How Cold Should an Ice Pack Be?

Assemble an ice pack to ease muscle pain.

Ideal Temperature

Water freezes at 32 degrees Fahrenheit, so most ice packs will read this temperature. However, according to Baseball Tips, 27 degrees is optimum because it allows for more frozen-time and better tissue penetration. To use a pack that reads a temperature of 27 degrees, purchase a synthetic cold pack that can freeze at a lower temperature than water.

Frostbite Danger

Anything below 27 degrees offers a threat of burning the skin because of the low temperature. To prevent frostbite, do not use a pack that reads a temperature of lower than 27 degrees or hold a cold pack on the skin for a long period of time.

Bottom Line

Ideally, use a pack that reads 27 degrees Fahrenheit. Anything warmer will melt quickly when applied to the skin, and anything colder can burn the skin.
