The study of 1,110 adults who use public transportation for work also found 51 per cent have chosen a more expensive commute in order to avoid germs.
And the same number have a ‘preferred regular spot’ they use on public transportation each day, for hygiene reasons.
Nearly eight in 10 (79 per cent) will also deliberately avoid holding on to handrails when on a bus, train or tube.
A spokesperson from Puressentiel, which commissioned the study, said, “Whilst
many of us have adapted and improved our commuting hygiene practices since the pandemic, from our research, we’ve seen that some are still unnecessarily contaminating their homes and others unbeknownst to them from their commute.
“The dangers of pollution outside aren’t new revelations, but many are still unaware of the dangers found indoors.
“In the UK 38 per cent use air fresheners to keep indoors air clean and 46 per cent burn candles.
“These cosmetic measures only add to the problem, it is far more important to address the root causes, improve air flow and adopt measures which remove or neutralize these indoor pollutants.
“The dangers of pollution outside aren’t new revelations, but many are still unaware of the dangers found indoors.”
The research also found 55 per cent avoid holding on to escalator handrails to lower their chances of picking up germs.
However, more than one in five (22 per cent) would not avoid a busy commute if they had a cough or cold, with 21 per cent of these saying they do not avoid touching grab rails on trains or tubes.
This could explain why 14 per cent of all those polled claim to wear disposable gloves during their commutes.
More than two thirds (67 per cent) said they are so concerned with personal hygiene they take a shower or bath when they get home.
This sentiment was further demonstrated as 69 per cent strongly believe you should not sit in or on the bed with outdoor clothes.
By contrast, 11 per cent conceded to not taking their outdoor shoes off when they get through the front door.
Footwear seemed to be a hot button issue, as 30 per cent said they would be offended if asked to remove their shoes in someone else’s home.
Almost one in six (15 per cent) admitted to not washing their hands when they get in, and 25 per cent feel it is unnecessary to change clothes when returning home from a busy commute.
A report from the European Lung Foundation identifies more than 900 different compounds found in indoor pollution, with some irritants occurring at levels two to five times higher than the air outside.
Helping to tackle unavoidable indoor pollution, laboratory research found that Puressentiel Purifying Air Spray reduced the number of viable cells of four common bacteria, including staphylococcus and E-coli, by a factor of 100,000.
The spokesperson added: “Although hygiene habits differ from person to person, we’re committed to raising awareness of indoor pollution and sharing ways this can be easily combated to improve our own health and those around us. ”
