The non -invasive technique that improves the meaning of smell

A team of researchers from the Hanyang University and the Kwangwoon University (South Korea) have discovered that a brief radio wave therapy It can improve the sense of smell in a “simple and painless” way, and without the need for surgery or use chemicals.

“The method is completely Non -invasive (It does not need surgery or chemical products) and safe, since it does not overheat the skin or cause discomfort, “said the author of the article, Yonwoong Jang.

During the investigation, published in the magazine App bioengineering, Volunteers were asked with good smell to undergo soft radio waves For five minutes to reach olfactory nerves in the depths of the brain.

The scientists checked both the patient’s ability to perceive very faint odors, such as diluted alcohol or fruit aromas, using swallow -shaped smell dispensers called ‘sniffin sticks’.

In addition, they registered patient brain signals to observe the activity of their olfactory nerves, What has given rise to the finding that this method improves the meaning of the smell of the subjects for more than a week after a single treatment.

“This study represents the first time the meaning of a person’s smell is improved using radio waves Without any physical contact or chemical productsand the first attempt to explore radiofrequency stimulation as a possible therapy for neurological conditions, “said Jang.

The results of the current study, focused on people with a sense of normal smell, could help professionals such as perfumers, chefs or coffee tastors to distinguish aromatic subtleties.

The method could also serve to preserve or enhance the meaning of smell, so the next step of the research team is to carry out a similar study in individuals with olfative dysfunction, such as anosmia or hyposmia.

The new research line will help them determine whether the treatment “You can really benefit” to those who need it most, and that is that many people, especially After the Covid-19 pandemic, Aging or a brain injury have suffered loss of smell.

Despite this, they currently exist “Very few effective treatments” To reverse this situation, and those that exist often use strong aromas or medications that cause discomfort to patients.

Faced with the patient’s exposure to chemical substances, this radio wave method can act directly on the part of the brain responsible for smell and without causing pain.
