Placebo Analgesia

Placebo analgesia is the reduction of pain experienced after receiving a treatment that has no active medical ingredients, simply because the person believes it will help. This effect occurs because the brain can release natural pain-relieving chemicals, like endorphins, in response to the belief or expectation of relief. Essentially, the mind's expectation triggers a real physical change, leading to pain reduction even though the treatment itself is inert. Placebo analgesia highlights the powerful connection between psychological factors and the perception of pain, emphasizing how expectations can influence physical sensations.
