YOU see them every single day, but when’s the last time you really looked at your hands? If it’s been a while, you may want to start studying. Everything from raggedy nails to shaky digits could signal there’s something up with your health.

    Shaking

    If your hands are shaking uncontrollably, first, don’t panic. One simple explanation for hand tremors can be that you’ve had too much caffeine. And some medications, including asthma drugs and antidepressants, can also prompt your hands to tremble. However, if none of these causes are to blame, or you develop unexplained tremors that occur frequently, see your doctor. A more rare cause could be Parkinson’s disease, a disorder of the nervous system that affects movement.

    Cracked or weak nails

    If your nails seem more delicate than a fancy wine glass, you may have a zinc deficiency. According to Bank, zinc may help with the growth and renewal of skin cells. Consider adding zinc-rich foods to your diet to see if that prompts improvement. Some options: wheat germ, oats, nuts, and meat.

    Peeling and flaky skin

    If the skin on your fingertips is suddenly flaky, you may have a vitamin B deficiency. B vitamins such as niacin (B3) and biotin (vitamin B7) are extra important for healthy skin. Taking a biotin supplement helps to promote healthy skin and nail growth; niacin helps protect and repair skin by preventing the formation of melanin, boosting collagen growth, and improving your skin’s natural moisture barrier. In addition to taking a supplement, add niacin-rich foods such as fish, peanuts, and mushrooms, and biotin-rich foods such as avocados and tuna, to your diet.

    Pale or white nail beds

    This type of discoloration can be a sign of anemia, which means you’re not making enough healthy red blood cells to carry adequate oxygen to your tissues. A routine blood test can check for anemia, and treatment generally consists of iron supplementation — but requires an appropriate medical evaluation first.

    Dryness, itchiness, and rash

    If it feels like no lotion is ever a match for your rough hands, you may have eczema, a skin condition that makes skin itchy, dry, or break out in rashes. Speak to your physician and see if you might need a prescription-strength ointment or cream to help restore your skin. If your doc determines that you don’t have eczema and that your hands are simply dry, use rich moisturizers that contain vitamin A. Also apply vitamin E to cuticles at night. Because we don’t wash our hands while we sleep, these products will have a good amount of time to penetrate into your skin.

    Flexible nails

    Nails that are soft and bendable can indicate a calcium or protein deficiency. One of the signs of hypocalcemia — low calcium — can be brittle nails or dry scaly skin and coarse hair. Protein deficiencies can present as nail ridges as well. Be sure you eat a diet rich in dairy products as well as sardines and spinach. If that doesn’t help, see your doc.

    Brown spots

    These are age and liver spots, which are directly caused by sun exposure. Hands are extra-prone to sun damage since they absorb additional UV-rays from their position on the steering wheel when you’re driving. So be sure to slather a high SPF on your hands when you know you’ll be exposed to direct sunlight for extended periods of time. (SD-Agencies)
