Soap
So what about the instructions on hand-washing during COVID?

When
James Hamblin tells people he has not used soap in the shower for five
years, they tend not to hold back in expressing their disgust. “It’s one
of the few remaining things for which we feel fine telling someone that
they’re gross,” he says. “It’s amazing to me, honestly.”
Yet despite people’s “clearly moralising
judgments”, Hamblin is no hygiene slouch. Even pre-pandemic, he made a
point of washing his hands with soap. He is, after all, a doctor who
lectures at the Yale School of Public Health and a medical writer and
podcaster for the US magazine the Atlantic. At 37, he looks so youthful that he still gets compared to the fictional child doctor Doogie Howser.
But eschewing soap on your pits and bits does
raise awkward technical questions, more on which after some context.
Hamblin’s minimalist showering habits evolved gradually, after he
relocated from California to a studio apartment in Brooklyn, New York,
to pursue a writing career. He needed to save time, money and space.
Simultaneously, he says: “I started learning about emerging microbiome
science and decided to try going all-out for a bit.”
Even if you have not yet read up on our microbiomes
– the trillions of microbes that lead symbiotic lives with humans,
colonising our skin and our guts – you may have spotted vague statements
such as “microbiome-gentle” printed on bottles of shower gel. This
because microbiologists – and brands – are learning more and more about
the complex relationship we have with our germs. These include their
starring roles in developing our immune systems, protecting us from
pathogens (by creating antimicrobial substances and competing with them
for space and resources) and lessening the likelihood of autoimmune
conditions such as eczema. So, there is a growing awareness that
scrubbing them off, along with the natural oils on which they feed, or
dousing them with antibacterial products may not be the best idea after
all.
Hamblin’s new regime got him thinking about
modern notions of cleanliness, what is natural and how these two issues
are, frankly, all over the shop. Stigmatism of body odour began as an
advertising strategy that helped quadruple the sales of Lifebuoy soap in
the 20s. A century later, we still live in fear of anyone detecting the
slightest hint of BO on us. We are more perfumed, moisturised and
exfoliated than ever.
Yet despite advances in skincare and modern
medicine, conditions such as acne, eczema and psoriasis, as well as
other autoimmune diseases, have been rising steadily. Also, while we
attempt to appear squeaky clean, research has revealed that many of us don’t wash our hands properly
– or at all – when it matters most: before eating and after going to
the toilet. (That said, awareness of the importance of handwashing has
certainly risen as a result of Covid-19.)
“It’s all mixed up right now, right?” says
Hamblin, who set out to explore these paradoxes in perceived cleanliness
in his book Clean: The New Science of Skin and the Beauty of Doing Less.
He says the key to the success of his experiments, which saw him all
but give up deodorant, was his “slow-fade” approach. “As I gradually
used less and less, I started to need less and less,” he writes. “My
skin slowly became less oily, and I got fewer patches of eczema. I
didn’t smell like pine trees or lavender, but I also didn’t smell like
the oniony body odour that I used to get when my armpits, used to being
plastered with deodorant, suddenly went a day without it.” As his
girlfriend put it, he smelled “like a person”.
It is not that we were unaware of bodily odours
before “BO” was coined, but Hamblin thinks our natural smells are far
more nuanced and informative than we give them credit for. “We know from
historical writings that certainly people smelled bad. We didn’t just
accept all smells,” he says. “Now, if someone smells sweaty or of
anything less than soap, perfume or cologne, we think of that as being
unclean.”
Hamblin started to notice that he smelled less
pleasant when stressed. He interviewed a researcher who could train dogs
to sniff out cancer in humans, while lovers he spoke to told him they
thought the way their partner smelled naturally was good. He writes:
“The hundreds of subtle volatile chemical signals we emit may play roles
in communicating with other people (and other species) in ways we’re
just beginning to understand.”
Hamblin also highlights the bare-faced cheek
behind the rise of the skincare industry, as soap progressed from a
multipurpose, often homemade product to a seemingly infinite parade of
near-identical concoctions advertised for different problems, genders
and occasions, at wildly different prices. Once hooked on daily soapings
that remove our natural oils, we needed moisturisers and hair
conditioners to replace them. In the 50s, the industry further cashed in
by highlighting the drying effects of soap and offering milder
detergents. Today, Hamblin writes, we have come full circle; many people
seek products that are “as close as possible to nothing at all”.
He writes about a fellow journalist – and soap dodger – Maya Dusenbery, who had been prescribed every acne treatment going. The only one that worked? Nothing at all.
She had tried astringents, to dry out the skin;
oral and topical antibiotics; the pill; and isotretinoin, a drug that
has been linked to side-effects such as suicidal thoughts
and inflammatory bowel disease. Not only were these ineffective, but
she also developed rheumatoid arthritis – an agonising autoimmune
condition. When she started taking immune-suppressing medication for
that, her hair started falling out.
Enough was enough: Dusenbery stopped taking any
medication for her skin. After an extremely oily few months, it settled.
Now, the only things that touch her face are a microfibre cloth and
water. Thanks to her adoption of a more holistic approach to her
rheumatoid arthritis, in consultation with a specialist, this has gone
into remission, too.
On the subject of antibiotics, Hamblin writes
that they have commonly been prescribed for acne; he says they “seem to
play a part in causing and exacerbating autoimmune disease” and that
“antibiotic overuse is likely to be a bigger threat to biomes than
hygiene”.
Perhaps as a result of experiences such as
Dusenbery’s, microbiologists, dermatologists and skincare companies are
striving to create new medicines for skin conditions, along with
mainstream beauty products that contain live bacteria or ingredients
that could feed our microbiomes. There is even the prospect of bespoke products
from beauty behemoths such as L’OrĂ©al that are tailored to our own skin
microbiomes, which are as unique as our fingerprints. But we are
certainly not there yet – and we should be wary, says Hamblin, of
“anyone who’s out there right now selling a single microbe, or who tells
you that you have a certain [microbial] imbalance you need to get
corrected medically”.
There is a good chance we will never understand
our microbiomes well enough to manipulate them confidently and to
positive effect. “Maybe there are some things we can do, but … it keeps
coming back to this holistic sense of ‘everything matters’.”
Microbiologists have found that hunter-gatherers
and Amish people, who work together on farms from childhood, have
optimally diverse microbiomes and minimal chances of contracting
autoimmune conditions and associated inflammation.
Urban westerners who want to boost their more modest skin microbes would
benefit from close contact with other people and animals, and from
spending as much time as possible in nature, preferably getting dirty.
But now that we are in a pandemic, much of that
behaviour is on hold. In fact, if the relative sterility of the world
before Covid-19 (in which Hamblin’s book was written) was already
compromising our microbial balance, lockdowns and social distancing
could challenge it even more. “I don’t know when we’ll go back to
handshaking and ways that we might have been sharing different sorts of
microbes with one another,” says Hamblin.
Of course, reducing antibiotic use is key to
microbiome success, along with resisting washing so frequently. Which
brings us to bottoms – for this is what people visualise when they get
grossed out over other people not soaping themselves. How can you get
rid of unwanted residue down there with just your hand and water? “Dry
toilet paper kind of creates that problem,” says Hamblin. “If you were
gardening and had mud all over your hands, would you just use a dry
paper towel? No, you’d at least get them wet and scrub them together.
When people use bidets, they have less of an issue with that, or when
people use disposable towelette things.” But the towelettes are
expensive, wasteful and block drains, he admits, so “wetting toilet
paper is fine”. This is his solution, which he shares to satisfy
curiosity, rather than to preach or prescribe. And no, the paper does
not fall apart when wet – “unless you’re trying to drown it”.
