This document discusses the physiological and physical impacts of caregiving on caregivers. It notes that caregivers have higher rates of depression, anxiety, stress, and physical health problems than non-caregivers. They also engage in less self-care like exercise and healthy eating. Future research is needed to better understand how factors like age, relationship to patient, ethnicity, and available resources affect a caregiver's ability to cope and their health risks over time. Providing more support services, education, and assistance could help reduce caregivers' burdens and stress.
