Shanglaite's beauty devices designed for fatigue relief combine various technologies to target the root causes of tiredness and rejuvenate the body. One key approach is through enhancing blood circulation. Devices that incorporate heat therapy, such as full - body panel biotherapy devices with adjustable temperature settings, warm the body, causing blood vessels to dilate. As a result, blood flows more freely, delivering oxygen and nutrients to cells more efficiently and removing metabolic waste products, which helps reduce the feeling of fatigue. Light therapy also plays a significant role. Red and near - infrared light can penetrate the skin and interact with the mitochondria in cells, the powerhouses responsible for energy production. By stimulating mitochondrial function, these lights increase the production of adenosine triphosphate (ATP), the body's primary energy source, effectively boosting energy levels. Some beauty devices may use electrical stimulation, like microcurrents. Microcurrents mimic the body's natural electrical signals and can stimulate nerve function and muscle contractions, promoting relaxation and reducing muscle tension. This relaxation response helps counteract the physical and mental stress that often contributes to fatigue. Additionally, certain beauty devices can be used in combination with relaxation techniques, such as guided breathing or meditation, further enhancing the body's relaxation and reducing stress - induced fatigue.
