Several studies point to the positive effects that low-power light treatment can have on the healing process of wounds. However, the employment of LEDs as a kind of therapeutic intervention is still a contentious topic. There are questions over whether or not the impacts that are generated on biological systems by LED and LASER are comparable to one another. This experiment had several objectives, one of which was to determine the biological effects that offer support to the employment of LED on heart rate and blood pressure. Changes in the light intensity of different colors can produce shifts in a broad number of physiological states and indices. Some of these states and indices include melatonin, alertness, body temperature, heart rate (HR), and heart rate variability (HRV). Following exposure to red light, the purpose of this pilot research was to explore any sudden changes that occurred in HR as well as blood pressure
