Disclosed herein are a hygienic handle assembly and related methods for automatically advancing a clean portion of a protective sleeve over a handle after use of the handle by a person. In one embodiment, an exemplary hygienic handle assembly comprises a pair of first magnetic couplers, each having a passage therethrough, and a handle extending between the pair of first magnetic couplers and having a second magnetic coupler at each of its opposing ends. Each of the second magnetic couplers may be configured to be located within at least a portion of a corresponding first magnetic coupler, wherein magnetic fields of the first magnetic coupler repel magnetic fields of the second magnetic couplers received therein such that each second magnetic coupler is magnetically suspended within the corresponding first magnetic coupler.
