Research has shown that red light therapy can help with diabetes by lowering blood sugar levels. [사진=게티이미지뱅크]Research findings have shown that red light therapy, which uses red light, can help manage blood sugar levels.
A study from City University London, UK, recently published in the Journal of Biophotonics, found that red light therapy lowered blood sugar levels in healthy participants. Although the study was not conducted on diabetic patients, researchers believe the therapy could also be useful for diabetic patients as it helps manage blood sugar levels.
15 minutes of exposure to red light reduces blood sugar levels
The researchers divided 30 healthy adults without diabetes into two groups and had them all drink sugar water containing 75 g of sugar dissolved in 150 ml of water. One group received treatment with red light with a wavelength of 670 nm for 15 minutes and 45 minutes before drinking water. sugar water. After recording their blood sugar levels every 15 minutes for the next two hours, the red light group showed 27.7 percent lower blood sugar levels and 7.5 percent lower peak blood sugar levels. % compared to the control group.
The researchers said that although the experiment was conducted on healthy adults, the study results showed the possibility that red light can prevent a rapid increase in blood sugar levels after a meal even in diabetic patients. The explanation is that the decrease in blood sugar levels after exposure to red light is due to the fact that it stimulates the mitochondria to increase energy production. Since glucose is needed for energy production in the mitochondria, blood sugar levels can be lowered by using rapidly rising glucose. Mitochondria are parts outside the cell nucleus and act as power plants that provide energy to the cell.
Dr. Michael Pouner, who participated in the study, said in an interview with the health media ‘MedicalNewsToday’: “It is clear that light affects mitochondrial function and that this causes changes in our body on a cellular and physiological level.” According to this study, exposure to red light just once for 15 minutes can lower blood sugar levels after a meal,” he explained.
The use of LEDs increases rapidly, red light becomes more important
Red light therapy refers to exposing specific areas of the body to low-wavelength red light or near-infrared light using a laser or other device. It is primarily used in skin treatment to improve wrinkles, age spots and scars, and in recent years, a growing number of researchers are focusing on red light as a potential treatment for other diseases.
Recently, with the rapid increase in the use of computers and smartphones and the increase in the number of people exposed to LEDs, the importance of red light is growing. In sunlight, red and blue light coexist in balance, but the LEDs used in smartphone screens, cars, televisions, etc. contain mainly blue light. According to previous research, prolonged exposure to blue light weakens the function of mitochondria that respond to red light, reducing energy production and increasing the risk of developing certain cancers such as breast cancer and type 2 diabetes.
Small-scale research has limitations, but new efforts are positive.
However, some point out that this is a small-scale study and that it is difficult to accept the results as they are. “Further research is needed to determine whether patients with abnormalities in glucose metabolism are affected by red light and whether the same results are obtained when the number of participants increases,” said Jennifer Cheng, director of endocrinology at an academic medical center in New Jersey. “In this case there is the problem that many variables that can influence the results, such as body mass index and fat mass, were not considered,” she pointed out.
Furthermore, he said that so far outdoor activities have been recommended to help diabetic patients continue to exercise, but if it is proven that outdoor activities are beneficial on other levels, other ways will be found to help diabetic patients , and it’s important to keep trying new approaches.evaluated.
In 2021, the number of diabetes patients worldwide is approximately 537 million, which is expected to increase to 643 million in 2030 and 783 million in 2045. Approximately 90-95% of diabetes patients suffer from type 2 diabetes Unlike type 1, which is an autoimmune disease, type 2 diabetes can be managed and alleviated through blood sugar management medications and lifestyle changes.
