How Red Light Therapy Works

Red light therapy, also known as low-level laser therapy (LLLT) is a form of therapy that delivers energy to cells by applying a range of visible and invisible wavelengths of light.

This innovative technology has gained popularity in recent years due to its numerous benefits.

How Red Light Therapy Works

1. Low-Intensity Red Light

Joovv devices emit red and near-infrared light designed to reduce pain, relax muscles/joints, and increase blood circulation.

• Wavelength: 660 nanometers (nm) (Red) and 850 nm (Near-Infrared)

This wavelength is absorbed by cells, tissues, and organs, triggering a range of physiological responses.

2. Cellular Processes

The red light energy stimulates cellular processes, such as:

• Increased ATP production: Red light therapy can boost ATP levels, which enhances energy production and supports cellular function.
• Enhanced mitochondrial function: By increasing the activity of mitochondria (cellular powerhouses), red light therapy can improve energy metabolism and reduce oxidative stress.
• Increased blood flow: The treatment can stimulate vasodilation, improving blood circulation and delivering oxygen and nutrients to cells.

3. Tissue Repair

Red light therapy can promote tissue repair by:

• Activating cellular responses: The treatment stimulates the production of growth factors, cytokines, and other signaling molecules that support tissue repair.
• Increasing collagen synthesis: Red light therapy can stimulate the production of collagen, a crucial protein for skin, bone, and connective tissue health.

Red Light Therapy Devices:

1. Panel Lamps: These devices emit red light through a flat panel, typically used for full-body treatments or targeting specific areas.
2. Handheld Devices: Portable devices that use LED arrays to deliver targeted red light therapy.
3. Helmet Devices: Specialized helmets designed for cranial applications, such as treating headaches and migraines.

Benefits of Red Light Therapy:

1. Pain Relief: Reduces inflammation, promotes relaxation, and alleviates chronic pain.
2. Wound Healing: Accelerates wound healing, improves tissue repair, and reduces scarring.
3. Skin Health: Improves skin elasticity, reduces fine lines and wrinkles, and treats acne.
4. Hair Loss Prevention: Stimulates hair growth, improves scalp health, and reduces shedding.
5. Muscle Recovery: Enhances muscle recovery, reduces muscle soreness, and promotes athletic performance.

Side Effects and Precautions:

1. Mild Heating Sensation: Some users may feel a mild warmth or heat during treatment.
2. Slight Redness: The treated area might become slightly red or flushed due to increased blood flow.
3. Temporary Discomfort: Mild discomfort, such as tingling or numbness, may occur in some individuals.
4. Eye Strain: Prolonged exposure to red light can cause eye strain or fatigue.
5. Headaches: Rarely, some users might experience headaches due to the treatment.

Red light therapy should be used with caution during pregnancy and breastfeeding.
