Summarize this article:

Pick your snake up by the middle of the body and support it with both hands. When holding your snake, hold it away from your face. Pet it in the way the scales go; they don't like it the other way around.  Do not handle a snake after it’s eaten for 48 hours. Wash your hands after handling your snake. When your snake’s eyes glass over it’s time for it to shed. Your snake should not be handled at this stage; as they may resort to self-defense, wait until after the shed.  Corn snakes do not require misting or a humid hide to have a good shed. However, if they get stuck shed or they don’t shed in one piece it’s best to mist and provide a humid hide then. After a few days, your snake's eyes will return to normal and a few days after that the shed will happen. You may want to measure and laminate the shed as a record.

Summary:
Handle your snake with care. Know when snakes shed.
