阳光是人们获得维生素d的主要途径。事实上，太阳中的紫外线刺激皮肤产生维生素d。但这还不是全部。
We all know that exposure to a lot of ultraviolet (UV) from the sun can cause skin cancer and premature aging. However, that is no reason to deny the benefits of sunlight. This natural light source not only provides energy, but also offers many important health benefits.
我们都知道暴露在太阳的紫外线下会导致皮肤癌和过早衰老。然而，没有理由否认阳光的好处。这种自然光源不仅提供能量，还提供许多重要的健康益处。

让我们在下面的文章中看看阳光是如何工作的。

Sunlight has the ability to boost the production of serotonin - a chemical transmitter that plays a role in stabilizing mood. Therefore, designing a living space with plenty of natural light will be very good for the homeowner's mental health. In addition, many studies show that serotonin also works to treat depression and anxiety.
阳光有能力促进血清素的产生，血清素是一种化学递质，在稳定情绪中起着重要作用。因此，设计一个有充足自然光的居住空间对房主的心理健康是非常有益的。此外，许多研究表明血清素也能治疗抑郁和焦虑。
