THE SCIENCE OF SWEAT & BODY ODOUR
Okay, here’s the thing. That smell you smell when you sweat, isn’t sweat. Sweat itself is basically a clear, odourless liquid mostly made up of water, salt, proteins, and oils.
But mix it with the millions of harmless bacteria that grow in moist, humid and nutrient-rich environments like our armpits, and it can start to smell.
The good news is there’s lots you can do to reduce body odour. So, don’t let it put you off getting your sweat on.
Getting under the skin of body odour
Body odour is the smell our bodies give off when they sweat. And it occurs for various reasons, although it’s essentially down to your sweat glands and the bacteria that live on your skin.
So, let’s talk sweat glands. There are two types…
Eccrine glands
They produce sweat that simply cools your skin when you get too hot.
Built-in air con for your body if you like.
Apocrine glands
These kick in at puberty and produce sweat that creates body odour when it comes into contact with bacteria. Turning your armpits, groin and other areas into breeding grounds for B.O.
SO, BODY ODOUR’S ALL DOWN TO OUR GLANDS?
Unfortunately, it’s not that simple. Changes in diet, hot or humid weather conditions, wearing synthetic clothing and even certain types of medication can all activate that distinctive smell. Speaking of which, ever noticed how body odour smells a bit like vinegar?...
WHAT’S WITH THE VINEGARY SMELL?
Bacteria from the sebaceous glands of the body break down sweat into something called propionic acid, which comes from the same family as common vinegar. Hence that vinegary body odour when you’ve been sweating, whether from a gruelling HIIT class, nerves about a job interview or first date jitters.
SAY NO TO B.O.
Having smelly armpits may be natural – but that doesn’t mean you want them. So, here are some tips on beating B.O.
Hit the shower at least once a day
And use antibacterial soap to wash yourself thoroughly.
Keep it short and sweet (your body hair, that is)
Hair hangs on to sweat, so keeping hairy areas trimmed helps keepB.O. at bay.
Wear clothes that breathe
And avoid synthetic fibres that trap sweat on your skin.
Use an effective antiperspirant deodorant
Like Rexona Women Clinical Protection Summer Strength or Rexona Men Advanced Protection Sport.
Avoid odour-causing food
Taking garlic, onion, curry, cumin, fatty foods and red meat off the menu could make a difference.
