7. Sunshine
日照
For years, health-care authorities have warned us about the sun's damaging effects. But researchers are increasingly finding that sunshine, in moderation, can be beneficial. We know that sunlight prompts our bodies to produce vitamin D, which helps develop and maintain strong, healthy bones. Recent studies indicate that vitamin D also helps prevent colorectal, breast and prostate cancers, as well as autoimmune disorders such as multiple sclerosis and Type 1 diabetes.
多年来，医疗专家都在提醒我们日照的危害。但是，越来越多的研究发现，适量的日照是有好处的。日照可以帮助人体合成维生素D，从而有利于保持、发展健康的骨骼。最近的研究表明，维生素D可以帮助预防结直肠癌、乳腺癌和前列腺癌，还可以预防自身免疫疾病，比如多发性硬化症和I型糖尿病。
