The Healthify Sugar Regulator Bangle features two types of technology: negative ion and far infrared technology. Both of these technologies work together to help regulate blood sugar levels in the body. Far infrared technology is another key feature of the Healthify Sugar Regulator Bangle. Far infrared rays are a type of electromagnetic radiation that is emitted by the sun and other natural sources. They have been shown to penetrate deep into the body and stimulate the production of nitric oxide, a compound that helps to relax blood vessels and improve blood flow. When the Healthify Sugar Regulator Bangle is worn on the wrist, the far infrared rays penetrate the skin and are absorbed by the body. This helps to stimulate the production of nitric oxide, which can lead to improved blood flow and lower blood sugar levels. The Healthify Sugar Regulator Bangle is infused with negative ions, which are emitted from the bracelet and absorbed by the body through the skin. The negative ions help to improve circulation, which can lead to a reduction in blood sugar levels. Additionally, negative ions can help to regulate insulin secretion and improve insulin sensitivity, which is crucial for maintaining healthy blood sugar levels.
