Testosterone is more than a muscle-building hormone. It plays a role in energy, motivation, mood, fat distribution, recovery and focus, and levels can naturally decline with age or under sustained stress. As interest in men’s health grows, many are looking at natural, non-invasive ways to support their overall wellbeing, and red light therapy has become part of that conversation.

Red light therapy is a recovery and wellbeing tool, not a substitute for medical care.

What is red light therapy?

Red light therapy, also known as photobiomodulation, exposes the body to specific wavelengths of red and near-infrared light, typically in the 600 to 850nm range. These penetrate the skin and stimulate the mitochondria, the cell’s energy centres, and are associated with:

• Increased ATP (energy) production
• Improved blood flow
• Reduced oxidative stress
• Cellular regeneration

Some early research has also explored whether light exposure may influence cells involved in hormone production, though this area is still developing.

What does the research say?

Interest in red light and men’s health is growing, but the evidence is early. A small 2016 study from the University of Siena reported changes in testosterone in men after light exposure, and some animal studies have looked at near-infrared light and testicular function. Human research remains limited and preliminary, so red light therapy is best seen as a general wellbeing and recovery tool rather than a treatment for hormonal conditions. If you’re concerned about your testosterone levels, speak to a doctor.

Red light and everyday recovery

Beyond the emerging hormone research, red and near-infrared light is more established as a tool for recovery and wellbeing. Many men use it to support muscle recovery, skin health, circulation and sleep, as part of a broader routine alongside training, sauna and cold exposure.

Full-body beds and wearables

Full-body red light therapy beds, like those in the Ember and Ice red and LED range, deliver consistent, even coverage. Alongside them, a new wave of compact, wearable red light devices is emerging for convenient daily use. At Ember and Ice, we’re following these developments and plan to introduce wearable options as part of our red light range.

How to use red light therapy

As general guidance rather than medical advice:

• Timing: 10 to 20 minutes per session, 3 to 5 times a week
• Wavelength: 660nm (red) and 850nm (near-infrared)
• Distance: 6 to 12 inches from a panel, or as directed for wearables
• Consistency: regular use, daily or every other day, gives the best results

The takeaway

Red light therapy is becoming an accessible, everyday tool for men focused on recovery, performance and general wellbeing. It isn’t a pharmaceutical or a hormone treatment, but as part of a considered routine, many men find it a valuable addition.

Red light therapy is intended for general wellbeing and recovery and is not a medical treatment. It is not intended to diagnose, treat or manage any hormonal or medical condition. If you have concerns about testosterone or your health, speak to a qualified medical professional.
