If the eyes are the windows to the soul, the nails are the door to your overall health. Most of us glance down at our nails and think “I need a manicure” or “I should stop biting my nails” and then forget about it, only to start paying attention when there’s a more serious issue.
However, contrary to popular belief, our nails are usually healthier than we think:
Healthy nails are not just the product of a good manicure, but of good nutrition and overall health.
Whether you’re constantly getting nail art done, or hardly give your nails a second thought, it’s always good to know what healthy nails look like and what potential issues to watch out for whenever they are not, before it becomes pressing.
Brittle, dark, or curved nails may be signs of significant internal health issues.
The body is constantly speaking to us and nails just like skin and hair, can carry serious messages from internal organs that need attention, nutritional needs, and even our emotional state. Anything from poor diet to kidney damage to unhealthy liver function may cause nail damage (or nail trauma) in healthy nail beds.
What we eat, use and feel may show up in our nails.
When the body requires a specific nutrient, vitamin or mineral -or is having too much of them- it immediately sends out signals for course correction. This is also true for chemicals (hello gel nails!) and topical lotions we may be exposed to.
We put together a handy list of healthy nail symptoms and signs, and unhealthy ones, for you to reference back to whenever you feel something is off.
Fingernails are part of the body’s integumentary system. That may be the first time (in a long time) that you hear about that. The integumentary system is formed by the skin, hair, nails, glands, and nerves that act as a barrier to protect you against infections, foreign bodies, and more.
The integumentary system protects the body against disease and helps regulate its functions.
In coordination with the nervous system, the immune system, the digestive tract, and the circulation system, the integumentary system:
This is why fingernails can provide such powerful insight into the body’s overall health, they are connected to everything and can quickly sound the alarm when an issue is starting to pop up.
Nails are produced by living skin cells in the finger made out of mostly keratin, a hardened protein that is also available in the skin’s top layer and in hair. They grow from “the matrix” (and have nothing to do with Neo) where older cells are pushed out, compacted and hardened, eventually becoming the familiar flattened nail at the top of your finger.
Nails are comprised of:
So now that you know what healthy nails look like, how they are formed and how they are connected to your health, let’s look at some common health issues and how they show up on your fingertips:
Usually a product of nail plate dryness caused by chemical exposure, fungus, or malnutrition. Nail polish remover, dishwasher, swimming in pools, cleaning supplies may lead to brittle clear nails.
Possible health problem: healthy nails bounce back easily from chemical exposure if your nails continue to break easily, be very dry, clear, or thin you may have hypothyroidism, psoriasis, or fungal infection. Talk to a doctor.
When the tips of the fingers are enlarged and curved, and the nails have curved around the fingertip over the course of years, the nail is considered clubbed.
Possible health problem: low oxygen in the blood, potential lung disease, inflammatory bowel disease, cardiovascular disease, and unhealthy liver function. Visit a dermatologist or doctor for a diagnosis.
Beyond being an unpleasant sight, chewed nails tend to be a sign of emotional distress and can lead to infections, as the nail debilitates over time and fails the integumentary system.
Possible health problem: anxiety, stress, obsessive-compulsive disorder (OCD,) try relaxing, practicing meditation, and promoting nail growth with supplements, diet, and a coat of poor-tasting varnish.
Black or dark discoloration of the nail may be a sign of blood trauma in healthy nail beds, allergies, or something worse. Seek immediate attention.
Possible health problem: allergic reactions, melanoma. Consult with your doctor immediately.
With the look of an indented line across the horizontal meridian of the nail, these horizontal ridges may be caused by direct nail trauma (from stubbing a toe) or from more serious health issues. They tend to occur when the body is too busy fighting an issue to make new nails.
Possible health problem: serious physical stress, severe malnourishment or nutrient deficiency, or after chemotherapy.
Nails can turn very pale when there are nutritional deficiencies, and they can usually be remedied with supplements, conscious eating, and consistent changes.
Possible health problem: malnutrition, iron deficiency anemia, liver disease, congestive heart failure.
When the nail resembles a spoon with raised ridges and a scooped out depression.
Possible health problem: cardiovascular disease, iron deficiency or anemia, lupus, hypothyroidism, Raynaud's disease, hemochromatosis. Seek medical attention.
White nails with a dark rim under the outer nail growth may be a more serious sign of a health problem than white spots. While it is widely believed that white spots are connected to calcium levels, it isn’t typically the case and you’re likely just fine.
Possible health problem: unhealthy liver function (white nails.) If you see white spots, don’t worry. But, if you suddenly see all-white nails or white lines across, check with your doctor.
Yellow nails are not always a sign of a health problem if you have your nails done often some nail polishes may turn healthy nail beds yellow
Possible health problem: fungal infection, thyroid issues, lung disease, diabetes or psoriasis. Talk to your doctor if the condition persists.
As you can see proper nail care is essential for our health, not just to monitor it, but to support it. Here are some easy tips you can use to rock healthy nails -and healthy skin- every day.
Look for foods rich in protein (keratin is a protein!), Biotin/Vitamin H, Vitamin A, collagen, Omega 3, and Zinc:
Try natural and essential oils to nourish your nails and promote healthy growth, rub one to three drops on them once a week (or up to three) to prevent artificial coloring:
Supplements can provide extra support for healthy nails, nail beds, and overall healthy skin:
Healthy nails are an outer expression of a healthy immune and integumentary system. Consuming a healthy diet rich in vitamins, minerals, and phytonutrients is the best way to support healthy nail beds and healthy skin. Include a wide variety of protein, fruits, vegetables, nuts and seeds to avoid malnutrition-related nail problems.
