What happens if you ice for more than 20 minutes?
Greater than 20 minutes of icing can cause reactive vasodilation, or widening, of the vessels as the body tries to make sure the tissues get the blood supply they need. Studies have also shown 30 to 40 minutes in between icing sessions are needed to counter this reaction.

Ice should be applied to an acute injury for 10 minutes at a time. Any longer than this could result in tissue damage to the skin by frostbite or lack of blood flow.
Are gel packs better than ice?
Gel ice packs actually warm up faster than regular ice. Heat can travel more easily through the liquid so the ice pack gets warm faster. So if you’re looking for something that will stay cold longer you’re much better off freezing a water bottle or using regular ice than using an ice pack.

How does instant ice pack work?
