Igusa is known for its unique scent that is said to have health benefits, but such claims lacked scientific evidence. Professor Kuniyoshi Shimizu from Kyushu University and his research team used EEG to monitor the brainwaves of participants while they sat on Igusa mats and completed a series of tasks. They found that when participants used Igusa mats, their brain activity showed patterns associated with increased concentration and engagement.
