When something hurts, many people wonder whether to reach for a heating pad or an ice pack. The answer depends on the problem.
As a general guide, cold is often used for new injuries and swelling, because it can numb the area and calm swelling. Heat tends to suit stiff, tight muscles and aching joints, since it relaxes tissue and increases blood flow.
- Wrap ice packs and heat sources in a thin cloth, never against bare skin.
- Limit each session to about 15 to 20 minutes, then give your skin a break.
- Do not fall asleep with a heating pad on.
Check with a doctor first if you have diabetes, nerve problems or reduced sensation. See a doctor too if pain follows a significant injury or does not improve.
