  In the framework of the theory of general relativity, in order to obtain
stable traversable wormholes, matter needs to violate the null energy
condition. It is well known that the violation of the energy condition (EC) of
matter leads to various physical problems. To address this issue, researchers
have turned their attention to exploring modified theories of gravity, aiming
to avoid the violation of ECs by introducing geometric terms. In this paper,
within the framework of the $f(Q)$ modified gravitational theory, we
investigate the effectiveness of ECs for matter in traversable wormholes. We
examine the compliance of four types of energy conditions (weak energy
condition, null energy condition, dominant energy condition, and strong energy
condition) in the model by selecting a power-law model for $f(Q)$ and
considering different shape functions $b(r)$. Our study reveals that for
traversable wormholes realized through the $f(Q)$ modified gravity theory using
the power-law model $f(Q)=a(-Q)^n$, all four types of ECs for matter can be
satisfied. There is no need to introduce exotic matter (violating the null
energy condition) or special matter (violating other energy conditions)
artificially in the physics of wormholes.
