When we work out, we have the best of intentions: to get stronger, lose weight, or simply improve our attitude for the day.
But injuries are still bound to happen, whether from performing moves improperly, overextending ourselves through repetitive use of certain muscles, or falling and straining a muscle.
So should you use heat or cold therapy to treat your injury?
Below I’m breaking down the difference between new and old injuries and what to do to recover from each—so you can get back to your workouts pain-free.
When To Use Cold Therapy To Treat Injury
New Injuries (Acute Pain)
For injuries that are less than six weeks old, you’re looking at “acute pain” at this point. Think pulled muscles, twisted ankles or a tweaked back.
For these new injuries, you’ll want to use cold therapy: whether by applying ice, or a cooling gel pack.
- Ice not only numbs the pain but will decrease inflammation and swelling.
- You do not want to use heat to treat acute injuries, because it can increase inflammation, which will delay your healing.
When To Use Heat Therapy To Treat Injury
Old Injuries (Chronic Pain)
For injuries that are more than 6 weeks old and still hurt, you’re dealing with chronic pain. For these types of injuries—or arthritis—you’ll want to use heat.
In addition, tight, achy muscles and joints react well to heat. I personally use heat on my low back regularly in the morning to improve mobility.
- Heat works best for chronic pain because it increases blood flow and helps relax and soothe those tight or painful joints.
- It’s best to apply heat before a workout if you have chronic pain, not after, as that can be more aggravating to your muscles.
