Red Light Therapy for Artificial Light Exposure

This trial aims to determine if red light therapy (also known as photobiomodulation or low-level laser therapy) can improve blood flow in healthy adults. Participants will have their leg exposed to a specific type of red light and receive an ultrasound contrast to measure blood flow. This simple test evaluates whether the light can make a difference. Individuals who are generally healthy and do not have conditions like diabetes or heart issues may be suitable for this study. As an unphased trial, this study offers participants the chance to contribute to innovative research that could lead to new health insights.

The trial information does not specify whether you need to stop taking your current medications. It's best to discuss this with the trial coordinators or your doctor.

Research has shown that using 670 nm red light, like the one in this trial, is generally safe. Studies have found that red light therapy can improve blood flow and may even aid in brain injury recovery. This type of light is usually well-tolerated because it avoids the safety issues associated with lasers, making it easier and safer to use on large body areas.

Octafluoropropane is often used in medical imaging as a contrast agent. In this trial, it helps doctors see blood flow more clearly with ultrasound. Although detailed safety information is limited, it is commonly used in medical settings. Its use in this trial suggests a history of safety when used properly.

Researchers are excited about the use of 670 nm red light therapy for artificial light exposure because it offers a unique, non-invasive approach by using a specific wavelength of light to improve blood flow. Unlike traditional treatments that might involve medication or lifestyle changes, this therapy uses a light-emitting diode positioned above the skin, avoiding direct contact and minimizing discomfort. Additionally, the treatment is paired with octafluoropropane infusion for precise blood flow measurement, allowing for real-time assessment of its effectiveness. This innovative method could provide a quicker, more targeted solution for issues caused by artificial light exposure.

Research has shown that 670 nm red light therapy, which participants in this trial will receive, can benefit several health areas. Studies have found it improves sleep and boosts endurance in athletes. It also protects eye cells, particularly those that detect light, preventing cell death. Additionally, a single session of 670 nm light can significantly enhance the ability to distinguish between colors. These findings suggest that 670 nm light therapy might also increase blood flow, given its positive effects on cell health and function.¹³⁶⁷⁸
