Latinos have traditional folk health beliefs that certain illnesses can be caused by natural forces, supernatural forces, or strong emotions disrupting the body's balance. Some of these folk illnesses include tristeza from sadness, mal aire from bad air, caída de mollera from a fallen fontanelle, empacho from a blocked intestine, cólico from colic, and susto from fright. Curanderos are traditional healers who treat these folk illnesses.
