In this study, low level light therapy (LLLT) was applied to the forearm of 15 subjects. Before and subsequent to this procedure, blood levels were regularly measured for levels of nitric oxide. The results demonstrated that LLLT increased NO levels in venous blood draining from the treatment site, and this phenomenon peaked after 5 minutes of light therapy <view study> Read Less

Researchers at the University of Texas at Austin, published a study in the Journal of Neuroscience, stating that this was the first demonstrated study showing the beneficial effects of transcranial light stimulation on cognitive and emotional functions in humans. With particular focus on the frontal cortex of the brain, they looked at neuropsychological tests on attention, memory and mood, following transcranial light therapy. The results of the study showed that ALL 3 parameters measured were significantly improved. This lead them to conclude that "Transcranial infrared laser stimulation has also been proven to be safe and successful at improving neurological outcome in humans in controlled clinical trials of stroke. This innovative approach could lead to the development of non-invasive, performance-enhancing interventions in healthy humans and in those in need of neuropsychological rehabilitation" <view study> Read Less

Researchers at George Washington University in Washington DC, assessed 86 participants who went through a course of 2 weeks of light therapy over the waist, hips, and thighs, for 20 minutes front and 20 minutes back. This procedure was done every other day for the 2 weeks and EACH person reported a statistically significant reduction with the mean loss being around 3 inches, over the 2 week duration <view study>   Read Less

The University of Florida ( Department of Applied Physiology and Kinesiology) has just published a study in the journal of athletic training, demonstrating the effectiveness of low level light therapy on athletic performance. The looked at 12 randomized controlled trials and the data showed that if this light procedure was applied immediately before exercise, then there were many benefits that were noticed. Among these benefits included, a reduction of fatigue which positively affected physical performance, and post-exercise recovery <view study> Read Less

Transcranial light therapy is becoming more popular for treating patients who have had a stroke or traumatic brain injury. This study was able to reproduce significant improvements and attributed this to light's ability to possibly aid in neurogenesis or the development for new brain cells <view study> Read Less
