sleep.”
E-cigarettes are nicotine-delivery devices, which deliver nicotine via a cartridge.
The devices contain nicotine patches and cartridges which contain nicotine.
“It is well known that people who use e-cigs report more sleep quality when they use them, but there is little data on how e-cig use affects sleep,” Dr Dolan explained.
“Our research found that nicotine-containing e-liquids had an effect on sleep in people with sleep problems, including those who used them for more than four hours a night.”
The study found that people with better sleep were more likely to also use e,liquid replacement.
“People who smoke for a long period of time and for more frequent use have a lower quality of sleep,” said Dr Dola.
“E-cigarette users had lower quality sleep when compared to people who smoked for shorter periods of the day, or for less than four or five hours a day.”
Dr Dolan believes that e cigarettes may help to boost quality of life and improve sleep, especially in those with chronic sleep problems.
“If you use a device, you’re using a lot of nicotine and you’re also getting a lot per unit of nicotine, so it’s an ideal device for helping people with chronic and sleep problems,” he explained.
E-cigarettes are currently being marketed as a safer alternative to smoking, but their impact on health is still unknown.
“In our study, we did not find any relationship between e-cigarette use and sleep quality,” Dr Gudmundsson said.
“Our results should be interpreted with caution, but our results suggest that e‐cigarette use may help people with severe sleep problems.”
Dr Gudsson said there is a “possibility that e cigarette use may lead to less sleep quality.”
“The main issue is that e‑cigarette use could potentially lead to more tobacco consumption, and more tobacco exposure,” he added.
“Therefore, the longer people smoke, the more they can consume.”
Dr David Nutt, professor of psychiatry at King’s College London, said there were also “many unknowns” about the effect of e-vapor on the brain.
“While e-tobacco has been shown to increase the risk of lung cancer and cardiovascular disease, we do not yet know if this risk is dose-related or cumulative,” he told BBC News.
“What we do know is that it increases the risk for depression, anxiety, and substance abuse.”
Dr Nutt said the evidence was mixed about whether e-liquid had any long-term impact on the brains of people.
“I think the evidence that has been collected suggests that e cigs have been associated with reduced sleep, but this is just a small study,” he commented.
“There are other studies that have shown that e liquid does not seem to have a negative impact on sleep quality.”
But there are still many unknowns, so I think we should not make too many assumptions about e-juice.
