Do you like the smell of flowers? Let’s learn five natural nose facts for kids.

Nose Facts for Kids Fact Number 1: Your Nose Hairs Help Your Immune System

The human nose is the best air filter in the world all because of the mucus and hairs contained in the nose. When you breathe in air the air passes through hairs which are covered in mucus. The air we breathe contains pollen, bacteria, germs, and dust which can irritate our lungs and cause disease. Our noses protect us from all of this by filtering all these things through nose hairs. So, the hairier the nose the healthier you will be.

Nose Facts for Kids Fact Number 2: Your Nose Changes The Humidity of The Air You Breathe

Humidity is the amount of water which is contained in the air. Some places in the world, like rain forests, have very high humidity as they are warm and wet. The air we breathe in may be very dry or cold, which is uncomfortable for our lungs. When we breathe in through our nose, the air gains humidity which makes the air easier to breathe into our lungs. The nose also makes the air warmer if it is too cold, so the lung does not get too cold.

Nose Facts for Kids Fact Number 3: The Human Nose Can Detect over 1 Trillion Smells

There are smells everywhere in the world including the grass we walk on, the food we eat, and even the air we breathe. Our nose doesn’t actually do the smelling but it does detect the particles in the air which create smell. Our brain takes in the information collected by the nose and understands what the smell is. The brain stores these memories which is why we have favourite smells the brain remembers. There are over 1 trillion smells that the human nose can detect and we don’t even have the strongest noses in the world. Dogs are a species that can smell trillions more smells than we can.

Nose Facts for Kids Fact Number 4: Smells Can Help You Relive Positive Memories

Your nose is connected to the memory centre of your brain, which is where all your long term memories are stored. When you smell something it may remind you of a specific memory and help you relive that time in your life. A great example of this is foods which are made at family events. Does your family have special recipes which you have at celebrations like birthdays or holidays? When you smell these foods your brain remembers them and you might start thinking about happy memories.

Nose Facts for Kids Fact Number 5: Your Sense of Smell Affects How Things Taste

This is because over 75% of what we taste is actually related to our sense of smell, if something smells bad we are more likely to believe it tastes bad. This means that if you have to eat or drink something that doesn’t taste very nice you can lessen how bad it tastes by holding your nose. If you can’t smell it, it will taste less bad.
