A new study conducted by scientists from City College London, University of London, and University College London shows that shining 670 nanometers of red light on a person's back for 15 minutes can lower blood sugar levels. The reason is that this red light stimulates energy production within the mitochondria of the human body, increases glucose consumption, and thus lowers blood sugar levels. The data shows that red light stimulation reduces blood glucose levels by 27.7% after glucose intake, and reduces the maximum glucose peak by 7.5%. The relevant paper was published in the latest issue of the Journal of Biophotonics. To explore the effect of 670 nanometer red light on blood sugar, researchers recruited 30 healthy participants and randomly divided them into two groups. There are 15 people in the 670 nanometer red light group and 15 people in the placebo (no light) group. These participants had normal metabolism and did not take medication. Subsequently, the researchers had participants undergo an oral glucose tolerance test and record their blood glucose levels every 15 minutes for the next two hours. The results showed that people who received 15 minutes of red light showed a decrease in peak blood glucose levels and a decrease in total blood glucose within two hours. The researchers said that although the latest research was conducted on healthy people, this non-invasive and non drug technology can help diabetes patients better control blood sugar. In addition, this study also emphasizes the long-term effects of light on human health, including the possibility of blood glucose imbalance caused by prolonged exposure to blue light. The widely used LED lights emit blue light, which may be a potential public health issue. Previous studies have confirmed that long wavelength light (from visible to near-infrared range) between approximately 650 and 900 nanometers can increase the production of adenosine triphosphate in mitochondria, lower blood sugar, and improve animal health and lifespan. Previous studies also showed that the back of mice irradiated with 670 nm light could also improve the symptoms of Parkinson's disease model and diabetes retinopathy model in mice. (Lai Xin She)
