Anesthesia

Anesthesia is a way of making you fall asleep during a medical procedure like surgery. It's like a medicine that puts you in a deep sleep so you don't feel anything and won't remember what happens during the procedure. Doctors give you the anesthesia through a needle or with special medicines that you breathe through a mask. Once you're under anesthesia, the doctor can do the medical procedure without you feeling any pain.
