Discover how red light therapy beds use therapeutic wavelengths for skin health, muscle recovery & pain relief. FDA-cleared devices, clinical studies, safety guide & expert tips.
Ever wondered why so many people are talking about red light therapy beds? These full-body devices utilize specific wavelengths of light to support skin health, alleviate muscle soreness, and promote recovery after physical activity.
A red light therapy bed exposes your entire body to low-level red light, which may improve your overall well-being and appearance without exposing you to harmful UV rays.
You might think of a tanning bed, but this is different. Instead of darkening your skin, a red light therapy bed works at the cellular level to promote balance and wellness.
It is used in spas, gyms, and even at home for simple daily care.
If you want to know how these beds work, what benefits they offer, and if they are safe, this guide will walk you through it step by step.

A red light therapy bed is a full-body device that utilizes specific wavelengths of light to support skin health, promote muscle recovery, and alleviate pain. It resembles a tanning bed but does not use UV light, making it safer for regular use.
When you lie in a red light therapy bed, hundreds of small LED bulbs or low-level lasers shine light directly onto your skin.
These lights usually fall within the red range of 625 to 670 nanometers and the near-infrared range of 830 to 850 nanometers.
Your cells absorb this light, which helps increase energy production in the mitochondria. This process is known as photobiomodulation.
More energy in your cells can support tissue repair, reduce inflammation, and improve circulation.
Unlike tanning beds, red light therapy beds do not release UV rays. This means you can use them without the risk of sunburn or skin damage. The treatment is non-invasive and does not require recovery time.
A red light therapy bed is built with panels lined with hundreds or even thousands of LEDs. These lights are set to emit both red and near-infrared wavelengths.
Red light mainly affects the skin surface, while near-infrared light penetrates deeper into muscles and joints.
Some beds are designed as Class II medical devices, which means they meet certain safety and performance standards. These models are often used in clinics and wellness centers.
The technology focuses on delivering an even spread of light across your body. Good-quality beds ensure consistent intensity, so that every area of your skin and tissue receives the same exposure.
Some advanced models also allow you to adjust light settings for specific needs.
Red light therapy beds utilize specialized lights to stimulate your cells and promote healing. The two main types are red light and near-infrared light, and some beds combine both. Each type has unique benefits for your body.
Here's a simple breakdown:
Penetration: Works on the surface of the skin
Benefits: Supports skin rejuvenation, helps reduce acne, and aids wound healing
Visibility: You can see it with your eyes
Penetration: Penetrates significantly deeper, reaching several centimeters below the skin to affect muscle, nerve, and other deeper tissues
Benefits: Relieves pain, reduces swelling, and speeds up muscle and joint recovery
Visibility: You cannot see it, but you may feel warmth on your skin
Benefits: Treats both surface skin problems and deeper tissue issues
Effectiveness: More complete support for overall wellness
A red light therapy bed and a tanning bed may look similar, but they work in very different ways.
You use a tanning bed to get a darker skin tone, while a red light therapy bed is meant for skin care and wellness.
The main difference is the type of light. Tanning beds use UV light that changes your skin color. Red light therapy beds use visible red and near-infrared light that does not cause tanning or burning of the skin.
Here are some clear differences:
You can think of it this way: a tanning bed changes how your skin looks on the surface, while a red light therapy bed works below the surface without causing a tan.
Some gyms and spas even offer hybrid beds that combine both types of light. If you use one of these, ensure you understand when the UV lights are on, as that is when the higher risks are present.
Red light therapy beds use specific wavelengths of light to target your muscles, joints, skin, and cells.
The main benefits include faster recovery after physical activity, reduced joint and muscle discomfort, decreased inflammation, and visible improvements in skin health.
You can use red light therapy to support faster muscle recovery after workouts or physical strain.
The light stimulates energy production in your cells, which helps your muscles repair and rebuild more efficiently.
This is especially useful if you exercise frequently or experience muscle soreness.
Regular sessions also improve circulation, which brings more oxygen and nutrients to your muscles. Better blood flow can reduce fatigue and help you recover more quickly after intense activity.
Some athletes use it to enhance performance. By supporting recovery and reducing downtime, you may find it easier to stay consistent with training and avoid long breaks due to soreness or injury.
Key points for muscle recovery:
Red light therapy is often used to ease joint pain and stiffness. The light penetrates deep into tissues, where it can support cellular repair and reduce discomfort.
This makes it a helpful option for those dealing with arthritis and chronic pain conditions, or joint injuries.
It can also improve flexibility by reducing joint stiffness. Many people notice that movement feels easier after regular use.
For muscle pain, the therapy may lessen tension and allow you to stay more active. While it is not a cure, it can be a supportive tool for managing daily discomfort.
Helpful effects for pain and joints:
Inflammation is a common cause of pain, swelling, and slower healing. Red light therapy helps reduce inflammation by calming overactive cellular processes and supporting balance in the body.
Lower inflammation can help you recover from injuries more quickly and may reduce flare-ups in chronic conditions.
If you experience swelling after workouts or daily activities, this therapy can help provide faster relief.
According to research published in the Journal of Clinical Medicine, reducing inflammation may help improve circulation and tissue repair. This makes it a useful option not only for athletes but also for anyone managing ongoing health challenges.
Ways it helps with inflammation:
Red light therapy is well known for its effects on skin health. According to clinical research in photomedicine, the light stimulates collagen production, which helps maintain the firmness and smoothness of your skin.
Collagen also supports wound healing and reduces the appearance of fine lines.
It can improve skin tone by increasing blood flow and cell turnover. This may help with scars, age spots, or uneven texture.
For anti-aging, consistent use often leads to healthier, more resilient skin. Many people notice improvements in elasticity and hydration after regular sessions.
Skin benefits you can expect:
Using a red light therapy bed involves short, timed sessions where your body is exposed to safe light wavelengths. You should know how long to stay in the bed, how often to use it, and what you will feel during treatment.
Most people start with 10 to 20 minutes per session. This time frame is long enough for the light to reach your skin and tissues but short enough to avoid overuse.
For beginners, it is best to begin at the lower end of the range. You can increase the time gradually as your body adjusts.
How often you use the bed depends on your goals. For general wellness or skin health, 3 to 4 sessions per week is common. If you are targeting muscle recovery or joint support, you may benefit from using it more frequently at first.
Over time, many people reduce their sessions to 1 to 2 per week for maintenance. Consistency is more important than long sessions, so regular, shorter treatments tend to give better results.
When you lie in bed, you will notice a gentle warmth from the lights. The treatment should not cause pain, burning, or discomfort.
It is important to protect your eyes. Most beds come with protective goggles that you should wear during every session.
Here is what you can expect:
The process is simple and does not require any special preparation other than clean skin and proper eye protection.
Yes, red light therapy beds are generally safe when used correctly and with high-quality devices.
Most problems occur when the therapy is misused, when someone has a health condition that makes them sensitive, or when it is combined with treatments that don't interact well together.
Most people don't have issues, but some mild effects can show up:
Do not mix red light therapy with UV tanning beds.
UV light can damage your skin and reduce the benefits of red light therapy.
Some groups should avoid or check with a doctor before trying red light therapy:
Research indicates that red light therapy can help enhance skin health, reduce inflammation, and promote muscle recovery.
A study in Photomedicine and Laser Surgery demonstrated clinical benefits for acne, wound healing, and fine lines, though results vary depending on the device and treatment schedule.
Research from the American Academy of Dermatology shows that some red light devices have been cleared for specific uses, including reducing pain and treating minor skin conditions.
However, not all products are FDA-cleared, so you should check the certification through the FDA's medical device database before starting treatment.
Key findings from studies include:
Most evidence supports its safety, but long-term research is still limited, so it is best to use it under guidance and moderation.
A red light therapy bed provides a safe and simple way to support your skin, muscles, and overall well-being. You can use it at a wellness center or add it to your home routine.

A red light therapy bed can target your whole body at once, but its effects depend on how you use it and what you expect from it. You will need to consider treatment goals, frequency, and the type of device before deciding if this option is right for you.
Research shows that red light therapy may support fat reduction by affecting fat cells, but it is not a direct weight loss solution. You should not rely on it as a replacement for diet and exercise. At best, it may serve as a supportive tool alongside healthy lifestyle habits.
Red light therapy beds use red and near-infrared light to stimulate cellular activity. Studies suggest they may help with skin appearance, recovery, and circulation. Results can vary, and consistency matters for noticeable effects.
Most people use a red light therapy bed several times per week at first. Sessions often last between 10 to 20 minutes. Over time, you may reduce frequency to maintain results, but the exact schedule depends on your goals and how your body responds.
You can wear minimal clothing or a swimsuit to allow more skin exposure to the light. The light does not damage skin, so direct contact is safe. Avoid wearing thick fabrics that block the light.
A bed covers your entire body in one session, which saves time and ensures even exposure. A handheld device works best for small, targeted areas. Your choice depends on whether you want full-body treatment or spot treatment for specific concerns.
