Doctors prescribe surfing lessons in 'world first' in French seaside town

• 20 doctors are taking part in a pilot scheme
• The doctors are authorised to prescribe a 12-week course in sports, including surfing or paddleboard but also more classic activities like swimming or Nordic walking
• Doctors say surfing and other sports can be highly effective in fighting chronic pain and depression, as well as diabetes and obesity, and helps reduce the 46,000 deaths annually linked to inactivity.

Note that every health problem has been previously associated with low vitamin D (and lack of being outdoors)

Note that the outdoor benefit of vitamin D would only result during summer near noon and if now wear a wetsuit
