The quality of sleep is directly linked to the quality of human life. Irradiation of blood in the transcutaneous vascular technique is believed to decrease blood viscosity and platelet aggregation; activates superoxide dismutase; promotes increased oxygen content and stimulates microcirculation, it also stimulates increased serotonin production and cortisol reduction. Serotonin functions include sleep initiation, mood improvement, anxiety and depression. Therefore, the objective of the present project is to evaluate the effect of ILIB on salivary biomarkers related to stress and sleep. Therefore, participants with problems related to sleep quality will be selected and divided into 2 groups, group 1 undergoing ILIB Therapy twice a week for 30 minutes and group 2 the same frequency and time of application, but with placebo equipment. At the end of 10 sessions, salivary biomarkers related to stress and sleep and the patients' perception will be evaluated through specific questionnaires on the effect of ILIB on sleep, stress and relaxation.
Randomized clinical trial to evaluate the effect of vascular photobiomodulation on sleep quality, relaxation and stress when compared to placebo.
