An anxiety ring is a ball bearing band worn around your finger. It’s a discrete way for many people to reduce anxiety by focussing on spinning or rotating the ball. Wearing one can help to distract you from anxious thoughts or situations, but they’ll only reduce your symptoms on a short-term basis.
Buying an anxiety ring won’t ‘cure’ your anxiety, but alongside further treatment, such as talking therapies, they can help to reduce your symptoms over a longer time.
