Definition and causes of body odor
Body odor is a perceived unpleasant smell our bodies can give off when bacteria that live on the skin break down sweat into acids - some say it is the smell of bacteria growing on the body, but it really is the result of bacteria breaking down protein into certain acids. the body. These bacteria multiply rapidly in the presence of sweat. Sweat is actually odorless; it is bacteria that live off perspiration on our body that create the bad smell.
Types of acid contain in the body odor .
Propionic acid and Isovaleric acid is found in the sweat. These two types of acid are commonly present when there is body odor. Also , there are two types of sweat glands : Eccrine glands and Apocrine glands.Humans generate apocrine and eccrine sweat. Eccrine sweat is used to lower our temperature, like when we exercise or when it's really hot. It is produced uniformly all over the body and does not smell.
Apocrine is a special type of exudation that is produced in places like the armpits, groin, hands, and feet. It is the latter that causes all the trouble, but like eccrine sweat, it also doesn't smell. Apocrine perspiration simply contains fat and protein.
How does apocrine sweat tend to make us stinky?
Some bacteria on our body feed off apocrine sweat. Once they consume the sweat, they do what any living creature on earth does: they defecate . B.O. is the smell of bacteria excrement!
Actually, bacteria don't really defecate like we do -- they break down chemical bonds -- but they do consume our perspiration, and that makes us smell.
Causes of body odor also due to inadequate bathing (and/or cleaning/washing of clothes). It is caused by skin bacterial activity on sweat which has dried on the skin - and this makes people who sweat excessively more likely to be affected. In some people (the excitable 'greyhound/racehorse' types) the sympathetic aspect of the nervous system is dominant and they tend to sweat more, whereas in others (the calmer 'bulldog/carthorse' type) the parasympathetic aspect dominates and they tend to stay calmer. So keeping stress levels low is important for people who sweat a lot.
Antiperspirant vs Deodorant:
The variation most commonly used in deodorants and antiperspirants is Al2Cl(OH)5. Aluminium chlorohydrate is one of the most popular active ingredients in commercial Antiperspirants.
Types of Antiperspirant Deodorant
Deodorant – kills bacterial through a number of ways. It may be a spray or aerosol product that contains alcohol that will temporarily kill bacteria. It might be a roll on or gel that contains an antimicrobial metallic compound. There are roll on deodorants made with naturally anti-microbial hops.It doesn't prevent you from sweating, but prevents bacteria from thriving on body parts where you sweat. A chemical called triclosan makes the underarm skin too acidic and that prevents your armpit from becoming a home to the bacteria, thus, reducing chances of bad odor.
Antiperspirant – uses various forms of aluminum to block the production of sweat. Aluminum reacts with compounds on the surface of your skin to form a kind of plug that blocks your pores.Antiperspirants differ from deodorants in that they don’t just mask the odor, but actually block the skin pores so that moisture isn’t released. The active ingredient that does this is an aluminum based compound that blocks the pores by forming a gel-like plug. Not only does this gel-like plug reduce odor, but it also keeps your underarms dry so you won’t stain your best white shirt.it usually has a fragrance to make the user smell good. The association between exposure to aluminum and long term use of antiperspirants and Alzheimer's disease is a trend toward a higher risk with increasing frequency of use.
Deodorants or antiperspirants: Which is best?While it may seem as if an antiperspirant would be the obvious choice since it has the dual function of reducing odor as well as keeping you drier, antiperspirants have been the subject of some health scrutiny. Aluminum compounds, like those found in antiperspirants, have demonstrated harmful effects in animals and are thought to be toxic to nerves and, possibly, to the kidneys.
However ,aluminum compounds used in the antiperspirants can get assimilated in the blood stream and cause serious health issues.
While deodorant can mask the odor temporarily, it cannot stop a person from sweating the way an antiperspirant does. Once the sweat combines with odor causing bacteria, the underarms will begin to smell again.
Deodorants and antiperspirants are used to stop the smell of body odor that is created by a combination of bacteria and sweat.Deodorants attack odor causing bacteria to eliminate smells whereas antiperspirants prevent your body from sweating and therefore keeps you both dry and smell-free.To compare which is the safer to use ,the answer will be Deodorants .Deodorants are considered to be safer than antiperspirants because they don’t stop the body’s natural method for cooling down.
