The Benefits and Risks of Red Light and Infrared Sauna Therapies

Exploring the Benefits of Red Light Therapy and Infrared Sauna Therapy

In recent years, natural health enthusiasts have shown increasing interest in the potential benefits of red light therapy and infrared sauna therapy. Both modalities deliver concentrated wavelengths of light and heat energy to the body in non-invasive ways. Practitioners and proponents make a wide range of claims about their healing and rejuvenating powers. But what does the science say, and how can you know if these treatments are right for you? Lets take a thorough look at what each therapy involves, their proposed effects, safety considerations, costs and more.

What is Red Light Therapy?

Red light therapy involves exposing your body to concentrated red and near-infrared wavelengths of natural light. It is also sometimes referred to as low-level laser therapy (LLLT), photobiomodulation, and RLT. Infrared wavelengths penetrate beneath the skin and purportedly boost cellular function and blood flow.

Most red light therapy devices are panels or beds with powerful LEDs that emit therapeutic wavelengths. Sessions generally last 10-20 minutes as you sit or stand in proximity to the lights, allowing the rays to reach large surface areas of your body. Handheld units are also available for targeting specific points.

Proposed Benefits of Red Light Therapy

What conditions might red light therapy help with? Here are some of the most oft-cited benefits among proponents and in studies:

• Increased collagen production and wound healing
• Skin rejuvenation and anti-aging effects
• Improved joint and muscle recovery
• Pain relief for arthritis and injuries
• More energy and alertness
• Enhanced blood circulation
• Treating hair loss and stimulating regrowth

Examining the Research on Red Light Therapy

Thousands of studies have looked at red light therapy over the past 40 years. Results are mixed, but there is compelling evidence for certain applications when used correctly. Here is a sampling of what some studies have found:

• A 2014 review showed LLLT accelerated wound healing and reduced pain in some trials.
• A 2020 analysis found LLLT improved wrinkles, skin texture, and collagen activity when used consistently.
• Multiple studies, like this 2010 trial, show LLLT reduces arthritis pain and improves recovery when applied to joints.
• For bodybuilders, some research found LLLT improved exercise recovery times and reduced muscle soreness.
• Several trials, including this 2018 study, concluded LLLT stimulated hair regrowth in those with alopecia and male pattern baldness.

However, many other studies show less conclusive or contradictory evidence. Critics argue more high-quality, large-scale controlled trials are needed to verify effects. Results seem to vary based on factors like wavelength, dose, application method and health condition treated.

Are There Any Side Effects of Red Light Therapy?

Red light therapy is considered very safe with a low risk of adverse effects when used as directed. The most common side effects include:

• Mild redness or rash after treatment
• Headache
• Fatigue
• Eye strain if eye protection not worn

To reduce eye strain and potential damage, always wear provided safety goggles. Discuss any pre-existing medical conditions with your doctor first.

Who Should Not Use Red Light Therapy?

While generally very safe, the following groups should exercise caution or avoid red light therapy:

• Those with light-sensitive conditions or on photosensitizing medications
• Anyone with a cancer risk or previous skin cancer
• Those with thyroid dysfunction or taking thyroid medications
• Pregnant women
• Anyone with implants or pacing devices
• Those with acute illnesses or wounds

Talk to your doctor before starting if you have any concerns. They can help assess if red light therapy is suitable for your health status and needs.

At-Home vs Professional Red Light Therapy

There are options for red light therapy both in professional clinics and for at-home use. Professional equipment tends to be more expensive but delivers higher, calibrated doses of therapeutic wavelengths.

Home devices are more affordable and convenient, but often have lower LED power. Results may take longer at home. However, they allow more frequent treatment. Follow all safety directions when using store-bought devices.

How Much Does Red Light Therapy Cost?

Costs for red light therapy can vary greatly. Professional clinic sessions may range from $20-75 per appointment, with membership packages bringing down the per-session price. Memberships generally cost several hundred dollars.

At-home red light therapy devices have wide-ranging prices based on size, power and features. Smaller LED panels can cost $100-300, while large infrared saunas with RLT can cost $3000-5000.

Health insurance plans generally dont cover red light therapy as its still considered alternative medicine.

What is Infrared Sauna Therapy?

Infrared saunas use infrared heating elements to warm your body directly rather than simply heating the air around you. Lower temperature infrared waves penetrate just below the skin, purportedly inducing a deep, detoxifying sweat.

Infrared saunas exist in many spas and clinics, allowing you to relax in a heated chamber for guided sessions. There are also portable home units. Most experts recommend 10-30 minute sauna sessions 1-3 times per week.

Proposed Benefits of Infrared Sauna Therapy

Here are some oft-cited but debated potential perks of regular infrared sauna use:

• Detoxification - deeper sweating releases toxins
• Relaxation and reduced stress
• Eased joint pain and muscle soreness
• Lower blood pressure
• Increased circulation
• Improved complexion and skin purification
• Temporary relief of cold and flu symptoms
• Mild weight loss

Examining the Science on Infrared Sauna Benefits

Despite widespread anecdotal reports, there is still limited research directly demonstrating unique benefits from infrared specifically. However, studies show signs saunas in general may offer some advantages:

• A 2015 study found regular saunas were linked to lowered risk of high blood pressure.
• A 2016 review concluded sauna use shows promise for cardiovascular health, but more studies needed.
• A 2018 trial showed saunas reduced chronic pain after 12 weeks of regular use.
• A 2020 study found saunas lessened common cold symptoms temporarily.

Overall, more research is still needed comparing infrared to traditional saunas and steam rooms to gauge specific effects. Anecdotes are optimistic, but clinical evidence remains limited so far.

Are Infrared Saunas Safe? Potential Precautions

Infrared saunas are considered quite safe for most healthy adults. However, there are some potential side effects and precautions to keep in mind:

• Dehydration - Be sure to adequately rehydrate before and after
• Potentially unsafe for those with multiple chronic conditions
• May affect some medications
• Not recommended for children or during pregnancy
• Those with cardiovascular disease should consult a doctor first

Talk to your healthcare provider before starting infrared sauna therapy if you take medications, have existing diseases or are concerned about safety. They can help assess if its suitable for you.

Cost Comparison of Infrared Sauna Treatments

Professional infrared sauna sessions typically range from $20-50 per session at most spas and clinics. Packages can reduce the per-session cost but often run $500+.

At-home infrared sauna kits vary greatly based on size, design, power and features. Basic portable 1-2 person units can cost $1000-2000, while larger saunas with chromotherapy and oxygen therapy can cost up to $9000+.

As an alternative therapy, health insurance does not cover infrared sauna treatments. However, some accounts like FSAs may reimburse sessions prescribed for a documented medical purpose.

Comparing Red Light Therapy vs. Infrared Saunas

Red light therapy and infrared saunas offer two different forms of phototherapy. Both deliver concentrated wavelengths to the body. But there are some key differences between the modalities:

Mechanisms of Action

Red light therapy works by delivering therapeutic light wavelengths through the skin, purportedly improving cellular function. Infrared saunas heat your core body temperature to induce sweating.

Conditions Treated

Red light is often used for skin, joint and muscle treatments, while infrared saunas are touted more for detoxification and general wellness perks.

Time Commitment

Red light requires shorter, more frequent sessions (10-20 mins daily), while sauna time ranges from 20-60 mins just 1-3 times per week.

Immediate Effects

Red light has no immediate sensation, while infrared saunas make you sweat profusely during the session.

Long-term Effects

Over time, red light purportedly improves skin and muscles, while regular saunas may boost cardiovascular function and general health.

Side Effects

Red light has minimal side effects. Saunas carry higher risks of dehydration, medication interactions and other issues.

Cost Comparison

Home red light devices are generally more affordable than infrared sauna kits.

Who Might Benefit from Phototherapy?

Based on the proposed benefits, here are some people who may see results from incorporating red light therapy and/or infrared saunas:

• Those seeking anti-aging skincare who want healthier, youthful skin.
• People with chronic muscle or joint pain looking for relief.
• Athletes and active individuals aiming to improve performance and recovery.
• Anyone with stubborn injuries or inflammatory conditions.
• Those looking to relax, destress and sweat out toxins.
• People wanting to improve heart health and circulation.
• Individuals with skin conditions like eczema or psoriasis.
• Those desiring a mood boost and enhanced energy levels.

Those with chronic health issues should consult their doctor before trying saunas or light therapy.

Are Phototherapy Devices Worth the Investment?

Based on the evidence so far, is buying your own red light or infrared sauna device likely to yield tangible results? Here are a few factors to consider if debating a purchase:

Understand the Limitations of Research

While study results are intriguing, the science is still preliminary and unpredictable. Dont expect guaranteed life-changing results. Manage expectations realistically.

Consider Your Specific Needs

Those with chronic conditions shown to improve with phototherapy are more likely to benefit. If you simply want general wellness, benefits may be minimal.

Choose Quality Devices

With home devices, you often get what you pay for. Cheap low-powered units likely wont replicate pro-grade clinical devices. Vet brands thoroughly.

Commit to Regular Use

Like most treatments, consistency is key to seeing results. Occasional use wont deliver the same benefits.

Be Realistic About Costs

At-home kits provide convenience but often have higher upfront costs. If budget is a concern, pay-per-session clinic fees may be more economical.

Phototherapy shows promise, but more evidence is needed to confirm results. While generally safe, unproven treatments come with uncertainties. Talk to a doctor to see if trying devices could benefit your individual needs.
