Joyful or mirthful laughter produces brain wave frequencies similar to those seen among people who reach what is considered the desired “true state of meditation,” according to a new study from Loma Linda University Health.
“When there is mirthful laughter, it’s as if the brain gets a workout because the gamma wave band (the only frequency found in every part of the brain) is in synch with multiple other areas that are in the same 30-40 hertz frequency. This allows for the subjective feeling states of being able to think more clearly and have more integrative thoughts. This is of great value to individuals who need or want to revisit, reorganize, or rearrange various aspects of their lives or experiences, to make them feel whole or more focused,” said Lee Berk, DrPH, MPH, principal investigator of the study and associate professor School of Allied Health Professions and associate research professor, pathology and human anatomy, School of Medicine, at Loma Linda University.
Subjects who engage in joyful laughter produce substantial brain gamma wave band frequencies (30 to 40 Hz), which, according to other published research, are now known to be similar to those experienced by people who meditate and reach a state of contentment and happiness, the study said.
“Laughter may not only be a good medicine for the health of your body but also a good medicine for your brain,” Berk said.
