Sleep Aid This device can help you fall asleep and alleviate anxiety and depression, making it suitable for individuals experiencing insomnia and anxiety. Microcurrent Stimulation Gently holding the sleep aid device allows microcurrents to be transmitted to the brain through the Laogong acupoints in the palm. This process produces a calming and relaxing effect, promoting healthy sleep. Portable & USB Charging Design The mini, handheld sleep device is lightweight and easy to carry. It features a USB charging design with multiple power supply options, ensuring easy and convenient charging and long battery life. The sleep aid instrument is made of ABS material, providing stability, firmness, and durability. It is available in multiple colors, allowing you to choose according to your preferences. How to Use: 1. Select either sleep aid mode (relax) or excitement mode (active) at the bottom of the device. 2. Place the protruding electrode against the palm of your hand, ensuring your palm touches the electrode's edge to form a microcurrent loop. 3. Turn the side knob to gradually adjust to a comfortable setting.
