Thank you for your question! These EMS gloves are designed to help relieve hand stiffness, muscle tension, and general joint discomfort, including some arthritis-related symptoms. However, they are **not specifically designed to treat Raynaud's disease**. Since your daughter has severe Raynaud's, we recommend consulting her doctor before using the gloves, especially if she experiences poor circulation, numbness, or painful episodes. Her safety is our priority, and we want to ensure the device is suitable for her condition.
