Does Red Light Therapy Increase Testosterone?: Fast-Track Guide to Understanding the Impact of Red Light Therapy on Testosterone Levels

Red light therapy—also known as photobiomodulation—uses specific wavelengths of red and near-infrared light to stimulate cell activity, reduce inflammation, and accelerate healing. In recent years, there has been growing interest in whether red light therapy (RLT) can positively impact testosterone levels, especially among men looking for non-invasive methods to boost hormonal health.

Current scientific evidence provides some support for the idea that red light therapy may help increase testosterone production. A few small-scale studies and animal experiments have shown that applying red or near-infrared light to the testes can stimulate Leydig cells, which are responsible for testosterone synthesis. Additionally, anecdotal evidence from biohackers and medical spas suggests that some men experience higher energy, libido, and mood following consistent treatments.

However, it’s important to note that most research in this area is limited, and larger, controlled human studies are needed to verify these effects and establish safety protocols, such as appropriate wavelengths, duration, and treatment frequency.

As an interior designer, I approach red light therapy from an experiential perspective. The integration of therapy devices into a dedicated home wellness space can support consistency and relaxation—crucial for realizing health benefits. Crafting a calm, purpose-built environment allows users to enjoy their therapy both safely and comfortably at home. For example, arranging your wellness area thoughtfully and experimenting with various room layouts can make red light therapy a more enjoyable, sustainable addition to your self-care routine.

Tips 1:

When considering red light therapy, always consult a medical professional before use—especially for hormonal health. Set up your therapy area in a quiet, private space with adequate ventilation and easy access to power outlets. Incorporate comfortable seating, relaxing colors, and soft lighting to optimize your experience.
