Is there any evidence for red light therapy?

Although there is early research into RLT, there is still no conclusive evidence that it is a beneficial treatment. Many studies show that treatment is promising, but more extensive clinical studies in humans will help determine possible applications of RLT. red light therapy appears to be safe and not associated with any side effects, at least if used in the short term and as directed. This therapy is non-toxic, non-invasive, and not as harsh as some topical skin treatments.

Unlike ultraviolet (UV) light that causes cancer from the sun or tanning booths, RLT does not use this type of light. Hungarian doctor and professor Endre Mester first used red light therapy in 1967 while studying how cancer cells reacted to exposure to. Today, this treatment is used in medical, dental, spa and home settings to help repair tissue and relieve pain and inflammation. Red light can send light particles to the brain that stimulate mitochondria there.

This can promote blood flow and help reduce inflammation in the brain. It can also help the brain create new nerve cells. Does Red Light Therapy Really Work? Yes, red light therapy is an effective health modality that has been extensively studied and tested. With so many therapy options, it's normal to ask yourself “What is red light therapy? “How does red light therapy work? and What does red light therapy do? Watch this video to learn more about the science behind red light therapy and how a red light therapy treatment affects the body at the cellular level.

While “Staying Under This Light for a While” covers the basics, red light therapy is (thankfully) more complex. Patients often undergo several treatments during which they are exposed to low-level lighting. Light waves are said to stimulate the production of collagen, an important protein found throughout the body. The los angeles times also reports that, under the right conditions, red light therapy can reduce inflammation, potentially allowing tissues to heal faster than they would in the absence of treatment.

So why is red light more therapeutic than other types of light? It's not, at least, not as a rule. Some light therapies also use blue lights or full spectrum lights, but different wavelengths of light have different effects. For example, blue light is more effective than red light in controlling symptoms of seasonal affective disorder (SAD), while red light seems more effective for certain cosmetic skin treatments. The main difference is the wavelength and intensity of the light.

Red light has a longer wavelength than blue light, allowing it to penetrate deeper into tissues. Their waves also have a lower frequency, which may make them more suitable for promoting pain reduction. No matter what type of traffic light you're treated with, exact wavelength matters; you can't just sit under a red light for half an hour and wait for results (except maybe a traffic ticket). Experts say it's too early to know if these devices are effective.

Some small studies have shown promise for certain conditions, says Dr. Elizabeth Buzney, Assistant Professor of Dermatology at Harvard Medical School. “I think it's a very exciting emerging area,” he says. But the evidence isn't there yet.

For many years, scientists have studied how the sun's rays affect the skin. First, they focused their attention on the so-called burning rays of the sun, or ultraviolet B radiation, more commonly known as UVB. Then, the focus changed to ultraviolet A or UVA rays. It's the sun's rays that age the skin, causing wrinkles and discoloration.

We have recently started talking about the effects of visible light on the skin, not necessarily LED light, but visible light in general, says Dr. Researchers now aim to better understand how visible light and LED light affect skin. Red and blue lights are often promoted in LED skin treatments. Experts believe that red LED light acts on skin cells known as fibroblasts, which play a role in the production of collagen, a protein that makes up a large part of connective tissue and helps the skin recover when damaged.

So, in theory, red light could help reverse some of the signs related to photoaging in the skin, says Dr. In addition, some studies show that red light can help restore hair for people with androgenetic alopecia or male and female pattern hair loss, he says. For the most part, these LED light therapies appear to be relatively safe, at least in the short term, says Dr. FDA has approved some products for home use.

LED skin devices don't have a lot of power, so they're unlikely to burn your skin. However, it's important to protect your eyes from light while wearing them, says Dr. One brand, Neutrogena, recalled its light therapy mask for acne in July in response to concerns about the device's potential to damage the eyes in people with underlying eye conditions or who are taking medications that make the eyes more sensitive to light. However, there is still much that is not known about the effects of these devices.

The long-term safety of these phototherapies remains uncertain, says Dr. Marissa Heller, Assistant Professor of Dermatology at Harvard Medical School. So, consider these unknowns when weighing the pros and cons of LED light therapy. Red light has a stimulating effect on metabolism and can actually cause fat cells to shrink, for fast and effective fat loss, and associated weight loss.

But does red light therapy really work? Over the past two decades, thousands of published studies have focused on red light therapy. If you decide to purchase a red light therapy device, be sure to protect your eyes to protect yourself, follow all instructions and take good care of the device. That said, red light therapy could simply reduce inflammation by providing a modest heat source, in which case an electric blanket would serve the same function. Red light stimulates mitochondria (the energy centers of muscle cells) to produce more energy, leading to faster cell regeneration and growth.

Red Light Therapy (RLT) is a treatment that uses low-wavelength red light to reportedly improve the appearance of skin, such as reducing wrinkles, scars, redness, and acne. Instead of the messy jumble of scar-forming cells, myosatelite cells energized with red light will form new healthy muscle tissue. Just the other day, a friend posted an Instagram story in which she was sitting in a sauna built for one with red lights shining on her as she rolled her head to one of her Spotify playlists (because, of course, an auxiliary cable was included in said sauna). According to the first study detailed below, “NIR appears to initiate a cascade of subcellular events that can produce immediate, delayed and persistent beneficial changes in the injured neuron or other cell.

While more studies are needed, a growing body of anecdotal evidence suggests that low-level laser light therapy can alleviate symptoms and promote healing for many diseases. Red light therapy uses energy-efficient red light to activate mitochondria, which are the cell's energy generators. There are still no large studies that show that these lights are more effective than existing treatments. .
