A good night's sleep is essential to our physical, mental, and emotional health. Many Americans don't get enough.

Most experts agree, a typical adult should get 7-8 hours of sleep a night. So, what's the best time to go to bed?

That varies, depending on your work schedule.

If you have a "day job," Time.com recommends you be in bed by 10 pm. That allows you get get 7-8 hours of sleep, and be up at 5 or 6 am. If you have to be at work by 8, that's enough time for a cup of coffee, and 30 minutes of exercise before work.

I typically go to bed between 10 and 10:30, getting up between 6 and 7. That gives me time for coffee, and browsing the internet for ideas to share.
