Is dry ice harmful to the body?

Yes.

According to the Economic Daily, the cooling effect of dry ice is more than 1.5 times that of water ice. When dry ice evaporates, it will cause the surrounding temperature to drop sharply, posing a potential risk of frostbite to the human body. Children, in particular, like to put dry ice on their hands or other parts to cool down or play, which can easily cause frostbite to the skin.

It is unlikely that ice will explode under normal circumstances, but there is still a certain risk of improper storage. When dry ice volatilizes, it will release carbon dioxide gas that is more than 1,000 times larger than solid dry ice. If it is placed in a closed environment, great pressure will be generated inside the storage environment, which will eventually lead to a physical explosion. Extended information
