You use them to write, eat and work, but your helpful hands can do more for your health than you know. Whether it’s a risk of heart attack, nutrient deficiencies, or thyroid malfunctions, your hands can provide beneficial clues about your health.

All you need to do is look down and take a closer look at your palms, skin texture, fingernails, sweat glands, and pigment to be able to see the signs your body is showing you. Here are seven conditions or deficiencies to look for that your hands might be showing you.

7. Thyroid Function

Thyroid Function

Hypothyroidism, which is a thryoid diesease that results in an underactive thyroid, can cause swollen fingers and cold hands. Conversely, hyperthyroidism, an overactive thyroid, can show signs such as reddened or dry skin on your hands.

6. Nutrient Levels

Nutrient Levels

Do you have brittle fingernails that often break? Weak fingernails can be a sign of a zinc deficiency, as well as low levels of vitamin A, vitamin C, or biotin. Hypocalcemia (low calcium) can also be the cause of fragile fingernails. Nail ridges can also indicate a protein deficiency.

5. Hyperhidrosis


Although it is quite common to have some sweat on the hands, it is, however, uncommon to have overactive sweat glands that hinder your ability to open doors. This is a symptom of hyperhidrosis. There is usually a genetic component that begins during childhood or young adulthood that elevates the production of sweat.

4. Heart Conditions

Heart Condition

Grip strength can reveal how healthy your heart is and can even measure your risk of suffering a heart attack or stroke. Studies have shown that grip strength can be a great way to assess biological age, and also note that weaker muscle strength can make it more difficult for a person to survive a chronic medical problem.

3. Parkinson’s Disease

A shaking hand while at rest can be an indicator of Parkinson’s disease. It is important to note that this type of shaking, which occurs when the hands are not performing any activity, is different from the common trembling that most people experience from stress or caffeine intake. The shaking that happens in Parkinson’s disease is called “pill rolling” because your thumb and index fingers will move as if they are rolling a pill.

2. Oxygen Levels

Oxygen Levels

Paleness in the hands and on the nail beds can be a sign of anemia. Anemia is a condition that results in low levels of red blood cells, which lower the ability to carry sufficient oxygen to the tissues.

1. Eczema
