What is Red Light Therapy?

Red light therapy is a treatment that uses low-wavelength red light to penetrate the skin and stimulate various cellular processes. It’s sometimes referred to as  low-level laser therapy or photobiomodulation. 

Originally used in medical settings to help with wound healing and reduce inflammation, red light therapy has since gained popularity for a range of uses, including skin health, muscle recovery, and even weight loss. The treatment itself is non-invasive and painless. You simply sit or stand near a red light panel, wear a face mask, or use a handheld device while the light works its magic on your cells.

How Does Red Light Therapy Work?

Red light therapy works by delivering specific wavelengths of red and near-infrared light to your skin, where it penetrates deep into your cells. Unlike UV light – which can damage skin – red light is thought to support cellular function by boosting mitochondria – the energy centers of your cells.

When your mitochondria absorb red light, they produce more adenosine triphosphate (ATP), which is the fuel your cells need to function. This increase in energy may help improve circulation, reduce inflammation, and support tissue repair. Some research also suggests that red light therapy could influence fat cells, potentially breaking them down or making them more accessible for energy use.

While the science is still evolving, many people use red light therapy for skin health, muscle recovery, and, more recently, weight loss.

Can Red Light Therapy Help with Weight Loss?

Red light therapy has gained attention as a possible tool for weight loss, but health experts are still exploring its effectiveness. The idea is that exposing fat cells to red and near-infrared light could help break them down, making it easier for your body to process and eliminate them. Some studies suggest that red light therapy may temporarily shrink fat cells by prompting them to release stored lipids, which your body can then use for energy.

There’s also the potential for indirect benefits. Red light therapy is thought to improve circulation, reduce inflammation, and support cellular function, all of which could play a role in metabolism and overall body composition. Some proponents claim it helps with muscle recovery and energy levels, which might encourage more physical activity – an important factor in weight loss.

That said, red light therapy isn’t a magic solution. While some research shows promise, it’s best viewed as a supportive tool rather than a replacement for healthy habits like regular exercise and a balanced diet. If you’re considering trying it, setting realistic expectations is key.

Other Potential Benefits of Red Light Therapy

Beyond its possible role in weight loss, red light therapy has been studied for a variety of other health benefits. 

Skincare

One of the most well-known uses is skin health – many people turn to red light therapy to support collagen production, reduce wrinkles, and improve overall skin tone. It’s also been explored for its ability to help with wound healing, acne, and inflammation-related skin conditions like psoriasis.

Pain relief

Another big area of interest is muscle recovery and pain relief. Athletes and fitness enthusiasts often use red light therapy to help reduce soreness, speed up recovery after workouts, and even improve performance. Some research also suggests it may help with chronic pain conditions, including arthritis and joint discomfort.

Brain function

Additionally, red light therapy is being studied for its potential effects on sleep, mood, and brain function. Since light exposure influences the body’s circadian rhythm, some people find that it helps regulate sleep patterns. There’s also emerging research into its role in reducing symptoms of depression and supporting cognitive function.

Who Should Avoid Red Light Therapy?

While red light therapy is generally considered safe, it may not be the best option for everyone. People with light sensitivity or certain medical conditions – such as lupus or epilepsy – should consult a healthcare provider before trying it, as the light exposure could trigger symptoms. Similarly, if you take medications that increase photosensitivity – like some antibiotics, acne treatments, or chemotherapy drugs – you might be more prone to skin irritation.

Those with cancer or a history of skin cancer should also be cautious. While red light therapy is sometimes used in medical settings, exposing certain types of abnormal cells to light stimulation could carry risks. Be sure to speak with your healthcare provider before trying red light therapy if you have a history with cancer to ensure safety.

Pregnant women may also want to avoid red light therapy, simply because research on its effects during pregnancy is limited.

If you have any concerns or underlying health conditions, checking with a doctor before starting red light therapy is a good idea.
