In the world of at-home wellness, two types of high-tech therapy blankets are getting much attention: red light therapy blankets and infrared sauna blankets. Both promise impressive benefits, from better skin and muscle recovery to stress relief and detoxification. But before you invest, it’s essential to know how they differ and which one is right for you. Let’s dive into the details.

Red Light Therapy Vs. Infrared Therapy

Red Light Therapy

Red light therapy (RLT) is a non-invasive treatment that uses low-level wavelengths of red light to stimulate cells and promote healing. The wavelengths, typically between 600 and 700 nanometers (nm), penetrate the skin, activating biological processes in your cells. Red light therapy enhances the energy-producing components in your cells called mitochondria. When your cells have more energy, they can function more efficiently, repair damage faster, and rejuvenate tissues. This makes RLT popular in the skincare and sports recovery world.

Red light therapy is also known as:

• Low-level laser light therapy.
• Low-power laser therapy.
• Soft laser therapy.
• Non-thermal LED light.
• Cold laser therapy.
• Photobiomodulation and phototherapy.
• Biostimulation, photonic stimulation.

Infrared Therapy

Far-infrared (FIR) wavelengths are used in infrared treatment to penetrate deeply into bodily tissues, generally to depths that red light therapy cannot reach. Unlike visible red light, FIR is invisible to the human eye. Infrared heat penetrates skin and muscle tissues, raising body temperature and causing a sauna-like sweating effect. This procedure is believed to improve circulation, cleansing, and relaxation. FIR is often used in sauna blankets and sauna rooms to provide a warm, sweaty experience that resembles traditional sauna benefits.

Red Light Therapy Blankets Vs. Infrared Sauna Blankets

How Red Light Therapy Blankets Work

Red light therapy blankets are equipped with red LED lights that emit the optimal wavelengths for cellular absorption. These lights are arranged in patterns across the blanket’s surface, allowing for even exposure to the body. When in use, the blanket emits a gentle glow but doesn’t generate heat, making it comfortable for long periods.

Benefits of Red Light Therapy Blankets

Here are some common advantages of red light therapy blankets:

• Reduce stretch marks.
• Improve wound healing.
• Reduce age spots, wrinkles, and fine lines.
• Improve facial texture.
• Improve scars.
• Improve eczema, psoriasis, and rosacea.
• Improve sun-damaged skin.
• Improve acne.
• Improve hair growth in individuals suffering from androgenic alopecia.

Side Effects of Red Light Therapy Blankets

Over 4,000 studies on red light therapy have shown no significant side effects to date. However, it’s crucial to always follow the usage instructions provided with any red light therapy device. 

Before trying a Red Light Therapy Blanket for the first time, make sure to perform a photosensitivity test. While red light itself hasn’t been linked to eye damage, the brightness of some devices can be uncomfortable for those sensitive to light. Therefore, if you are light-sensitive, using protective goggles during your sessions is essential.

How Infrared Sauna Blankets Work

Infrared sauna blankets use FIR technology to produce heat, simulating the effects of a traditional sauna but in a portable and convenient form. As the blanket warms up, it raises the body temperature, causing sweat production. This makes infrared sauna blankets ideal for those who enjoy the sensation and benefits of a sauna session at home.

Benefits of Infrared Sauna Blankets

• Detoxification
• Relaxation
• Pain relief
• Stress reduction
• Improved skin health 
• Improved sleep 
• Improved cardiovascular health
• Boosted immune system

Side Effects of Infrared Sauna Blankets

There’s no evidence indicating that infrared sauna blankets are unsafe; however, it’s still crucial to consult a doctor before using one. Pregnant women should avoid any type of sauna therapy. 

Additionally, anecdotal reports suggest that people with heart conditions should steer clear of sauna therapy, possibly because the heat and humidity can strain the cardiovascular system. 

Children should spend less time in a sauna blanket compared to adults, and research from 2021 suggests that children under the age of 6 should avoid this therapy entirely, as their bodies are less efficient at regulating heat and sweating, putting them at risk of overheating.

Key Differences Between Red Light and Infrared Sauna Blankets

1. Mechanism of Action

• Red Light Therapy: Works by stimulating cellular energy and promoting tissue regeneration. It does not use heat.
• Infrared Therapy: Uses heat to increase body temperature, causing sweating and promoting detoxification.

2. Heat vs. No Heat

The primary difference is that infrared sauna blankets generate heat to induce sweating, whereas red light therapy blankets do not. Infrared heat can penetrate deep into the skin, producing a sauna effect, while red light therapy provides cellular-level benefits without affecting body temperature.

3. Primary Benefits: Skin Health vs. Detoxification

Red light therapy is focused on skin health, cellular regeneration, and healing, making it ideal for those looking to improve skin tone and reduce signs of aging. Infrared sauna blankets, on the other hand, excel at detoxification, weight management, and relaxation, as they induce sweating and increase circulation.

4. Session Experience

Red light therapy sessions are typically shorter (10–20 minutes) and don’t require you to break a sweat. While, infrared sauna therapy sessions last 30–45 minutes, with sweating and heat intensity being major elements.

Safety Considerations and Precautions

Both red light therapy and infrared sauna blankets provide significant benefits, but it is crucial to use them carefully.

• Hydration: For infrared sauna blankets, staying hydrated is crucial to prevent dehydration from sweating.
• Session Duration: Limit sessions according to recommended guidelines to avoid overexposure, especially with infrared heat.
• Consultation: Consult a healthcare provider before beginning red light or infrared therapy, especially if you have a medical condition, are pregnant, or are sensitive to light or heat.
