Introduction: Red Light Therapy for Blood Sugar Support

Maintaining balance in all aspects of life is essential, and the same is true for the nutrients in our bodies. One such vital nutrient is carbohydrates, which the body converts into blood sugar. Regulating blood glucose levels is necessary since an imbalance can negatively affect blood circulation and the body's general functioning. Red light therapy has been recognized as a potentially effective tool in sustaining blood sugar levels. In this article, we'll explore how red light therapy may help regulate blood sugar and balance glucose without invasive procedures.

Understanding Blood Sugar and Insulin Resistance

Blood sugar, or blood glucose, refers to the amount of sugar in your blood. Most foods contain carbohydrates, which your cells use to make ATP (the cell's energy currency). Processes like glycolysis and the Krebs cycle break down carbohydrates to generate ATP, which provides energy to the cells. This means that without carbohydrates, energy generation is impossible.

Insulin plays a crucial role in keeping the glucose level in your blood balanced. This hormone assists in turning surplus sugar into glycogen, which is stored in the liver or muscles. Unfortunately, certain conditions-such as being overweight, physical inactivity, poor diet, chronic stress, and genetics-can cause insulin resistance. When this occurs, the body's cells no longer respond to insulin typically. Consequently, too much glucose circulates in the blood, which can impact blood flow, damage cells, and cause long-term problems.

Common Challenges in Managing Blood Sugar Levels

Controlling blood sugar levels, particularly for people with diabetes, can be very difficult. Unhealthy eating habits, such as consuming too much sugar or refined carbohydrates, can cause an imbalance in blood sugar levels. Insufficient physical activity or hormonal imbalances such as PCOS and hypothyroidism can also complicate glucose control. Stress is another key factor because it triggers the body to secrete cortisol, which can lead to elevated blood sugar levels. Stress can also lead to emotional eating and sleep deprivation, further complicating glucose management.

Regarding treatment, individuals with diabetes are often recommended insulin injections, but these only provide temporary relief. Certain medications can also have side effects or may not be effective alone. However, other treatments, such as red light therapy, hold promise for those looking for a natural means to better control blood sugar levels.

How Red Light Therapy Affects Glucose Metabolism

Scientific Mechanism: Light, Mitochondria, and Sugar Regulation

Red light therapy is a seemingly magical method for ensuring healthy blood sugar levels. It accomplishes this by delivering specific wavelengths of red and near-infrared light to the body. This non-invasive method improves circulation and supports balanced blood glucose levels.

Red light therapy increases the functioning of mitochondria, the cell's powerhouse, which generates ATP (energy) by breaking down macromolecules, particularly carbohydrates. The added energy from this system assists cells in utilizing insulin more effectively.

Inflammation is a known cause of insulin resistance, but red light therapy can reduce it by encouraging anti-inflammatory responses. Some research has also shown that it enhances the body's sensitivity to insulin, especially in fat and muscle tissues. This means that the body can transport sugar from the blood to the cells more effectively.

Moreover, red light therapy improves blood flow by promoting nitric oxide synthesis, a molecule that causes blood vessels to dilate. In general, red light therapy can help control blood sugar levels naturally and without side effects.

Does Red Light Therapy Help with Diabetes? What Research Says

Research indicates that red light therapy can be a useful tool for managing blood sugar, particularly for type 2 diabetes. Red light therapy has been shown to increase mitochondrial function, resulting in better energy production and carbohydrate breakdown. It also enhances insulin sensitivity, decreases inflammation, and increases blood flow.

Key Clinical Studies on Red Light Therapy for Blood Sugar Control

Study 1: Effect of Photobiomodulation (PBM) with 670 nm Red Light on Blood Glucose Levels

Objective

To analyze the effects of photobiomodulation (PBM) with 670 nm red light on blood glucose levels following glucose ingestion in normal subjects. [1]

Results

Following a glucose challenge, a 15-minute exposure to 670 nm red light substantially decreased blood sugar levels. The peak glucose level decreased by 7.5%.

Conclusion

PBM with 670 nm red light has the ability to decrease blood glucose spikes following meals, which can prevent dangerous fluctuations in blood sugar levels.

Study 2: Low-Level Laser Therapy (LLLT) at 830 nm for Healing Skin Lesions and Neuropathy in Type 2 Diabetes

Objective

To examine the impact of LLLT at 830 nm on skin lesions and peripheral neuropathy in type 2 diabetic patients. [2]

Results

LLLT at 830 nm for 9 minutes per session, in conjunction with exercises, significantly improved skin condition and neuropathy symptoms. Skin color normalized by the 21st day, and clinical manifestations of diabetic neuropathy improved significantly.

Conclusion

LLLT at 830 nm combined with targeted exercises constitutes a good management strategy for resolving skin lesions and neuropathy experienced by individuals with type 2 diabetes.

Choosing the Right Device: Wavelength, Power, and Coverage

Great news if you have decided to apply red light therapy to regulate blood sugar levels and manage your diabetes naturally. Using red light therapy at home is possible with the right equipment. However, it's important to select a high-quality, effective, and safe device. Many products on the market that are not FDA-approved may not emit sufficient red or near-infrared light and may not be safe for home use.

Person using a red light therapy panel

To ensure you're purchasing a safe device, ensure that it emits red light at 633 nm and 660 nm, and near-infrared light at 810 nm and 850 nm, since these wavelengths have been clinically proven to help regulate blood glucose levels. Ensure that the device employs LEDs and has enough power, or irradiance. Check for convenient features such as adjustable intensity and hands-free use.

How Total Spectrum Devices Target Metabolism and Energy Balance

Our Total Spectrum series is a line of high-quality red light therapy equipment. These well-made and durable devices produce the specific wavelengths of red and near-infrared light that are effective in keeping blood sugar levels in check. As they are FDA-approved, there is no need to worry about their safety or efficacy. Their ease of use-portability, adjustability, and hands-free operation-allows for simple and safe use at home.

Best Practices: Session Timing, Frequency, and Safety Tips

When doing red light therapy for blood sugar at home, one should adhere to some simple rules. Optimal outcomes can be obtained by applying red light therapy 3 to 5 days a week, with each treatment lasting 10 to 20 minutes. Keep a close eye on your session duration and maintain consistency. Also, maintain a gap of 6 to 12 inches between the device and your body to prevent overheating. By doing so, and by following your device's official usage guide, you will be able to get the optimal outcomes from red light therapy.

Conclusion: Red Light Therapy as a Supportive Tool for Blood Sugar Management

Red light therapy can be a beneficial, non-pharmacologic aid in blood sugar control, particularly for those with type 2 diabetes. It enhances cellular energy production, increases insulin sensitivity, mitigates inflammation, and promotes blood flow-all aiding in the body's ability to utilize glucose.

Done properly and consistently, red light therapy can even help minimize glucose spikes following meals and promote improved overall glucose regulation. Products such as the Total Spectrum series make it all the more convenient. These clinically effective units are equipped with user-friendly features, making them simple and safe to operate from home.

Someone who is using RLT for insulin resistance which part of the body should the light be focused on and what would be the distance from the light to that area be?
Thanks!

Hi Neal,

Aim the light at large glucose-hungry tissues (abdomen/liver area, glutes, thighs). The pre-set Fat Burn & Weight Loss mode (≈ 2 feet, 20 min) is ideal because it is NIR-dominant and matches most metabolic-health studies.

Most metabolic PBM studies irradiate the abdomen (liver/pancreas area) and large skeletal-muscle groups because these tissues dominate glucose uptake. NIR light over the abdomen or thighs improved insulin signalling and lowered blood glucose in pre-clinical and early clinical work.
