Cold Ears: More Than Just Chills! Doctors Warn of Serious Health Risks

• Ears lack protective fat/muscle, making them vulnerable to cold and rapid body temperature drop.
• Direct cold exposure can cause 'thermal shock', leading to headaches, dizziness, and fatigue, especially for BP patients and elderly.
• Vagus and facial nerves behind ears can be stimulated by cold, causing severe headaches or temporary facial paralysis.
• Cold ears constrict blood vessels, raising blood pressure by 10-15 points and stressing the heart for hypertension patients.
• Body diverts energy to warm ears, weakening immunity and increasing risk of colds, coughs, and viral fevers.

Why It Matters: Covering ears in cold is vital for health, preventing thermal shock, nerve issues, and weakened immunity.
