Does Red Light Therapy Increase Testosterone? What Science Actually Says

Summary:

For those who are wondering, does red light therapy increase testosterone? Here’s a blog to delve into the answers. Red light therapy may support testosterone indirectly by improving sleep, reducing inflammation, and enhancing cellular energy. However, current human evidence is limited, and it should not be considered a primary treatment for increasing testosterone.

Introduction

Low energy, poor recovery, reduced libido, and lack of motivation are some subtle signs that push people to question their testosterone levels, and there’s a broader trend behind this concern: Studies show that the average testosterone levels have been steadily dropping by about 1% annually since the late 1980s. (Source) Naturally, millions of men worldwide are constantly looking for natural, non-invasive ways to increase their testosterone levels, but many wellness trends lack the scientific rigor necessary to justify their use. However, that’s where a common question comes up: Does red light therapy increase testosterone?

We are going to answer this and break down what science actually says about red light therapy increasing testosterone.

What is Red Light Therapy?

Also known as photobiomodulation, Red Light Therapy (RLT) uses specific wavelengths of light to stimulate cellular activity. For instance, devices like the BL1 use wavelengths, such as:

• 610 nm (Orange light)
• 630nm (Red/ Orange light)
• 670nm (Red light)

These wavelengths interact with a key enzyme in the body known as cytochrome c oxidase, which plays a crucial role in cellular energy production, and here’s how things proceed:

• Light penetrates the skin
• It stimulates mitochondria (your cells’ energy centers)
• ATP (cellular energy) production increases
• Cells function more efficiently

This is why red light therapy is often used for:

• Muscle recovery
• Skin rejuvenation
• Reducing inflammation
• Improving sleep
• And more

However, how does this relate to testosterone? Well, we are going to see.

Does Red Light Therapy Increase Testosterone?

Short answer is: it might help, but the evidence is still emerging. Here’s what research currently suggests.

• Some animal studies published on PubMed show increased testosterone levels when red light is applied to reproductive tissues.

• On the other hand, a 2024 human trial published in the Journal of Lasers in Medical Sciences investigated the use of 650 nm and 820nm low-level laser irradiation. The researchers found that this therapy led to better sexual satisfaction and reduced chronic testicular pain, though it is important to note that testosterone was not the primary measured hormone in this specific study.

In addition, one study found that men exposed to bright light experienced a significant increase in testosterone levels over two weeks. (Source: Science Direct) Although this study used bright white light, recently red light to boost testosterone has been in use for a wide range of reasons.

How Red Light Therapy May Support Testosterone?

Though direct evidence is limited, the underlying biology offers some crucial clues in terms of how red light therapy can increase testosterone:

• Cellular Energy and Hormone Production: Primarily, testosterone production depends on the energy at the cellular level, and by improving mitochondrial function, red light therapy can support hormone-producing cells.
• Reduced Inflammation: Chronic inflammation can negatively affect hormonal balance, but red light therapy is widely known for its properties to reduce inflammation, which may indirectly help to support testosterone.
• Better Sleep Quality: Studies have shown that testosterone levels naturally peak during sleep (Source), and red light therapy commonly helps to improve sleep quality and support circadian rhythm. Also, better sleep can invariably and implicitly help with better endocrine regulation.
• Stress Reduction: Lower stress levels may also support healthier testosterone levels, and red light therapy is often associated with improved stress tolerance as it helps to lower cortisol. (Source)

Real-World Benefits Beyond Testosterone

Along with boosting testosterone, red light therapy also offers several well-documented benefits, including the following:

• Increase in energy and metabolism
• Better sleep quality
• Lowering pain and inflammation
• Supporting muscle recovery
• Improving skin health and collagen production
• Enhancing overall well-being

Besides, some users also report improvements in libido, which may also contribute to the perception of hormonal benefits.

Safety Considerations

Before you go for red light therapy, here are some safety tips that you can closely keep an eye on:

• Avoid direct eye exposure
• Follow recommended usage durations
• Use the devices as instructed

Who Should Consider It?

We would say that red light therapy may be useful if you:

• Want a non-invasive wellness tool
• Struggle with sleep or recovery
• Experience low energy or high stress

However, if you suspect clinically low testosterone, it’s crucial to consult a healthcare professional for targeted impact.

Conclusion

Red light therapy does not directly boost testosterone in a proven, clinically significant way, at least based on current human evidence. If you want to improve overall health, recovery, and energy, red light therapy can be a remarkable addition to your routine. Just keep your expectations realistic, and use the device as suggested.
