After reaching the age of adolescence, human body undergo to many changes and people start to sweat a lot and the sweat smells really bad. Studies have showed that more than 90% of teenagers and adults in the US use antiperspirant or deodorant to neutralize the bad odor caused by the sweat.

However, scientists explain that even 78% of the people should not use deodorant and the reason for that are their genes.

It is generally accepted that people smell because they sweat a lot, but that actually is not true. It is important to understand that the sweat does not smell, but the bacteria in the armpits releases the awful smell. The sweat contains lipids and amino acids which are easily broken down by the bacteria and then they transform into substances that has a different smell. The result of this is our body odor.


Over the last decades, the hygiene routines are significantly changed and along with that, the methods for solving the problem with body odor are changed, as well.

Namely, there are two methods for fighting the smelly armpits: the first method is elimination of bacteria by using deodorants that contain triclosan and the other method is blocking the sweat glands and killing the bacterium that causes the bad smell by using deodorants that contain aluminum.

Scientists studied human body and concluded that deodorants that contain such chemicals have great impact to the health and use of these products can lead to various health issues, including life threatening Clostridium Difficile Colitis (C. diff).

The armpit has various naturally placed bacteria and this body area is the most heavily populated by bacteria. However, it is important to mention that the microbial community does not diverge. Dr. Armpit explains that people have five times more diversity on the hand or two times more on the belly button.

About 70% of the bacteria in the armpit area belong into one of the two groups: odor related group and second group that is not related to bacteria.

The bacteria in the gut can be destabilized by some antibiotics or some food, and in such case the good bacteria is eliminated and the microbes start causing problems. On the quite similar way, this problem can appear in the armpit, as well.

In order to stay healthy, any ecosystem needs to be balanced. Therefore, by avoiding the products that can damage the ecosystem, you will decrease the amount of bacteria that causes the bad smell and over certain period of time, you will manage to eliminate them completely.

It’s Not Just About Body Odor

Microbiome research has revealed that entire human body is linked to the microbe community. It is interesting to mention that scientists discovered that, besides the gut microbiome has an effect on the digestion, they also have influence on the person’s attention and mood. Namely, the connection between our body and the ecosystem is showed through the underarm area.

Therefore, instead of working against the microbiome and trying to destroy them, we should work with them. Our advice is to start with these simple tricks:

Use Mild Soaps: soaps that contain strong surfactants such as SLS, SDS or castille soap, eliminate the protective sebum that is loaded with good fats which are responsible for protection of our skin. Instead, you should use mild soaps that create perfect environment for developing of good microbes.

No Aluminum: aluminum is an active ingredient that has the ability to restrict the process of sweating. There are many scientific studies which have linked the aluminum with many diseases and health conditions.

On the market you can find many products with the label “aluminum ­free” because the companies are trying to highlight the fact that the formula of their product does not contain this detrimental ingredient.

Avoid Crystal Deodorants: next time before you buy a deodorant, first check the label. Very often the producers claim that the deodorant is aluminum free, but there is a trick, so you should be careful. The ingredient called “alum” is a part of the harmful potassium aluminum sulfate. Even though this option is safer than other antiperspirants, you still should avoid it.

Be Cautious When Using Strong Antibacterials: parabens and triclosan are strong antibacterials that often are contained in these products. It is important to highlight that the strong antibacterials destabilize the microbiome and prevent the development of the good bacteria on the armpits.
