Stress-Related Effects of Low-Intensity Laser Irradiation

Abstract

The purpose of this study was to investigate the effect of low-level laser (light) therapy (LLLT) on the electrokinetic properties of red blood cells (RBCs), taking into account the activity of stress-realizing systems of the body. The RBC electrophoretic mobility (RBCEM) was used as an index of stress reaction. The experiment included two series: in vivo and in vitro. Analyzing the LLLT effect on RBCEM, we can assume that the body's response to LLLT is associated with a short-term activation of the sympathoadrenal system and the subsequent longer reaction of the hypothalamic-pituitary-adrenal axis. Through activation of the hypothalamic-pituitary-adrenal axis, LLLT can indirectly cause the development of adaptation processes in the body.
