On a typical day my alarm goes off at or around 6:30 a.m and I am in bed around 11:00 p.m. In between that time I am exercising, working, running errands, making dinner, making plans, doing laundry...the list is endless. And my weekends are not really filled with days of sleeping in, even if I am beyond exhausted. 
I recently read an article that said: "young women have accepted exhaustion as a normal state of being." Last year, the CDC proclaimed insufficient sleep a public health epidemic. Even more concerning...an American Psychological Association survey showed a large gap between the level of stress people say they experience and what they think is healthy.
Many of us don't even realize how tired we are. With serious fatigue comes a continuous rush of the stress hormone cortisol, which can act as a mental and physical stimulant. And your brain rewards you for that big score at work, releasing feel good chemicals. So highly charged people don't sense that they are burning out.
So how do you go from ragged to rejuvenated?
By now, I have identified my warning signs: bitchiness, uncontrollably laughing that turns into crying, inability to focus. This usually means it's time to get in bed earlier and give up one of my activities (usually exercising) until my body feels like it can work at full steam.
I'd also really like to bring naps back...just saying.
