light-guided brainwave shifts toward alpha and theta states improve working memory by ~22%
Chromotherapy light stimulations adapted to real-time EEG dominant brain wave frequencies guided participants' brain activity toward theta (4–7 Hz) and alpha (8–13 Hz) states, producing measurable improvements in visuospatial working memory (Corsi block-tapping task total score increased by 22.4%) in long COVID patients.
What this means for you
Alpha and theta brainwave states are linked to calm focus, mental clarity, and the ability to hold and process information. When light stimulation nudges your brain toward these frequencies, it may support sharper short-term memory and cognitive resilience — something many people notice as feeling more mentally present and less foggy.
