Snot, boogers, bogeys, mucus, phlegm are all words used to describe the excretions from your nose. It usually causes giggles when talking about it but it actually has a very important job.
Here are 6 facts you may not know about snot.
1) The scientific word for boogers and snot is mucus.
2) Mucus is a wet, sticky, thick, slimy substance that coats the inside of your nose and nasal passages. With every breath you take, you inhale germs, pollen, dust, dirt, sand, and even old skin cells. If not for mucus, all these things would travel on their merry way to your lungs.
3) When you have a cold virus, your body defends itself by making lots of snot, it’s your body’s way of trying to flush the virus out. After a few days your boogers may become white or yellow– that’s your immune system creating cells to fight back, this is a good thing.
4) Snot’s purpose is to keep the lining of the nose moist. The drier the lining, the more prone you are to infection. Snot and phlegm are full with all sorts of potent antiviral, antibacterial, and other protective chemicals that work to keep you healthy.
5) Your nose and sinuses make a litre of mucus a day.
6) Snot helps you with your ability to smell. In the mucus membranes, which produce snot, there are things called smell receptors which deliver information to a nerve called the olfactory nerve. The information delivered by the receptors tells your brain what you smell by selecting a percentage of one of seven different “smell sensations”.
