Stress Relief Bands are the groundbreaking wearable devices that use synchronized vibrations to reduce stress and anxiety by over 70% in as little as 30 seconds. Wear them on your wrists, put them in your pants pockets or hold them in your hands. The alternating vibrations shift your brain from the "fight or flight" mode to the "calm and logical" parasympathetic mode to help you relax, improve your sleep and increase your focus. Use them 10 to 20 minutes in the morning or at night, or during the day as needed. Available in S (wrist circumference 5.5"-6.7") or L (6.7"-8.1"). Stress Relief Bands (Set of 2) - S
