5.1Why are you always tired？💤

Of course your mental well-being plays a role too. Anxiety is a big one. Worrying what people think, always feeling tense about work, or being overly concerned about every decision can be physically exhausting. And fatigue is one of the main symptoms of generalized anxiety disorder. Not only that, but anxiety may be affecting your sleep quality. On another serious end, depression can cause both physical and emotional fatigue, which more sleep won’t necessarily relieve. For some, it causes insomnia or the inability to fall asleep in the first place. Unfortunately there’s no quick fix for the 10% of Americans who do suffer from depression. So if you think you may be depressed, see your physician or psychologist. 当然你的精神状态也会产生一定作用。焦虑就是一个大的因素。担忧他人的想法，总是因为工作感到紧张，或过分担忧每一个决定都会让人身体疲倦。 疲劳是广泛性焦虑症的主要症状之一。不仅如此，焦虑还有可能影响你的睡眠质量。 从另一个严重角度来看，抑郁可以引起生理和情绪两方面的疲劳，再多的睡眠都未必能够缓解。对一些人来说，抑郁首先就会引起失眠症或者入睡困难。 遗憾的是，对于遭受抑郁的10%的美国人来讲，目前没有快速解决办法。所以，如果你认为你有可能身患抑郁症的话，那就去看医生或者心理医生。
