While blue light therapy has similar mechanisms for skin enhancement as red light therapy, its usage for photodynamic therapies in treating cancer are slightly different. Blue light therapy stimulates immune system defences, destroys blood vessels that help cancer cells grow, and causes cell death by reacting with oxygen. [ 16 ]
Photopharmacology is an emerging multidisciplinary field that combines photochemistry and pharmacology. [1] Built upon the ability of light to change the pharmacokinetics and pharmacodynamics of bioactive molecules, it aims at regulating the activity of drugs in vivo by using light. [2]
An example system can consist of a light source (generally a laser or a lamp), a controller for the amount of light that enters, a guide for the light, and a delivery system. Often, the design function in such a way that a medium is met between the diffusing light that may cause additional, unwanted photolysis and light attenuation; both being ...
Light therapy, also called phototherapy or bright light therapy is the exposure to direct sunlight or artificial light at controlled wavelengths in order to treat a variety of medical disorders, including seasonal affective disorder (SAD), circadian rhythm sleep-wake disorders, cancers, neonatal jaundice, and skin wound infections.
Photomedicine is an interdisciplinary branch of medicine that involves the study and application of light with respect to health and disease. [1] [2] Photomedicine may be related to the practice of various fields of medicine including dermatology, surgery, interventional radiology, optical diagnostics, cardiology, circadian rhythm sleep disorders and oncology.
[3] [4] However LLLT has been marketed and researched under a number of other terms, including red light therapy, [39] low-power laser therapy (LPLT), soft laser therapy, low-intensity laser therapy, low-energy laser therapy, cold laser therapy, bio-stimulation laser therapy, photo-biotherapy, therapeutic laser, and monochromatic infrared light ...
Bright light therapy, widely understood to be an effective treatment for Seasonal Affective Disorder (SAD), can also be helpful in treating other types of depression, finds a new meta-analysis ...
Photodynamic therapy is also used to relieve symptoms of some cancers, including esophageal cancer when it blocks the throat and non-small cell lung cancer when it blocks the airways. [ 26 ] When cells that have absorbed photosensitizers are exposed to a specific wavelength of light, the photosensitizer produces a form of oxygen, called an ...
