维生素 D 与抑郁症(2020)
Vitamin D and Depression (2020)

导读
这篇论文(2020)综述了维生素 D 与抑郁症之间的关系,探讨维生素 D 缺乏是否与抑郁相关、补充维生素 D 能否改善抑郁症状。综合来看,证据并不一致,补充剂对抑郁的疗效尚无定论。
HN 关注点:HN 读者长期关注维生素 D 补充剂、光照与情绪健康的关联,讨论焦点在于:抑郁问题究竟该靠补剂解决,还是靠晒太阳、光照疗法和昼夜节律调节。

补充光照比补维生素 D 更关键,论文遗漏了 SAD 和光照疗法
每天早晚接触明亮的光线,可能比直接补充维生素 D 更有助于减轻抑郁。维生素 D 低可能只是晒太阳不足的一个指标。阳光还会影响褪黑素和血清素水平,并同步你的昼夜节律。不明白这篇文章为什么不谈季节性情感障碍(SAD),以及被公认为有效疗法的光照疗法。

Daily morning and afternoon exposure to bright light might actually be more important to reducing depression than direct vitamin D supplementation. Low vitamin D might just be an indicator that you are not getting enough sunlight. Sunlight also affects melatonin and serotonin levels, and synchronizes your Circadian rhythm. Not sure why that article doesn't talk about Seasonal affective disorder (SAD), and how bright light therapy is considered an effective treatment for it.
亲历亲历:每天晒太阳半小时后抑郁症状消失
我在纽约的第一个冬天非常难熬,起初不明白为什么。医生验血后说我的维生素 D 很低。我坚持每天在阳光下至少散步半小时(天气允许的话),之后基本再没出过问题。部分原因是我虽然常在户外走动,但由于高楼遮挡,其实没晒到太阳。仅是个人经验之谈。

My first winter in NYC was very rough and I didn't understand why at first. I got a blood test at the doc and he said my vitamin D was very low. I committed to walking in the sun at least a half hour a day, weather permitting, and I never really had issues again. Part of the issue was I was spending a lot of time walking outside but not in sunlight due to the tall buildings. Just my anecdotal 2c
亲历亲历:晨间户外劳作带来的益处是药片无法替代的
我是远程工作者。每天早上站会后,只要可以,我都会去大院子里做园艺半小时到一小时。这是一种我会坚决捍卫的乐趣。回到键盘前,我的心态和精力都明显改善,我相信午饭前就能把这段时间的生产力补回来。不知道这多少归功于维生素 D、森林浴,还是运动给神经元供氧。我怀疑一颗药丸替代不了它。

I'm a remote worker. After an early morning standup I go outside and do yardwork in a big yard for a half hour to an hour, whenever I can. This is a pleasure that I've come to defend fiercely. When I sit back down at the keyboard my improved attitude and energy are such that I believe I make up that time in productivity before lunch. Don't know how much of that benefit is from increased vitamin D, from the forest bath, or from the exercise oxygenating my neurons. I doubt I could replace it with a pill.
亲历亲历:去掉遮光帘、随日出自然醒来治好了 SAD
有意思的是,我季节性情感障碍的解法是几年前搬进一间没有百叶窗、早晨阳光充足的公寓(之前住的地方装了遮光帘)。我们一直没装百叶窗,现在也不打算装——如今我自然随日出在早上 6 点左右醒来,SAD 再没犯过。我的看法是,遮光帘通常不利于睡眠卫生(除非你住在特别亮的地方、确有必要),因为它们破坏了一些最自然、最有效的授时因子。不是说懂行的人不能巧妙利用遮光帘打造睡眠环境,但大多数人不会周全地权衡这些因素。

Interestingly the fix to my seasonal affective disorder was a move a couple years ago into an apartment with no blinds and tons of sun in the morning (our previous place had black out blinds). We never got to adding blinds, and we have no intention to at this point—I wake up with sunrise naturally nowadays around 6am and haven’t had SAD since. I’m of the impression that black out blinds are generally poor for sleep hygiene (unless you’re in a really bright place and they’re a necessity), as they disrupt some of the most natural and most potent zeitgebers available. That isn’t to say that a knowledgeable and enterprising person couldn’t employ black out blinds when crafting their sleep environment, but most people won’t balance the different influencing factors thoughtfully.
