The cheapest form of healthcare is preventive care. This includes regular check-ups, vaccinations, and screenings that can be used to identify potential health issues before they become larger problems. Preventive care also includes lifestyle changes such as exercise and healthy eating habits which can help prevent illness altogether. Additionally, many employers offer free or low-cost wellness programs that focus on preventive care measures like these, making them an affordable option for those without insurance coverage. Lastly, there are community health clinics all over the country that provide basic medical services at reduced costs or even free of charge depending on individual circumstances.
