facts about sweat

Sweat is a natural body function, and most of us take it for granted. You get hot or go for a run, and the sweat starts to pour. But did you know that sweat can do more than cool off your body? It can come out a surprisingly different color and it slows down the older you get. These are just a few of the interesting facts about sweat we’ve gathered. In this article, you can quench your thirst for trivia and discover all sorts of fascinating facts about sweat.

What is the purpose of sweat?

The purpose of sweat is to cool down your body. When your body is exposed to too much heat, either internally or externally, it produces sweat to bring your temperature back down. It is your body’s own temperature regulator. Being in hot weather, exercising, and eating spicy foods are just some of the factors that cause your body to sweat to balance out your temperature.

Interesting Facts about Sweat

1. Sweat is normally clear, but sometimes you can actually sweat colors.

Did you know that some people sweat in colors? Like a special effect in a scary movie, there are individuals who actually sweat blood, or colors like black, blue or green. It's an anomaly and typically an indication of an underlying medical condition or reaction to medication. 

2. Your emotions can change the composition of your sweat.

One of the most interesting facts about sweating is that your emotions can affect your sweat. For instance, the smell of sweat while scared and while happy can be noticeably different.

3. Your gender and age determine the volume you sweat.

While men have fewer sweat glands than women, men’s glands produce more sweat. They sweat about two times more than females. Also, the older you get, the less you sweat.

4. Your sweat composition is unique, like your DNA.

While everyone sweats, each person’s sweat is made up of its own fingerprint-like composition and can only be linked to the individual. Sweat is made up of 373 volatile compounds that are mixed differently for each person.

5. Sweat, itself, does not usually stink.

Sweat on its own has no smell. However, when sweat reacts with the bacteria on your skin, it becomes odorous and creates body odor. Some other factors, like an underlying medical condition, can increase or change your body odor.

6. You can produce too much sweat.

Hyperhidrosis (or excessive sweating) is a health condition that impacts 4% to 5% of the population, causing them to sweat as much as four to five times more than the average person.

7. Your sweat benefits you in more than one way.

Other than regulating temperature, sweat has other benefits to your wellbeing. It produces an antibiotic peptide that controls bacteria growth and may even help to fight some infections.

8. Certain foods can make you sweat more.

There are a number of foods that can make you sweat more. Some of those are salty, fatty, processed, spicy and sugary foods. The more your body has to work to digest the food you ingest, the more sweat your body produces.

Facts about Sweat Glands

9. You have a lifetime relationship with your sweat glands.

The sweat glands you are born with are the ones that remain with you for the rest of your life. No new glands are ever produced. 

10. Your sweat glands are not evenly distributed throughout your body.

Of the 2 million to 4 million sweat glands you have, the largest concentrated area is located at the bottom of your feet. Conversely the smallest concentrated area of sweat glands is found on your back.
