Understanding Why You Have Lines on Your Nails

6. Heart and blood vessel illnesses.

Bad circulation can reduce the amount of blood reaching your nails, which can impact how they grow and look. Health issues like peripheral arterial disease or other heart problems can show symptoms in the nails.

Final thoughts

Lines going up and down on your nails are typically a harmless indication of getting older. If you see any other changes in your nails, such as color differences, thickness variations, or if there are other symptoms along with the ridges, it’s a good idea to see a doctor. Eating well, drinking enough water, and being careful not to hurt your nails can keep them healthy and looking good. Keep in mind that your nails can show how healthy you are, so it’s important to take care of them.
