What Nails Can Tell about Your Health

Oct 22, 2007

Nails as well as skin are a window to inner state of your body. Healthy nails do not split or crack, have no ridges or spots, darkening and discoloration. Normally, a nail should have a transparent color, the nail bed (a skin on which the nail grows) is light pink and the surface is smooth.

Usually the whole nail plate grows in five to six months that is about 0,05 to 1,2 millimeters per week. With the age the growth of nails slows down which can be explained by the fact that blood supply becomes poorer.
