Health fairs are community events that provide free or low-cost health services and information to the public. They often include screenings for conditions like high blood pressure, diabetes, and cholesterol, as well as educational resources on topics such as nutrition and exercise. These fairs typically feature booths run by healthcare professionals, local organizations, and volunteers. Attendees can ask questions, receive health advice, and learn about available resources in their community. Health fairs aim to promote wellness and encourage preventive care among participants.
