Walking in direct sunlight without sunscreen can be dangerous for the skin. However, our bodies also need to catch some rays to maintain health.

Our bodies can't produce vitamin D without direct sunlight. Vitamin D is a crucial chemical for our bones, muscles and immune system. Low levels of vitamin D have been associated with a number of diseases, including dementia, diabetes and autoimmune diseases.

如果没有阳光照射,人体就不能合成维生素 D。维生素 D 是一种维持骨骼、肌肉和免疫系统健康的关键化学物质之一。维生素 D 水平过低与多种疾病有关,包括痴呆症、糖尿病和自身免疫性疾病。

One of the best approaches for increasing vitamin D production is sitting in the sun for short periods and exposing the skin on our forearms, lower legs, or face.

促进维生素 D 合成的最佳方式之一是在阳光下短坐片刻,让前臂、小腿或面部的皮肤接触阳光。
