Dr Mark Harper is a consultant anaesthetist at Brighton and Sussex University Hospitals who, accidentally and via quite unrelated routes, has developed an interest in the negative effects of getting cold during surgical operations and the positive effects of cold water swimming. He therefore spends much of his professional life researching ways to keep patients warm and his personal life enjoying swimming in a cold sea.
Mark is the OSS's Cold Expert, and answers members' questions in this section of the website. See the items below for detailed answers on a range of cold water-related topics. Please email your questions to email@example.com
