To the trained eye the nail bed can be a quick way to
evaluate a person’s overall health. The nails can show signs of both physical
and mental disease. A bluish tint could be a sign that the affected person is suffering
from some kind of lung disorder. This is because of how clear the fingernails
are. They can show if a person’s blood isn't getting enough oxygen. Similarly,
especially red nail beds could be a sign of heart disease. Something that I
found particularly interesting is that a skin disease called Psoriasis can also
show on the nail surface. This would like rippling on the nail surface. According
to Joshua Fox, MD, director of Advanced Dermatology, obsessive compulsive
disorder is likely to be the cause of persistent nail-biting or nail picking.
Make sure you pay attention to the changes in your nail, they could be a give
away to problems with your health.
