Hot and cold therapies are simple yet effective methods for managing pain, inflammation, and muscle injuries—but knowing when to use each is key to proper recovery.
Cold therapy (cryotherapy) is best applied within the first 24–48 hours after an injury, such as a sprain, strain, or bruise. It helps reduce swelling, inflammation, and numbs sharp pain by constricting blood vessels. Apply an ice pack wrapped in a towel for 15–20 minutes at a time, several times a day.
Hot therapy (thermotherapy) is ideal for soothing chronic muscle pain, stiffness, or tension. It increases blood flow, relaxes tight muscles, and promotes healing in conditions like arthritis, back pain, or soreness after exercise. Use heating pads, warm compresses, or hot baths for 15–20 minutes, but avoid heat on fresh injuries.
Avoid using heat if swelling is present, and don’t apply cold for too long to prevent skin damage.
