Health In 2003, Dr. Howard J. Bennett coined the term "Hogwarts headache" in a letter to the New England Journal of Medicine shortly after the release of the longest book in the series, Order of the Phoenix. He described it as a mild condition, a tension headache possibly accompanied by neck or wrist pains, caused by unhealthily long reading sessions of Harry Potter. The symptoms resolved themselves within days of finishing the book. His prescription of taking reading breaks was rejected by two of the patients on which he discovered this headache. Researchers at John Radcliffe Hospital in Oxford found in 2005 that the admission rate of children with traumatic injuries to the city's ERs plummeted on the publication weekends of both Order of the Phoenix and Half-Blood Prince. This was due to the volume of children reading Harry Potter rather than engaging in riskier outdoor activities, such as riding of bicycles and scooters, climbing trees or playing sports. The study was led by Dr. Stephen Gwilym whose paper "hypothesized that there is a place for a committee of safety-conscious, talented writers who could produce high quality books for the purpose of injury prevention," noting a potential problem with this strategy: "Obviously, if children are always in reading books and not outside getting exercise, there is a long-term risk of obesity, rickets and lack of sunlight."
