When choosing a perfume, can you smell coffee beans to restore the sense of smell?

Smelling coffee beans when buying perfume is to let the smell of coffee beans transfer the excitement of the nerve center for the smell of perfume, and turn the excitement to another point.

Smell is a sense that involves two sensory systems, the olfactory nervous system and the nasal trigeminal nervous system. The sense of smell is a telesense, that is, it is the sense of feeling a chemical stimulus over a long distance.

The sense of smell is caused by particles in the air acting on the sensory cells in the nose. There is an olfactory epithelium in the nasal passages, and the olfactory cells in the epithelium are the peripheral receptors of the olfactory organs.

In vertebrates, olfactory receptors are usually located in the olfactory epithelium, which consists of supporting cells, olfactory cells and base cells in the nasal cavity. In the olfactory epithelium, the axons of olfactory cells form olfactory nerves. The olfactory tract is bulbous and bulbous, located below the frontal lobe of each cerebral hemisphere. The olfactory nerve enters the olfactory bulb. The olfactory bulb and telencephalon are the olfactory centers.

Therefore, the production of smell is caused by the olfactory receptors located at the top of the nasal cavity, that is, the olfactory cells on the olfactory mucosa are stimulated by some volatile substances, which will produce nerve impulses, and the impulses are transmitted to the cerebral cortex along the olfactory nerve and cause smell. Their position is not a passageway for breathing air, but a shield for the bulge of the turbinate, so that odorous air can only reach the olfactory receptors in a circular flow.

The human nose can smell up to three smells at a time, and untrained people can smell up to seven in extreme cases. In the selection of perfume, due to repeated stimulation and olfactory fatigue, so will not smell the fragrance. Studies have shown that there are 27 influential odor molecules in ground seed coffee, and smelling so many smells is not enough to clear the nose; Smelling coffee beans when buying perfume is to transfer the smell of coffee beans to the nerve center's excitement for the smell of perfume and turn to another point of excitement. So if you need to adjust your sense of smell, the more common and simple way is to smell the skin of your arm, the most common part is the inside of your elbow. This is because this area is equivalent to the taste of its own skin, which can largely eliminate the sense of smell. In addition, there are also practices to smell silk handkerchiefs, the reason is that in various substances, silk and cashmere are neutral and odorless substances, which can effectively filter the odor.

Therefore, the olfactory paralysis caused by perfume selection can not only be relieved by coffee beans, but also can be transferred to the olfactory central stimulation by other relatively non-irritating odors, so as to restore the olfactory paralysis state.
