Igusa Mats Linked to Better Focus and Lower Anxiety

Researchers at Kyushu University have published a study in *Scientific Reports* demonstrating that mats made from Japanese Igusa, a type of rush grass, can enhance brain activity associated with concentration and engagement. Using functional magnetic resonance imaging, the team observed increased activation in cortical regions linked to focus when participants lay on Igusa mats compared to control surfaces. The findings suggest that the material’s unique texture and compressive properties may stimulate neural pathways involved in sustained attention.

In addition to neuroimaging data, the study included a survey of participants who reported lower levels of tension and anxiety after using the Igusa mats. The researchers noted that Igusa has been employed in Japanese culture for centuries in items such as bedding and floor coverings, yet its physiological effects had not been scientifically documented. By providing empirical evidence of its calming benefits, the team hopes to elevate the material’s value and encourage broader adoption in wellness and ergonomic products.

The study’s authors emphasize that further research is needed to confirm long‑term benefits and to explore optimal usage conditions. Nevertheless, the results offer a promising intersection of traditional materials and modern neuroscience, potentially informing future designs of therapeutic and office environments that promote mental well‑being.
