We have little control over the things we can smell. However, the nose is highly trainable. An example of someone with an incredible sense of smell is Hellen Keller.
As many people know, Hellen Keller was both deaf and blind, this heightened her other senses unimaginably.
Hellen Keller could tell if someone next to her was a carpenter, an artist, a mason, or a chemist.
Inside our nostrils, there are olfactory neurons that capture odor molecules in the environment and translate them into electrical impulses so that the brain can interpret them.
The place in the brain where odors are received is called the olfactory bulb. The olfactory bulb transfers signal to areas of the brain that perceive odors, access memories, and remind us about people, places, or events that we associate with that smell.
There are a few things you can do to train your nose, and you should start right now.
1. Try smelling different things. Like our muscles when exercising, if we use them a lot, they will develop.
2. Linger in the smells. When smelling something, stay there a while, this will provide further information to your brain.
3. Train a lot. It takes years to become a sommelier or perfumer for example. But practicing can improve your ability. Research from the University of Dresden concluded that an average person can increase the size of their olfactory bulbs by testing four aromas, twice a day, for 30 seconds each.
4. Eat healthily. You may not believe it, but if you don't eat healthily, your sense of smell can suffer. Having a myriad of options of nutrients will give you the best sense of smell.
5. Don't smoke. Smoking ruins your sense of smell, this is no surprise, cigarettes have consistently been proven toxic in many levels.
If you follow these steps and practice, you'll train your sense of smell to the point where you can differentiate and pick odors from the environment.
