Massagers are devices designed to relieve muscle tension and promote relaxation. They come in various forms, including handheld models, massage chairs, and foot massagers. Many massagers use techniques like kneading, tapping, or vibration to mimic the effects of a professional massage. These devices can be beneficial for reducing stress, improving circulation, and alleviating pain. Some massagers are specifically designed for targeted areas, such as the back, neck, or feet, while others provide full-body relief. Popular types include Shiatsu massagers, percussive massagers, and electric massagers, each offering unique features and benefits.
