What are the benefits of cold packs?

Can Ice packs help you lose belly fat?

Which is better for skin, ice or instant cold?
But, while instant cold or gel packs are easy to store and are more convenient than ice, experts urge caution when applying chemical cold packs because the below-freezing temperature and direct exposure to the skin can cause tissue damage. Because ice doesn’t get as cold, it is safer, and thus preferable to cold or gel packs.
