This book by Andreas Moritz provides scientific evidence that sunlight is essential for good health, and that a lack of sun exposure can be held responsible for many of today’s diseases. Most people now believe that the sun is the main culprit for causing skin cancer, certain cataracts leading to blindness, and aging. Only those who take the risk of exposing themselves to the sunlight, find that the sun makes them feel and look better, provided they don’t use sunscreens or burn their skin.The UV-rays in sunlight actually stimulate the thyroid gland to increase hormone production, which in turn increases the body’s basal metabolic rate. This assists both in weight loss and improved muscle development. It has been known for several decades that those living mostly in the outdoors, at high altitudes, or near the equator, have the lowest incidence of skin cancers.In addition, studies revealed that exposing patients to controlled amounts of sunlight dramatically lowered elevated blood pressure (up to 40 mm Hg drop), decreased cholesterol in the blood stream, lowered abnormally high blood sugars among diabetics, and increased the number of white blood cells which we need to help resist disease. Patients suffering from gout, rheumatoid arthritis, colitis, arteriosclerosis, anemia, cystitis, eczema, acne, psoriasis, herpes, lupus, sciatica, kidney problems, asthma, as well as burns, have all shown to receive great benefit from the healing rays of the sun.
