Are gel packs better than ice?

With most injuries involving the back, gel packs are easy to use. Ice bags are better for ankles and knees for a longer cold period. … Weaknesses: These do not stay cold as long as ice packs, but cold gel packs will cool the skin faster than ice bags and so deserve greater caution.

Why does ice melt more slowly in salt water?

But salt water is much denser than tap water, warm or cold. … Instead, the dense salt water stays at the bottom of the glass and the cold water stays on the top. Without any convection currents to carry the cold water away from the ice cube, the ice cube melts much more slowly.
