The Dubna quark confinement model is applied to the study of electromagnetic polarizabilities of the {pi} and {ital K} mesons. Within this model it is found that the effect of quark confinement reduces the value of the pion polarizability from that obtained in such approaches as chiral quark loop and linear {sigma} models. In the chiral limit our result coincides with the one found in chiral perturbation theory. For the charged kaon we find the electric polarizability considerably larger than the chiral prediction. This is due to the strong meson-mass dependence not expected from the pointlike interaction in effective meson Lagrangian approaches.
