In recent years,the demand for health care has spread from the"silver family"to the youth group,and gradually formed a youth health boom.This paper uses the semi-structured interview method to summarize the basic characteristics of young people's health preservation,and probes into the causes of the popularity of health preservation among young people and its guiding strategies.The study found that young people's mental health was characterized by rationalization and digitalization.The behavioral characteristics of health preservation are diversified expression and one-dimensional physical empowerment.The intrinsic reason for the preservation of health in youth is that health preservation is a health practice based on the human need for self-preservation.The external reasons are the"silent resistance"of youth under the background of social transformation,the"integration"of health subculture,public health emergencies threatening people's life safety,and the increasing trend of younger diseases.Based on this,the guidance of the phenomenon of youth health should be carried out from four aspects:removing body misreading,deepening youth's rational cognition of health,improving social security,reducing youth's survival pressure,improving public health services,building life and health community defense lines,leading the development direction of health culture,and building a healthy spiritual home for young people.
