Why Your Sense of Smell Goes Away When You Have a Cold

The Science Behind the Sniffles

When you have a cold, the virus invades the cells in your nasal passages. These cells produce mucus, which helps to trap and remove the virus. However, the mucus can also block your sense of smell. The olfactory bulb is a small structure located at the back of the nose. It contains the receptors that allow you to smell. When the mucus blocks the olfactory bulb, you can't smell anything. Another reason why your sense of smell goes away when you have a cold is because the virus can damage the olfactory nerve. This nerve sends signals from the olfactory bulb to the brain. If the nerve is damaged, the brain can't receive the signals, and you can't smell anything.

How Long Will Your Sense of Smell Be Gone?

1. Most people's sense of smell will return within a few days or weeks.
2. However, some people may experience a long-term loss of smell.
3. If you have a cold and your sense of smell doesn't return within a few weeks, you should see a doctor.
