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.
