It has become fashionable nowadays to squirt a blob of Hand
Sanitizer gel onto our palms, rub them together vigorously and voila we think
our hands are clean and microbe-free!
Hand sanitizers have become so commonplace amongst certain
sections of the society that they are being preferred over the traditional soap
and water wash-routine. Children carry it in their school bags and
professionals in their handbags and backpacks.
Here are 5 reasons you might want to say goodbye to that
Hand sanitizer:
- Antibiotic
Resistance: Most of us are floating in a microbial soup – they are all over
us, inside us, and also part of our genetic code. Most microbes are beneficial
to humans and there is a fine balance that is maintained between the “good” and
“bad” bacteria – it is when this balance is upset that we suffer from a stomach
upset for example and the doctor asks us to take a pill with several million
“good” bacteria in them – Lactobacilli (the same bacteria present in
curd/yoghurt). Many hand sanitizers contain the chemical “Triclosan” which
besides being a chemical that can cause hormonal issues also contributes to
antibiotic resistance. In other words using hand sanitizers may actually lower
our body’s ability to resist or fight microbial challenges – the classical
silver bullet that doesn’t differentiate between the “Good” and the “Bad”.
- Alcohol
poisoning: 90% of hand sanitizers reportedly contain alcohol either in the
form of ethyl alcohol (Ethanol) or isopropyl alcohol or a combination of the
two in concentrations ranging from a low of 60% to a high of 90% (As per the
US-FDA, they don’t work at concentrations lower than that). That would
translate to about a few shots of raw, hard liquor from a few squirts! Children (and some adults) who accidentally ingest the hand sanitizer can suffer from serious
consequences of alcohol poisoning.
- Hormonal
imbalance & Lowered immunity: Triclosan, the active ingredient in some
hand sanitizers (and also toothpastes and mouth washes) can cause hormonal
imbalances according to the US-FDA. Further, Triclosan may actually cause
bacteria to adapt and become more resistant to standard antibiotic therapy.
Studies have also shown that “ultra-clean” environments are actually not that
good for children and that Triclosan in Hand sanitizers can lower immunity and immune response particularly in children. The old habit of children
ingesting a little dirt may actually not be that bad after all!
- Increases
skin’s absorption of BPA: Recent studies have shown that hand sanitizers
increase the skin’s absorption of a dangerous chemical – Bisphenol-A (BPA) –
this chemical is used in making clear plastic packaging for food, clear plastic
bottles, and thermal paper receipts (those little receipts that you get when
you swipe your card, or when you buy a bus ticket). BPA is a known endocrine
toxin that can cause serious harm.
- The fragrance/odor of Hand sanitizers: The fragrance and the icky sweet smell that Hand sanitizers give-off can be quite harmful to those who are allergic to fragrances. If the fragrance is derived from phthalates then it can harm major organs in the body including liver, kidneys, and lungs.
A safer alternative is washing hands with plain, normal soap
(not antibacterial) and water. You can always carry a small soap with you. If
soap is not available then a good mechanical scrubbing of the hands under running water for 20
seconds should suffice – pay special attention to areas that can harbor dirt
and debris – between fingers and under nails.

DeleteHeavy marketing with some lobbies declaring days like hand washing day to further this cause. Gullible,frightened public is easy catch for these companies to make a quick dollar
ReplyDeleteYes. It is all in the marketing.
