Cold Compresses vs. Hot Compresses – What’s the difference?

Hot and cold compresses are both common physical therapy methods. Sometimes, people can use both methods to relieve pain from minor injuries they suffer in their daily lives.

How do cold compresses work:

Ice packs (you could also use ice cubes or iced bottled water) are practical items for emergency trauma treatment – that’s why many people keep them at home.

The decrease in temperature causes vasoconstriction. After a sprain or contusion, swelling occurs due to the rupture of small blood vessels and the infiltration of blood into the surrounding tissues, and the swelling compresses nerve endings and brings pain. The cold compress causes vasoconstriction to interrupt this pathological process. When the cold compress is stopped and the blood returns to normal, the damaged part of the body has been repaired and coagulation has been produced, thus reducing local bruising and swelling. Hot compresses are then applied to promote the absorption of bruising, which is the best treatment for sprains.

When people have a fever, if antipyretics don’t work, cold compresses can be applied (on the head, neck, armpits, root of thighs, and other areas with large blood vessels).

Note: You need to take proper care when applying ice to avoid frostbite to the skin.
