Scientists Identify 7 Smells That Improve Memory and Cognitive Processes in the Brain

Each of the five senses is very valuable and serves an important function in the body.

Some of them become more important as we get older: THE adult adults They can use their senses to orient themselves in time and space, as well as to recover memories if they begin to suffer from neurodegenerative diseases, such as dementia and the Alzheimer’s .

For himhe smell This is one of the key meanings since a recent study from the University of California-Irvine found that the smells of different things, like flowers or food, can transport us back in time, revive forgotten memories, and improve the brain’s cognitive ability.

For six months, two hours every night, a scent wafted through the rooms of a group of elderly people. : The results were surprising, as his memory skyrocketed.

Participants increased their cognitive ability by 226%.

This discovery transforms the link between smell and memory, according to the researchers, and makes aromatherapy a simple, non-invasive technique to strengthen memory and thus have more tools in the fight against neurodegenerative diseases, such as dementia.

Each night, Participants, men and women aged 60 to 85 and without memory problems, used an essential oil diffuser, which was activated for two hours while they slept.

The odors used during the investigation were:

1. Pink
2. Orange
3. Eucalyptus
4. Lemon
5. mint
6. Rosemary
7. Lavender

After taking images, it was found that the use of aromas allowed for greater integrity of the brain pathway that connects to the area where decisions are made, among other functions.

Furthermore, Older people reported being able to sleep more soundly, which is essential for preventing various diseases.

“The sense of smell has the special privilege of being directly connected to the brain’s memory circuits.” said professor of neurobiology of learning and memory and study researcher Michael Yassa.
