Treatment
Mechanism
- The principle of red light therapy can be thought of as like a human version of the way plants photosynthesize. It is thought that certain wavelengths of light can enhance the functioning of mitochondria, which are the organelles in a cell which take in nutrients and break them down to create energy molecules for the cell. By enhancing the cellular respiration, it will improve the fun…
Benefits
- The main benefits of red light therapy are thought to have come from the energy exchange. The responses of cells and tissues to red light therapy, which does not itself produce much heat, can be comparable to the bodys reaction to heat. Certain wavelengths of red light can penetrate beyond the skins surface, where it is absorbed into the cells deeper than other wavelengths of vi…
Function
- Just like the bodys natural response to heat is to dilate blood vessels, it does the same when exposed to red light. This widening of blood vessels reduces resistance to the blood flow, therefore improving the rate at which it can move around the body.
Medical uses
- Red light can also be used in conjunction with blue light to treat acne. While the red light is reducing the visual effects of acne by decreasing swelling and pain, the blue light can kill certain types of spot-causing bacteria such as Propionibacterium acnes. When used together, the two types of light therapy can, therefore, reduce and prevent future breakouts.
Results
- The improved circulation can help with weight loss as it will increase the rate at which waste products are removed from the body. However, it is important to understand that red light therapy alone will not cause to you lose a great amount of weight. For best results, it should be combined with regular exercise and a healthy diet.
Research
- A study by Mitchel et al. in 2011 found that red light therapy using near-infrared light for the treatment of restless leg syndrome (RLS) saw significant improvements in symptoms. Out of a total of 34 volunteers, the study group has much greater improvement that the control group did, with results still significantly improved 4 weeks after the treatment period ended. This was a val…
Effects
- Red light therapy uses visible light in the form of lasers or LED. It cannot affect DNA so cannot cause cells to mutate or cause cancer. Red light therapy is generally tolerated very well, although results will vary between people and some conditions will respond better than others.
Side effects
- It is thought that red light therapy has virtually no side effects and those which may occur will be mild and will not last long. For example, eye strain or a headache may be caused by the glare of the intense light. Take care not to stare directly into the light to prevent this and wear suitable eye protection. Some red light therapy kits have built-in eye protection.
Risks
- Care should also be taken when considering the dose being given. Lower doses can be more effective than higher doses. Some effects such as mild nausea or dizziness and muscle weakness may be attributed to overuse, so care should be taken when considering how long a light therapy session will last. Overuse, particularly by infra-red sources, can cause burns so car…
Prevention
- The skin may be more sensitive to sunlight after red light therapy, so take care to always wear adequate sun protection.
Symptoms
- In some cases, for example, using red light therapy for pain relief, effects can be noticed as soon as 20 minutes after a treatment session. In comparison, wound healing enhancement may be fist noticeable after 24 hours.
Uses
- With the introduction of LEDs by those studying the techniques, the term was changed to low-level light therapy or photobiomodulation. The methods have been promoted for the alternative treatment of carpal tunnel syndrome, fibromyalgia, osteoarthritis and even smoking cessation among many others.
