In a world where sense of sight is primarily used, this diffuser tray stimulates both a sense of smell and touch simultaneously. Rotating the aroma diffuser with your hands allows the fragrance to spread across the entire desk. These simple and repetitive motions improve tactile sensory while also relieving tension and stress. Since a sense of smell is directly linked to the brain’s limbic system, fragrance can affect our mood and emotions. NIWA can give you a relaxing experience that distracts you from your hectic daily work environment.
