Kyushu University study links Igusa mats to improved focus and lower anxiety

Researchers at Kyushu University have discovered that traditional Japanese Igusa mats, also known as rush grass, may provide mental health benefits. According to a study published in the journal Scientific Reports, using these mats is associated with increased activity in brain regions linked to concentration and engagement.

In addition to cognitive benefits, participants in the study reported reduced levels of tension and anxiety after using the mats. The research team, led by Associate Professor Kuniyoshi Shimizu, utilized objective scientific methods, including electroencephalograph (EEG) measurements and psychological questionnaires, to compare Igusa mats against unscented polypropylene plastic mats.

While the scent of Igusa has been culturally associated with relaxation and comfort in Japan for centuries, this study aims to provide scientific evidence to support those claims and add new value to the traditional material.
