Ergonomic design: the ergonomically designed 360° all-round migraine ice head wrap covers the forehead, temples and eye sockets that are often affected by migraines. It provides moderate pressure, is comfortable fitting and not stiff, while promoting deep relaxation and improving sleep quality. Adjustable and adaptability: the migraine relief cap is suitable for men and women of all ages as well as for all head sizes. It is versatile and offers ideal results, whether for relieving headaches at work or relaxing at home. Natural pain relief method: physical cold therapy shrinks the blood vessels of the head due to cold, slows nerve conduction, relieves your muscle tension and relieves your pain. It can effectively relieve migraines, stress, inflammation, sinusitis, eye bags, tension and pain caused by wisdom teeth. Good sleeping environment: the design of the headache cooling mask effectively blocks light and reduces noise to create a quiet and relaxing environment to rest. In addition, the unique cooling technology regulates the temperature around the head, provides long-lasting cooling and relieves pain. Hot and cold therapy: the migraine relief mask offers a double application with heating and cooling therapy, as needed. For cold therapy, put it in the fridge for at least 2 hours. For heat therapy, heat it in the microwave for 40 seconds (adjust the heating time depending on the microwave power).
