Many of us have heard of hot and cold compress (or hot and cold therapy) to treat various injuries and ailments. However most do not know the difference in terms of specific purpose of each treatment. Hot and cold compress both work differently and each has its own function in terms of treatments.
Hot compress therapy helps to improve blood circulation by dilating the blood vessels in the area where the heat is applied. This brings nutrients to the affected area, thereby accelerating the healing process and reducing pain. It is generally used to release muscle stiffness or soreness, and warm up muscles before you commence physical activity.
How long should you apply hot compress?
Hot compress should be applied to the affected area for about 10 to 15 minutes, between 4 to 6 times a day. Although heat therapy is helpful in relieving pain, please be mindful not to apply it for more than 20 minutes or you run the risk of burning yourself. Also, avoid applying the heat directly on the skin. Try to us a piece of cloth to protect your skin while applying the heat over it. Of course, like everything else, common sense prevails here. If the heat becomes unbearably hot, please remove the heat source to avoid scalding yourself.
