Red Light Therapy Blankets – How Do They Work?

A Red Light Therapy Blanket is a full-body wellness device fitted with red and near-infrared LEDs. Its cocoon-style design surrounds the body, making it a convenient way to incorporate light sessions into a relaxation or post-workout routine.¹

Unlike a traditional panel, the blanket delivers light to the front and back of the body during the same session. The BON CHARGE Red Light Therapy Blanket can also be unzipped into two separate mats for targeted or shared use.

Red light therapy technologies have become increasingly popular with people looking for a convenient way to enjoy full-body red and near-infrared light sessions at home.

What is the Difference between a Red Light Therapy Blanket and Infrared Sauna Blanket?

Although they look similar, BON CHARGE’s Red Light Therapy Blanket and Infrared Sauna Blanket use different technologies and provide different wellness experiences.

A Red Light Therapy Blanket uses LEDs to deliver visible red and invisible near-infrared light. This approach is commonly known as photobiomodulation.²

An Infrared Sauna Blanket, on the other hand, uses far-infrared heat to create a warming, sauna-like experience. It is designed to encourage perspiration, relaxation and post-workout comfort.

A Red Light Therapy Blanket focuses on light exposure, while an Infrared Sauna Blanket focuses on heat. The right option therefore depends on the experience you want to add to your wellness routine.

How impactful are red light therapy blankets?

The Red Light Therapy Blanket offers a convenient way to expose large areas of the body to red and near-infrared light during one session.

With a panel, users may need to change position to expose the front and back of the body. A zipped blanket surrounds the body, allowing both sides to receive light at the same time.

The BON CHARGE Red Light Therapy Blanket delivers an irradiance of approximately 170 mW/cm² and uses 2,520 LEDs. The blanket wraps around your body, keeping the LEDs close without needing to position yourself at a set distance from a panel.¹

It is important to remember that higher irradiance does not automatically mean better results. The overall light dose also depends on factors such as exposure time, wavelength and treatment protocol.³ Always follow the instructions in the product manual rather than extending sessions beyond the recommended duration.¹

How do red right therapy blankets work?

The BON CHARGE Red Light Therapy Blanket plugs into a mains power supply and is operated using handheld controllers.

The Red Light Therapy Blanket uses 660 nm red light and 850 nm near-infrared light. It offers adjustable intensity as well as constant-light and pulsed modes at 10 Hz and 40 Hz, allowing users to tailor each session to their preferences.¹

The blanket consists of two mats that zip together to create a cocoon-style design. They can also be separated for targeted sessions, yoga or Pilates routines, or used by two people at the same time.

The recommended session range is 5–20 minutes. Lay the blanket on a flat surface, connect both controllers and select the desired settings before getting comfortable. If looking directly at the lights, wear the supplied goggles during your session, and do not exceed 30 minutes per session.¹

What are the benefits of red light therapy blankets?

• A Red Light Therapy Blanket can complement several wellness goals, including post-workout recovery, relaxation and skincare routines.
• Research on red light therapy technologies suggests that photobiomodulation may support certain aspects of exercise recovery. However, outcomes vary according to the device, wavelength, light dose, timing and protocol used.⁴˒⁵
• Red and near-infrared light have also been studied for their potential to support aspects of skin appearance, including texture and the appearance of fine lines.⁶ Research into photobiomodulation covers many different devices and protocols, so findings should not be interpreted as clinical evidence for every consumer product.
• One of the blanket’s benefits is convenience. Its cocoon-style format delivers light across a large surface area without requiring the user to stand in front of a panel or change position halfway through a session.
• The close-contact design also makes it easy to use while relaxing, reading, meditating or winding down in the evening. This can make regular sessions easier to incorporate into an existing self-care routine.
• The two sections can also be separated and used as individual mats. This provides greater flexibility for individual or shared sessions, although only the side facing the LEDs will receive light when a single mat is used.

What are the negatives of red light therapy blankets?

• A premium Red Light Therapy Blanket can represent a significant upfront investment. Devices with extensive LED coverage, adjustable controls and durable materials generally cost more than smaller, targeted products.
• A blanket is also less portable than a handheld device and requires a suitable flat surface for use. The BON CHARGE model measures 180 cm × 80 cm and weighs approximately 10 kg, so it is worth considering how and where it will be used and stored.¹
• The cocoon format may feel more enclosed than using an open panel. People who prefer a standing session or want to focus on one small area may find a panel or handheld device more suitable.
• As with any wellness practice, individual experiences can vary. Consistent and recommended use as per the user manual, alongside realistic expectations, is important.

Are red light therapy blanket safe?

Photobiomodulation is generally well tolerated in published research, but individual responses can vary.⁷,8 Always use a Red Light Therapy Blanket according to the instructions for use.¹

Read the full user manual, including the safety instructions and contraindications, and complete the recommended light-sensitivity test before your first full session. The BON CHARGE Red Light Therapy Blanket includes protective goggles which should be used as directed and avoid looking directly at the LEDs.¹

Speak with a qualified healthcare professional before use if you are pregnant, have a light-sensitive condition, take photosensitising medication or are unsure whether the product is suitable for you.

Do not exceed the recommended session length. The product is intended as a consumer wellness device and is not designed to diagnose, treat, cure or prevent any disease.

What’s the best red light therapy blanket?

When choosing a Red Light Therapy Blanket, compare more than price alone. Important factors include wavelengths, irradiance, LED coverage, adjustable settings, materials, safety certifications, warranty and access to customer support.

The BON CHARGE Red Light Therapy Blanket combines 660 nm red light and 850 nm near-infrared light with an irradiance of approximately 170 mW/cm² and 2,520 LEDs. It also offers adjustable intensity, standard and pulsed modes, a recommended 5–20-minute session time and a one-year warranty.¹ 

Its two-mat design provides the flexibility to use it as a full-body blanket or as separate mats for individual and shared sessions. For anyone looking to make red and near-infrared light part of a consistent at-home routine, it offers a convenient, full-coverage option.
