Introduction

In general, the absence of lunula (the white half-moon area) on fingernails is a normal phenomenon, related to individual differences, lifestyle habits, and environmental factors. The lack of visible lunula does not necessarily indicate a health problem. The lunula refers to the whitish, crescent-shaped area located at the base of the nail, near the junction with the skin. In daily life, maintaining a healthy lifestyle, balanced diet, and moderate exercise can help support overall well-being.

The lunula refers to the whitish, crescent-shaped area at the base of the nail where it meets the skin. Due to physiological variations among individuals, nail growth rates and appearances naturally differ—some people are simply born with more prominent lunulae. Additionally, lifestyle and environmental factors may influence the visibility of the lunula. For example, chronic sleep deprivation, excessive fatigue, high levels of stress, prolonged exposure to cold or damp environments, or frequent contact with chemicals may all affect the nails, potentially making the lunula less visible or absent. As long as the nail surface appears rosy, smooth, full, and glossy, and there are no other symptoms of discomfort, the nails can generally be considered healthy. Therefore, the lack of visible lunula is typically a normal occurrence.

In daily life, maintaining a healthy lifestyle, balanced diet, and moderate exercise can help support overall well-being.

Does a small crescent-shaped white area on the fingernail indicate cold body constitution or deficiency of qi and blood?

In general, a reduced number of lunulae (the white half-moons at the base of the fingernails) may indicate either cold body constitution or insufficient qi and blood. When determining the cause of reduced lunulae, it is important to consider other bodily symptoms collectively, rather than drawing conclusions based on this single sign alone.
