Hydromagnetic stability of a high-pressure plasma in toroidal traps is investigated. A helical column is considered as a model of a toroidal trap. It is shown that hydromagnetic stability improves on increase of the pressure of a plasma confined in a toroidal trap with a circular or almost circular cross section. It is thus demonstrated that the hydromagnetic self-stabilization effect takes place in the case of a high-pressure plasma. It is concluded that a plasma of sufficiently high pressure can be confined stably in toroidal traps that are unsuitable for stable confinement of a low-pressure plasma. The role of the self-stabilization effect in toroidal traps of ihe Spitzer figure eight'' type, in currentless traps with noncircular cross sections and in traps of the tokamak type, is discussed.
