Many of the conversations that are had about sleep and health revolve around problems and disruptions: too much sleep, not enough, how sleep disorders form, and the many ways in which sleeping poorly can affect your health (of course, in a negative way). However, there's another side to the conversation. What does sleeping well say about your body and how it's currently faring? If you sleep like a log every night, you'll likely give no thought to this at all, but it turns out that good sleep can tell us several things about the state of your body, all of which are relevant to your overall health.
Restful, refreshing sleep that lasts eight or nine hours isn't as common as it should be among adults.

If you are among the lucky people who sleep without the need for supplements or sleep aids, don't wake up in the night or experience fatigue in the daytime, and have no real worries about your nighttime functioning, that's an important element of your health. Here's what good sleep can tell you about your body.
