It hasn’t been until relatively recently that people are learning how crucial sleep is to improving overall health and wellness — hence, the explosion of the sleep coach industry, reports Men’s Health.

Fortunately, I’ve always considered myself to be a pretty good sleeper. I (almost) always log a solid eight to nine hours, and I hardly ever have trouble falling asleep. But I have my share of can’t-turn-my-brain-off-nights. Plus, my husband works late afternoon to late evening, and since I work early in the morning till late afternoon, I’d love to have the energy to spend more time with him when he comes home.

So I called up W. Christopher Winter, M.D., author of The Sleep Solutionand sleep advisor, to see how my sleep habits impacted my lifestyle — and where I could afford to make some serious changes.
