Sunshine is back in the good books of medical practitioners and dermatologists. New research suggests that fifteen minutes a day of direct exposure to sunshine may be beneficial in the prevention and treatment of many forms of cancer. Researchers point to the fact that there is a lower incidence of prostate, colon and breast cancers in sunnier parts of the world.
Dr. Edward Giovannucci of Harvard University suggests that vitamin D, also known as the “sunshine vitamin”, might help prevent 30 deaths for each one caused by skin cancer. He said: "I would challenge anyone to find an area or nutrient or any factor that has such consistent anti-cancer benefits as vitamin D."
Plastering our bodies in sunscreen to avoid skin cancers, such as melanoma, may be more harmful than direct exposure to the sun. Sunscreen blocks UV rays and therefore inhibits the vital production of vitamin D. Our skin absorbs the rays and produces vitamin D. Melanoma, the deadliest kind of skin cancer, accounts for just 1.4 per cent of all cancer deaths.

医疗从业者和皮肤病医生的书里又开始推荐阳光
。最新研究认为,每天阳光直射15分钟可以预防和治疗许多种癌症 。研究人员指出了一个事实,在世界上阳光照射比较多的地区,前列腺癌,结肠癌和乳腺癌的几率较低 。哈佛大学的Edward Giovannucci表示,维生素D,也叫做“生命维生素”,可以降低皮肤癌造成的死亡率
。他说:“我可以挑战任何人,能不能找到任何一个地区,或者任何一种营养,或者任何一个因素可以像维生素D一样有这么好的功效 。”涂抹防晒霜来预防黑素瘤等皮肤癌可能比阳光直射更有害
。防晒霜会阻挡紫外线,因此会妨碍维生素D的生成 。我们的皮肤吸收紫外线后才会生成维生素D 。最致命的皮肤癌——黑素瘤占所有癌症死亡人数的1.4% 。
