“Stop being a wimp! Pain IS good for you,” reports the Daily Mail today. The paper goes on to say that pain plays “a crucial role in keeping us alive”.
The coverage is based on the results of a study performed in mice, with some preliminary experiments performed in humans. The study explored the effects of “substance P”, which is a chemical released by nerves in response to injury, or chemical or heat pain. The researchers looked at whether “substance P” played a role in tissue healing after a temporary block of blood flow. Blocking blood flow was used to mimic a blood clot or heart attack.
