The flavors contained in the liquids of vapers dangerously vary the heart rate by disrupting the autonomic nervous system responsible for maintaining a normal rhythm in our heart. These disturbances also aggravate the risk of ventricular tachycardia.

- Flavored liquids in vapes create variations in heart rate.
- Ultimately, this can lead to ventricular tachycardia.
Although they are reputed to be less harmful than traditional cigarettes, vapers are still bad for your health. Researchers at the University of South Florida (USA) have found that the flavors present in vapers can damage heart cells. The results were published on November 20, 2020 in theAmerican Journal of Physiology-Heart and Circulatory Physiology.
Fruity tastes that mask the harmfulness
For many smokers, vaping is a good alternative to cigarettes. Less loaded with harmful products and with less addictive power, this device allows you to inhale steam by heating a liquid. This famous liquid can be more or less concentrated in nicotine, depending on the desire of its user. Above all, it is possible with the vaper to test a wide variety of fruity and/or sweet tastes, which gives it a recreational aspect. It is moreover on this recreational aspect, which one thinks without danger, that the manufacturers and the teenagers engulf themselves, persuaded to smoke a substance which is not harmful for health.
“Electronic flavored nicotine delivery systems, popular with teens and young adults, are not safeemphasizes Sami Noujaim, associate professor of molecular pharmacology and physiology at the Morsani School of Medicine at the University of South Florida. Taken together, our findings in cells and mice indicate that vaporization interferes with the normal functioning of the heart and can potentially lead to abnormal heart rhythms.”
For this experiment, the researchers subjected mice to 60 puffs of vanilla vape vapor for ten weeks, five days a week. In order to determine the changes induced on the heart, these mice were equipped with an electrocardiogram. In these mice, heart rate variability, i.e. fluctuations in the time interval between successive heartbeats, decreased compared to control mice, which only inhaled puffs of air instead.
Adverse effects on heart rate
What this experiment demonstrates is that inhaling the vapors alters heart rate variability by disrupting the autonomic nervous system, which normally regulates the beating of the heart. Similarly, vapor-exposed mice were more prone to ventricular tachycardia than control mice.
If these results were observed in mice, Sami Noujaim thinks the same phenomenon could occur in humans, although more preclinical studies need to be done to determine this. With these new studies, it would thus be possible to see the health risks of flavored vaping products and their long-term effects on health.
In some countries, flavored products for vaporizers and cigarettes have been banned, to prevent manufacturers from seducing younger people with tastes intended to mask the harmfulness of inhalants.
