Title: Effect of Vascular Photobiomodulation on Sleep Quality.

The quality of sleep is directly linked to the quality of life of human beings. It is believed that the technique known as Vascular Photobimodulation (FBMV) decreases blood viscosity and platelet aggregation; activates superoxide dismutase; promotes increased oxygen content and stimulates microcirculation, also stimulates increased serotonin production and reduced cortisol. Serotonin function is related to the onset of sleep, mood improvement, anxiety, and depression. Given this, we evaluated the effect of Vascular Photobiomodulation (FBMV) through a clinical trial, in which patients presented complaints of low sleep quality. Same frequency and time of application, but with placebo equipment with light emission without therapeutic power (< 1 mW). At patient admission, both groups fill in questionnaires on sleep quality (PSQI and Epwort) were used and at the end of 6 sessions, the questionnaires were collected again. Through the results of the FBMV group (initial PSQI 10.24 – final PSQI 6.47 / initial ESS 10.44 – final ESS 10.12) it was possible to observe positive effects on sleep quality, sleep latency and control of daytime sleepiness demonstrated through a significant decrease in PSQI scores. Through the data presented on Vascular Photobiomodulation (FBMV) without showing a non-invasive technique that emerges as a therapeutic possibility to contribute to sleep quality, the data are promising mainly in the PSQI scores that relate to the overall sleep quality and are consistent with results of improvement and reduction of scores found in clinical trials of pharmacological or non-pharmacological treatment strategies. Data encourage future investigations, especially about the mechanisms involved, better dosimetry, and time of application.
