1. A system for inducing sleep in a waking user, the system comprising:
a mobile communication device; and
a headgear comprising:
a headband;
a plurality of transcranial stimulation electrodes; and
a control system disposed within the headband and in electrical communication with the plurality of transcranial stimulation electrodes, wherein the control system comprises:
an antenna configured to receive wireless communications signals from the mobile communication device;
a processor in data communication with the antenna; and
a memory device comprising instructions that, when executed by the processor, cause the processor to:
receive, via the antenna, one or more signals transmitted by the mobile communication device;
transmit a transcranial stimulation current to the plurality of transcranial stimulation electrodes for a first period of time based on the one or more signals received from the mobile communication device; and
cease transmission of the transcranial stimulation current for a second period of time based on the one or more signals received from the mobile communication device,
wherein the transcranial stimulation current is characterized by a transcranial stimulation waveform,
wherein the transcranial stimulation waveform has an amplitude characteristic and a frequency characteristic of a low-delta waveform, and
wherein the mobile communication device is to emit a sensory stimulation signal that is phase-locked with respect to the waveform of the transcranial stimulation current.
