Explaining how and why we should get sunlight back into our lives - safely - this book shows how sunlight was used to prevent and cure diseases in the past, and how it can heal and help us in the future. Over the last 40 years, there has been a complete reversal in medical thinking on sunlight. Sunbathing is regarded by the experts to be a dangerous pastime which should be actively discouraged, yet little more than 50 years ago doctors in Europe and North America were using sunlight to treat potentially fatal diseases on a routine basis, and a number of hospitals were built specifically for sunlight treatment. The human race evolved under the sun and for thousands of years lived in close harmony with its heat and light. Many of us have lost this close contact with the sun and its healing powers.
