Cold Therapy Explained

In brief: Cold therapy, sometimes called cryotherapy in its broadest sense, is the use of cold to manage soreness, swelling and recovery. For runners it ranges from a simple ice pack on a sore spot to cold water immersion and specialised cold chambers. Cold is widely used to ease the feeling of soreness after exercise and to settle minor aches, though it should be applied carefully to protect the skin.

What is cold therapy?

Cold therapy is an umbrella term for using cold to influence how the body feels and recovers. It covers everyday measures such as an ice pack or cold compress on a specific area, broader methods such as cold water immersion and ice baths, and dedicated facilities such as whole-body cold chambers. The common thread is lowering the temperature of the tissue for a period of time.

How it works

Applying cold narrows local blood vessels and slows activity in the tissue, which can reduce the sensation of pain and help limit swelling in a freshly aggravated area. Once the cold is removed and the area rewarms, blood flow returns. The numbing, soothing effect is why cold is a long-standing first response to minor knocks, strains and general post-exercise soreness.

Why runners use it

Runners use cold therapy to take the sting out of muscle soreness after hard efforts, to settle a minor ache or freshly tweaked area, and simply because cold legs often feel refreshed. It is accessible, since a bag of ice or a cold pack is all that is needed for the simplest version, and it can be targeted precisely at the spot that needs it.

How to use it

For a targeted area, wrap an ice pack or cold compress in a thin cloth rather than placing it directly on bare skin, and apply for roughly fifteen to twenty minutes at a time with breaks in between. Never leave cold on long enough to risk an ice burn or numb, pale skin. For immersion or whole-body cold, follow the safety guidance for those methods. Persistent or severe pain should be assessed by a clinician rather than simply iced.
