Inhalation improves brain performance, new study finds

Researchers have recently discovered that inhalation can significantly improve brain performance.

A team from the Weizmann Institute of Science (WIS) in Israel discovered the findings after investigating the link between the two. The results showed a positive success rate for those who were able to solve questions during inhalation.

The sense of smell is thought to be an initial pattern for brain development because it is the earliest sense for mammals. Researchers believe that inhalation works to make the entire brain process information.

For the study, the air flow in the noses of participants was measured. The team did this process while the group performed visual-spatial tasks, languages tasks, as well as during solving math exercises.

When they were done with one task, participants had to press a button to signal they were ready for the next. Researchers found the individuals had to put in the air into their bodies in order to get ready to attempt the next task. While performing the visual-spatial task, some questions had to be answered during inhalation and the rest during exhalation. The results showed inhalation improved participants' success rates when responding to a question.

By measuring electrical activity in each person's brain when they rested and performed tasks, the team found that the connectivity between the brain areas was different during the process of inhalation and exhalation.

The findings could potentially lead to the development of better learning methods for people, particularly those who suffer from attention deficit hyperactivity disorder (ADHD).

However, researchers noted that oxygen entering the body was not the reason why the results reflected what they did. Further research is needed to understand how the process really works.

The study was originally published in the journal Nature Human Behavior.
