Benumbed refers to a state of extreme numbness or inability to feel sensation, often as the result of cold or shock. The antonyms for "be-numb" are words that indicate the opposite state or condition. These may include words such as lively, animated, vibrant, sensitive, responsive, alert, and awake. These words are often used to describe people who are full of energy and vitality, who are able to react quickly and effectively to their surroundings. In contrast to being benumbed, these opposing states suggest being fully engaged and present in the moment, ready and willing to respond to whatever may come.
