As a basic unit, family provides a stable environment, cultivates a healthy lifestyle, and carries out disease prevention and management, which is of great significance to the physical and mental health of its members. Families provide emotional support and a sense of security, which helps to keep healthy. Interaction and communication between family members can convey positive values and behavior patterns and form a healthy lifestyle. Family members can also supervise and remind each other, find physical abnormalities or disease risks in time, and take measures to prevent them. Family-based health care is the key to promote the healthy development of the whole family and has a positive impact on happiness and well-being.
