Red Light Therapy Shows Promise in Protecting Football Players’ Brains

A small , new study suggests red light therapy may help protect athletes from brain damage caused by repeated hits.

Researchers followed 26 college football players over a full season.

Half used a red light device — a headset with a small nasal clip — that delivered infrared light through the skull three times a week for 20 minutes per session. The rest used a placebo.

MRI scans taken before and after the season showed a clear difference.
