Red Light Therapy Panels vs. Infrared Saunas? Which is Right for You?

Curious about red and infrared light therapy versus infrared saunas? We get this question all of the time! In our latest blog, we break down the key differences so you can decide which option is best for your wellness journey. Though spoiler alert, we think red and infrared light therapy is the superior option at an affordable price!

Infrared saunas primarily emit mid-infrared and far-infrared wavelengths, which are focused on generating heat. These wavelengths penetrate the skin's surface and deeper tissues, causing a warming effect that promotes sweating, detoxification, and circulation. The primary mechanism of infrared saunas is thermal, relying on heat to achieve therapeutic benefits.

In contrast, red light therapy devices typically emit red (around 620–750 nm) and near-infrared (around 700–1100 nm) wavelengths at higher concentrations. These wavelengths penetrate tissues more deeply than visible light but do not produce significant heat. Instead, they work through a process called Photobiomodulation, where the light stimulates cellular components—especially mitochondria—enhancing energy production (ATP). This cellular stimulation promotes healing, reduces inflammation, and improves skin health, often without any noticeable increase in temperature.

Infrared Saunas
Wavelengths Emitted: Primarily mid-infrared (approximately 1000–3000 nm) and far-infrared (approximately 3000–10,000 nm).
How They Work: These wavelengths produce thermal energy that heats the skin and underlying tissues. The heat penetrates the body, leading to sweating and increased blood circulation.
Main Effects: The primary goal is to induce deep, whole-body warmth, which can promote detoxification through sweating, relax muscles, reduce pain, and improve cardiovascular health.
Heat Production: Yes, they generate significant heat, which is the primary therapeutic mechanism.

Red Light Therapy Panels
Wavelengths Emitted: Usually emit red light (around 620–750 nm) and near-infrared light (around 700–1100 nm), with a focus on near-infrared.
How They Work: These devices deliver specific wavelengths of light directly to targeted areas of the skin. The light penetrates the skin and reaches deeper tissues, especially at near-infrared wavelengths.
Main Effects: They enhance mitochondrial function within cells, leading to increased production of ATP (cellular energy). This can promote tissue repair, reduce inflammation, improve skin health, and boost overall cellular vitality.
Heat Production: Minimal to none; the primary mechanism is Photobiomodulation (light-based stimulation), not heat.
