5. Healthy Hair and Nails
The integumentary system (which includes hair and nails) is often the first place that a serious vitamin deficiency shows up. This shortage can cause weak, deformed fingernails and toenails and hair that falls out in clumps. If your hair’s biggest problems are frizziness or split ends, then it’s more or less healthy.
6. Regular Menstrual Periods
Regular periods with normal premenstrual symptoms are one of the best indicators that your reproductive system is healthy. Irregular, painful periods and excessive or prolonged bleeding are symptoms that should be checked out by a doctor.
7. Decent Sleep
True, most of us don’t get quite as much sleep as we should, and occasional insomnia is considered normal. But as long as you’re sleeping through the night on a regular basis and not experiencing night sweats or being awakened repeatedly by the urge to urinate, you’re probably hitting all the necessary sleep rhythms. And if you’re generally waking up feeling at least moderately refreshed, things are looking good.
It should go without saying that the absence of these signs can mean hundreds of different things and can signify dozens of different problems—or sometimes nothing at all—and a doctor is the only one who can say for sure. And that means a real doctor—because sometimes WebMD just doesn’t cut it.
