anaesthesia
Medically induced insensibility
Anaesthesia is the loss of sensation, especially the medically induced state that allows surgery without pain.
General anaesthesia renders a patient unconscious; local anaesthesia numbs a specific area while the patient remains awake.
The spelling with the "ae" is British; Americans write anesthesia.
Figuratively, emotional anaesthesia suggests numbness to feeling: a protective anaesthesia against grief.
