Can you get drunk through your toes?

Can you get drunk by dunking your feet in alcohol?  A strange question you might think, but an interesting one.  I recently wrote a post responding to some rather outlandish claims made on the Jeremy Vine radio show, and one of them was that we absorb 14 kg of toxins annually through our skin into our bloodstream.  This one was so questionable that I started a quest to Ask for Evidence (a campaign run by the charity Sense About Science) on the subject.  It’s thrown up a up a number of interesting bits and pieces, and there will be more to come on this topic.

Feet being submergedBut in the meantime, absorption of chemicals through skin was on my mind as I was listening to the Ask the Naked Scientists podcast.  A question about methylated spirits came up.  In his answer, Dr Chris Smith referred to a rather brilliant piece of work by some Danish scientists.

It was published in the British Medical Journal, and here’s the title: Testing the validity of the Danish urban myth that alcohol can be absorbed through feet: open labelled self experimental study

Now if that doesn’t make you want to read on, I don’t know what will.  It would appear that along with stories of suicidal architects and families being duped on holiday, there is a popular Danish urban legend that you’ll become drunk if you submerge your feet in alcoholic drink.

So late in 2010 three researchers – you can listen to an interview with one of them here – decided to test this theory, using themselves as subjects (three isn’t a very robust sample size, but perhaps they didn’t have the resources to recruit more volunteers – vodka is expensive after all).

They abstained from alcohol for 24 hours before the test to ensure that there was none in their blood, and carefully exfoliated their feet with loofas to remove dry skin.  Their blood was monitored through a venous line and a ‘before’ blood alcohol level was recorded.

And then they submerged their feet in washing up bowls filled with the contents of three 700 mL bottles of 37.5% alcohol vodka, for three hours.

What happened?  Sadly, very little.  Their blood alcohol levels stayed below the detection limit for the whole three hours.  They didn’t get drunk, their self-confidence didn’t suddenly improve, they didn’t become noticeably more chatty and no one had the urge to spontaneously hug anyone else (all these things were monitored).

It seems fairly conclusive that you can’t get drunk through your skin.  Now, the alcohol is vodka is ethanol, C2H5OH.  It’s quite a small molecule, and if it can’t get into your bloodstream when you submerge your feet right in it, then I think that really does call into question the likelihood that 14 kg of ‘toxins’ are sneaking past our skin’s defences every year.

The researchers, by the way, published their work in December 2010, and called it the: Percutaneous Ethanol Absorption Could Evoke Ongoing Nationwide Euphoria And Random Tender Hugs study.  Who says scientists don’t have a sense of humour?
