Here is another amazing and interesting fact for you by planet4facts
You probably think that only hot objects, such as a lighted match, can burn you. When you touch something hot, the nerve-endings in your fingers react at once.
The nerve instantly flashes a message to the brain, telling it that something dangerous is happening to your fingers. The brain returns the warning message to your finger causing them to move sharply away from the hot object.
The truth is that you can also ‘burn’ your fingers by holding a block of ice for too long. The ice rapidly removes body heat away from your fingers, which produces a burning sensation felt as pain. The sudden loss of heat has damaged the sensitive nerve-ending resulting in an injury similar to one caused by fire. Dry ice, which is solid carbon dioxide, can cause severe burns.
