It sounds like the plot of a vampire novel -- an otherwise healthy, well-adjusted person begins to live a life shrouded in darkness. She works nights and sleeps all day behind blackout curtains. If she must leave the house during the day, she slathers on a thick layer of sunscreen and hides behind dark glasses. Yet for those with heliophobia, or fear of sunlight, this may be reality. 

这听起来像一个小说的情节——一个健康的、适应性良好的人的生活开始笼罩在黑暗中。她晚上工作，白天就躲在窗帘后睡觉。如果哪天不得不出门，她则必须要涂上厚厚的防晒霜并戴上墨镜。然而对那些日光恐惧症患者而言，这也许就是现实。 

Heliophobia, or fear of sunlight, is a problem that afflicts tons of of people, however one that suffers from a scarcity of true research. 

日光恐惧症是一个严重折磨患者的疾病，然而目前仍然缺乏对其真正的研究。
