How the Nose Works
The nose is an amazing part of the human body that helps us breathe, smell, and stay healthy. As air enters the nostrils, tiny hairs and sticky mucus trap dust, germs, and allergens. The air is then warmed and moistened before reaching the lungs, making breathing more comfortable. Millions of smell receptors allow us to recognize thousands of different scents. Sneezing helps remove unwanted particles, keeping the nose clean. Maintaining good hygiene, staying hydrated, eating nutritious foods, and avoiding pollution help keep the nose healthy. A healthy nose supports better breathing, stronger protection, and an improved sense of smell every day.
