A state of the mind called hyper-arousal is very common, particularly among smarter people. Smartness comes at a tradeoff. There is increased sensitivity to noise, smells, textures, emotions, and often an inability to loosen up, relax and let go. The last one is what often makes people miserable keeping them from getting adequate restful sleep. Sleep, which is required to do the body's housekeeping work. Imagine a house that has not been adequately cleaned, dishes not washed and laundry not done, week after week, month after month, and year after year. The treatment is in training your mind to do what does not come naturally to it.
