Sweating is our body’s mechanism of maintaining optimal temperature. When our internal temperature gets too hot, it sends signals to our brain which in turn activate our sweat glands which then secrete sweat.

When sweat combines with the bacteria living under our arms they produce by-products which then leave your underarms smelling! Diet, stress and increased hair-growth all affect the smell directly and you may have noticed when you cut down on sugars and junk the smell actually gets better!

Numerous studies have identified our sweat to contain toxic elements. Our body has proven that our skin is one of the biggest detox mechanisms for heavy metals. So what happens when we use antiperspirants? Well we actually end up blocking these processes and cause re-uptake of these toxic compounds which your body wants to eliminate.


How do antiperspirants work?

Antiperspirants contain an active ingredient: ALUMINIUM SALTS (found on your bottle as aluminium chloride and aluminium chlorohydrate). These work by blocking your sweat ducts by forming a plug over the ducts on the skin. So although the body is producing sweat it just doesn’t leave the skin. (Ngan, 2005)

For safe measure some anti-bacterials are also added to your antiperspirant coz who wants sweaty and smelly armpits? This is usually found under the ingredient Triclosan.


So what’s the problem?

Well for starters Aluminium is a heavy-metal also classified as a neurotoxin which is able to alter the function of your blood-brain barrier. The Blood brain barrier carefully controls what is allowed into the brain and what isn’t. So when this becomes altered hormones, toxins and nutrients which shouldn’t be given access now all of a sudden have a free ALL-ACCESS PASS.

Triclosan is a powerful antibacterial which obviously not only affects the bad bacteria but also the good bacteria which inhibit our gut and are responsible for healthy immune systems and hormone production.

Let’s not forget parabens and phthalates which directly affect estrogen and androgen/ testosterone production respectively!


It seems like a lot asking for you to give up your antiperspirants. Remember that when you initially give up your body may seem like it is sweating excessively but this is just a feedback mechanism that will regulate with time.

There are alternative natural and environmentally friendly deodorants available on the market like Jozi Organics, EarthSap etc. which ensure that you still smell fresh!
