1. A hearing aid configured to be operated based on an estimation of a current listening effort of a hearing aid user, the hearing aid comprising
an input unit for receiving an input sound signal from an environment of the hearing aid user and providing at least one electric input signal representing said input sound signal,
an output unit for providing at least one set of stimuli perceivable as sound to the hearing aid user based on processed versions of said at least one electric input signal,
a processing unit connected to said input unit and to said output unit and comprising signal processing parameters to provide processed versions of said at least one electric input signal,
at least one physiological sensor,
wherein the hearing aid is configured to determine a current listening effort of the hearing aid user based on determining Heart Rate Variability (HRV) of the hearing aid user, and
wherein the hearing aid comprises a signal-to-noise ratio (SNR) estimator for determining an SNR in the environment of the hearing aid user.
