While large lunulae are more common in those who are very active, if you live a sedentary lifestyle and are noticing them growing in size, it could simply be a signal that you're under a lot of stress. You also need to be aware of any changes in color. While white suggests you are in good health, any other color could be a sign of something serious. Black, for example, is known to indicate heavy metal poisoning.

Ultimately, Bright Side claims that the lunula on each finger is connected to a different part of your body. The lunula on your thumb is linked to your lungs and spleen, the one on your index finger is associated with the intestine and pancreas, and your middle finger lunula is your brain and cardiovascular system. Your ring finger lunula represents your reproductive and lymphatic systems, and the little finger lunula, which is commonly invisible, stands for your kidneys, small intestine, and heart.
