The swampland is the set of seemingly consistent low-energy effective field that cannot be consistently coupled to quantum gravity. In this review cover some of the conjectural properties that effective theories should in order not to fall in the swampland, and we give an overview of their applications to particle physics. The latter include predictions on masses, bounds on the cosmological constant, the electroweak and QCD, the photon mass, the Higgs potential and some insights about.
