We’ve all heard about the benefits of LED lighting.  It’s extremely energy efficient, long-lasting and cool to the touch as long as the fixture is well-designed.

Well, here’s an LED benefit we didn’t see coming.  A recent study found that LEDs can play a key role in helping patients recover from traumatic brain injuries (TBI).

In the study, LEDs were used daily as light therapy on TBI patients’ scalps and foreheads.  Doctors reported significant improvements in cognitive function for patients that received the therapy.  In addition, the LED light therapy seemed to reduce the severity of post-traumatic stress disorder.

The study was carried out by researchers at Boston University School of Medicine, Massachusetts General Hospital and Harvard-MIT Division of Health Sciences and Technology.

    I wonder if they would have gotten the same results with a regular light bulb. I guess the best way is to test both light sources at the same time and see if the led helps more.

    Stefan – that’d definitely be interesting to test. I found a more detailed report of the study in case you want to read: http://www.medpagetoday.com/Neurology/HeadTrauma/25433. It’s fascinating!
