The Healing Madness of Sea Swimming by Dr Mark Harper

When his local pool was closed, a friend suggested to Dr. Mark Harper that he try swimming in the chilly sea off Brighton (UK). 13 years on, and Harper dives in, year round, even on Christmas Day (without a wetsuit!). His pioneering research suggests ‘cold water adaptation’ helps you stay healthy and happy. Incredibly, a regular dip could help fight conditions like common colds, diabetes, chronic stress, and even depression.
