Preventive health care focuses on measures taken to prevent diseases and maintain overall health rather than treating illnesses after they occur. This includes regular check-ups, vaccinations, and screenings that help identify potential health issues early. By prioritizing prevention, individuals can reduce the risk of chronic diseases such as diabetes and heart disease. Additionally, preventive health care encourages healthy lifestyle choices, such as a balanced diet, regular exercise, and avoiding harmful habits like smoking. These proactive steps not only enhance quality of life but also lower health care costs in the long run, benefiting both individuals and the broader community.
