Every day, your body tells you all kinds of things: Scratch my elbow. I’d like some salt. But hidden in these signals can be deeper messages about your health. Here’s how to decode them.

 

What You Can Learn From the Whites of Your Eyes

If they look grayish: It’s probably just a result of the natural aging process, which can make the whites of your eyes (formally known as sclerae) become grayer. “The sclera thins over time, so the deep vascular tissue underneath shows through,” says Christopher Coad, an ophthalmologist at Chelsea Eye Associates, in New York City. That said, there are some serious medical conditions that can turn your whites gray, including rheumatoid arthritis and brittle bone syndrome. As a starting point, schedule an exam with your ophthalmologist, who may refer you to a specialist.

If they look red: Most likely, your eyes are dry. Those red squiggles you see are tiny blood vessels, which become more prominent when eyes are irritated. “Dryness can be a result of age, staring at the computer, or environmental factors, like air-conditioning,” says Coad. Preservative-free artificial tears (sold at drugstores) help lubricate eyes with ingredients like glycerin and can soothe irritation; use four to six times daily, as needed. If the dryness worsens, see your ophthalmologist, as “dry eyes can be a symptom of conditions like thyroid disease and diabetes,” says Coad. If you also have itching and tearing, allergies may be to blame; try an over-the-counter antihistamine.

If they look yellow: It may be jaundice, which is caused by a high level of bilirubin, a by-product of red blood cells. See a doctor right away, as jaundice can be a sign of several serious health problems, including liver dysfunction, hepatitis, and, in rare cases, pancreatic cancer.

 

What You Can Learn From Your Sleep Habits

If you fall asleep as soon as your head hits the pillow: Surprise, surprise—you’re probably sleep deprived, says James Herdegen, M.D., the medical director of the Sleep Science Center at the University of Illinois at Chicago. It takes a well-rested person about 10 to 15 minutes to fall asleep. Ideally, aim for eight hours or so a night. If you already get that much, see your doctor to rule out sleep-onset conditions such as restless legs syndrome.

If you wake up a lot at night: You may have sleep maintenance insomnia, in which the difficulty isn’t falling asleep but staying asleep. The disorder has been linked to anxiety, depression, and sleep apnea. If you toss and turn or experience daytime sleepiness for more than four weeks, see your doctor, who may refer you to a sleep specialist.

Quick Tip

Nuts

Juice may serve up vitamins, but it won’t do much to ease hunger: Unlike solid foods, liquids don’t trip the brain’s satiety mechanism. For a more effective snack, pair a glass of 100 percent juice with a few nuts. Get more tips.
