Key benefits Supports the body's natural healing processes by delivering terahertz energy to targeted areas, enabling energy absorption, heating, and activation of dormant cells to promote metabolic activity. Three level temperature control with an intelligent poweroff feature for safe, comfortable use. Terahertz Therapy Device can help with sleep quality, circulation, fatigue reduction, metabolism support, and may improve lung function and overall disease resistance. Direct light energy delivery aids absorption, relaxes muscles, improves internal circulation, helps with toxin elimination, and supports better physical function and stress reduction. How it works The device penetrates normal tissues to reach comfortable target areas. Abnormal cells absorb the excess energy and heat, accelerating metabolic processes while activating dormant cells to enhance the body's natural healing response. Core features Terahertz therapy with a threelevel temperature control via a rotary switch, allowing you to choose the desired intensity. Safe operation with an intelligent poweroff function to provide peace of mind during use. Direct light energy delivery into the body to stimulate absorption, relax muscles, improve circulation, aid toxin elimination, and support overall physical performance. Practical applications Sleep support: use in the evening to help improve sleep quality and relaxation. Recovery and fatigue relief: apply after activity to promote circulation, reduce tiredness, and support metabolic processes. Wellness maintenance: integrate into a routine to enhance lung function, resilience to stress, and general wellbeing through improved circulation and tissue energy. Product consistency This description preserves the model focus on the Terahertz Therapy Device, its working principle, temperature control, safety features, and the listed health benefits and use cases without adding or omitting functional details.
