Do Not Smoke While Wearing a Mask: Here’s Why


“The study suggests that smoking any tobacco product has become even more hazardous during the COVID-19 pandemic because of the need to wear a mask for long hours,” mentioned examine writer Professor Ignatios Ikonomidis of the Nationwide and Kapodistrian College of Athens, Greece. “Prior research has shown that impaired vascular function is linked with heart problems and premature death.”

The examine targeted on conventional (flamable) cigarettes and non-combustible cigarettes, additionally known as “heat not burn” or “heated” tobacco merchandise. Non-combustible cigarettes include tobacco which is electronically heated to a decrease temperature than a combusted cigarette, delivering an inhalable aerosol containing nicotine. The examine didn’t embody e-cigarettes (additionally known as vaping) which electronically warmth a liquid containing nicotine to create an aerosol that’s inhaled.


The researchers investigated the degrees of exhaled carbon monoxide in people who smoke whereas carrying a masks throughout working hours and in contrast it to carbon monoxide ranges throughout days off and not using a masks. In a second step, the researchers examined whether or not the change in carbon monoxide publicity was accompanied by impaired blood vessel operate.

The examine included 40 people who smoke of typical cigarettes, 40 unique warmth not burn cigarette customers and 40 non-smokers with related age and intercourse who had been medical personnel in a college hospital. People with recognized heart problems, hypertension, diabetes, dyslipidaemia, power kidney illness or atrial fibrillation had been excluded as these situations might have an effect on vascular operate.

The researchers measured exhaled carbon monoxide after a deep breath and markers of vascular operate (pulse wave velocity, augmentation index and central systolic blood strain). Baseline assessments had been executed early within the morning after sleeping and not using a masks to acquire values after an extended interval with out smoking. Individuals had been randomized to a second evaluation after both an eight hour shift carrying a masks or eight hours off and not using a masks. They then crossed over to a 3rd evaluation after both eight hours off with no masks or eight hour working with a masks.

The typical age of members was 45 years and 72% had been ladies. The same variety of flamable or non-combustible cigarettes had been smoked throughout masks and non-mask durations. In typical cigarette people who smoke, exhaled carbon monoxide elevated from 8.00 elements per million (ppm) at baseline to 12.15 ppm with no masks and 17.45 ppm with a masks. In non-combustible cigarette people who smoke, exhaled carbon monoxide elevated from 1.15 ppm at baseline to 1.43 ppm with no masks and a pair of.20 ppm with a masks. Amongst non-smokers, exhaled carbon monoxide didn’t differ between the baseline, non-mask and masks durations.

Professor Ikonomidis mentioned: “Compared to smokers of combustible cigarettes, non-combustible cigarette users had lower baseline carbon monoxide levels and smaller increases in vascular damage while wearing a mask. Nevertheless, the findings show that smoking any tobacco product while wearing a mask may further impair blood vessel function compared to non-mask periods, at least partly due to greater re-inhalation of carbon monoxide and/or vapour rich in nicotine. The results provide even more impetus for all smokers to kick the habit.”
