Reflex actions are automatic and do not involve thinking.
Why is this an advantage?

You don't have to think about it because the response is a reflex that does not involve the brain. A reflex is a rapid, unlearned, involuntary response to a stimulus. Reflexes are responses that protect the body from potentially harmful events that require immediate action.
