Weathering

Also known as: Biological weathering, racial weathering

Medically reviewed — last updated

Weathering is a hypothesis, first proposed by Dr. Arline Geronimus in 1992, that describes the physical health deterioration resulting from the cumulative biological effects of chronic exposure to social and economic adversity and racial discrimination.

Evidence includes research showing Black Americans have shorter telomeres (cellular aging markers) and earlier onset of aging-related conditions relative to white Americans of the same age. This helps explain why Black mothers with more education still face worse maternal health outcomes than less-educated white mothers.

Understanding weathering reframes health disparities as consequences of structural racism rather than individual behavior.
