Healthy user bias refers to a type of selection bias that occurs in epidemiological studies and health research when the individuals who participate in the study are generally healthier than the general population. This bias can distort the findings of such studies and lead to overestimations of the effects of an exposure or treatment, or underestimations of the risks associated with certain behaviors or conditions.
