Summary | This is how light therapies work!

How does red light therapy work?
Red Light Therapy uses visible light within a specific wavelength range to stimulate your cells. It penetrates the outer layers of the skin and reaches the mitochondria, the energy factories of your cells. As a result, the production of adenosine triphosphate (ATP), your body's primary energy source, increases, accelerating recovery and growth.
Red light feels comfortable, does not emit heat, and is safe for the skin and eyes when used correctly.

Wavelengths
Red light falls within a wavelength range of 600 to 700 nanometers. These wavelengths penetrate deep into the skin, reaching several millimeters. This stimulates the mitochondria in your cells, your body's energy factories. As a result, ATP production increases, supporting cell repair and growth.

Applications & Benefits
red light therapy has many applications and benefits:
- Reduction of inflammation: Helps your body recover faster from injuries or irritations.
- Wound healing: Promotes the regeneration of skin cells for faster healing.
- Skin improvement: Stimulates collagen production for a smooth, radiant complexion.
- Pain relief: Relieves muscle and joint pain, such as pain caused by arthritis or sore muscles.
- Better sleep quality: Supports your natural sleep rhythm and reduces stress.
Using red light lamps
Would you like to try red light therapy at home? Follow these guidelines:
- Duration: 10 to 20 minutes per session
- Distance: 15 to 30 centimeters from the skin
- Frequency: Start with 3 to 5 times per week (you can increase this later)

How does infrared light therapy work?
Infrared therapy uses light with longer wavelengths that penetrate deeper into your body. This light reaches muscles, joints, and tissues, where it generates heat and activates recovery processes.
The deep heat relaxes muscles, stimulates blood circulation, and accelerates healing. Infrared light relieves pain, reduces stiffness and swelling, and helps your body relax. It is therefore used both in therapeutic treatments and for general relaxation.

Wavelengths
Infrared light is divided into 3 categories of radiation: A, B, and C (or IR-A, IR-B, and IR-C). This classification is based on the wavelength of the infrared light:
- Short-wave infrared (IR-A): wavelength from 0.78 µm to 1.4 µm (1 µm = 1000 nanometers)
- Mid-wave infrared (IR-B): wavelength from 1.4 µm to 3 µm (1 µm = 1000 nanometers)
- Long-wave infrared (IR-C): wavelength from 3 µm to 1,000 µm (1 µm = 1000 nanometers)

Applications & Benefits
Infrared therapy offers profound benefits for your health. For example:
- Deep pain relief: Reduces muscle stiffness and joint pain through deep-penetrating heat.
- Faster recovery: Speeds up muscle and tissue recovery after exercise or injuries.
- Improved circulation: Supports better oxygen supply and cell recovery.
- Chronic conditions: Helps with complaints such as arthritis and fibromyalgia.
- Stress reduction: Relaxes your muscles and calms your mind for greater balance.
Instructions for use
Would you like to try infrared light therapy at home? Follow these guidelines:
- Duration: 10–15 minutes per body part
- Distance: 50–100 cm from the body
- Frequency: 3–4 times per week

Want to know more about the differences?
Red Light Therapy and Infrared therapy are often mentioned in the same breath, but as you can read above, they are different treatments. For a clear overview of the key differences, we have written an extensive blog post, which you can read here: “Infrared or red light: What is the difference?”
Summary | This is how light therapies work!
Red Light Therapy uses visible light that penetrates your skin to give your cells a boost. It helps reduce inflammation, promotes recovery, and gives you radiant skin.
Infrared therapy goes even deeper. Thanks to its longer wavelengths, it relaxes your muscles, improves circulation, and relieves pain. Ideal after a long day!
Both therapies offer great benefits, each in their own way. Choose what suits you best and experience the power of light for yourself!
