A method of neurostimulation may include delivering an electrical signal to a plurality of electrodes connected to a patient. The electrical signal may include an amplitude and a carrier frequency. The method may include modulating the electrical signal based on an audio waveform. In some embodiments, the modulating may include modulating at least one of the amplitude and the carrier frequency based on the audio waveform to modulate the electrical signal.

The methods, systems and devices provided herein relate to sleep-aid. Some embodiments include a vibration source and/or a sound source. In some embodiments, the vibration source and/or sound source emit vibrations and/or sounds that stimulate a subject's vagus nerve, or another nerve, to induce sleep or relaxation in the subject.

The present invention relates to a sleep-inducing system using carbon dioxide. The sleep-inducing system includes a mixed gas generation unit which generates a mixed gas of which a carbon dioxide concentration is within a preset range by mixing provided carbon dioxide and air, an emission unit which sprays the mixed gas from a position spaced apart from a user's face, a concentration sensing sensor which measures the carbon dioxide concentration of the sprayed mixed gas, and a control unit which controls the carbon dioxide concentration of the mixed gas generated by the mixed gas generation unit to be within the preset range on the basis of the measured carbon dioxide concentration.

The invention provides self-care boxes and methods for using the self-care boxes for purposes such as self-expression, relaxation, enhanced self-awareness, and self-discovery.

A method of neurostimulation may include delivering a modulated electrical signal to a patient through galvanic vestibular stimulation (GVS) and delivering a time varying thermal waveform to the patient through caloric vestibular stimulation (CVS) simultaneous with the delivery of the modulated electrical signal through GVS.

A circadian rhythm shifting method to improve future therapy effectiveness including receiving a future therapy indication, identifying a circadian cycle period that performance of the therapy is preferred, receiving a user normal circadian rhythm indication, defining a user circadian performance time range, identifying a circadian shift to change the user circadian performance time range, defining a user circadian shift protocol to cause the identified circadian shift, and providing an indication to perform an activity of the user circadian shift protocol.

A fragrance suitable for a user can be provided. A mobile terminal includes: an acquisition unit that acquires a psychosomatic state from a physiological index of a user; an input unit that inputs future information of the user; a determination unit that determines a recipe including one or more types and a mixing ratio of one or more perfumes based on the psychosomatic state and the future information; and a communication unit that transmits the recipe to a fragrance generation device.

A method of neurostimulation may include delivering an electrical signal to a plurality of electrodes connected to a patient. The electrical signal may include a plurality of spaced-apart packets of electrical pulses. The method may include modulating at least one of a quantity of the plurality of electrical pulses within ones of the plurality of packets of electrical pulses, a width in time of the plurality of electrical pulses within ones of the plurality of packets of electrical pulses, an amplitude in voltage of the plurality of electrical pulses within ones of the plurality of packets of electrical pulses, a separation in time between adjacent ones of the plurality of electrical pulses within ones of the plurality of packets of electrical pulses, and a separation in time between adjacent ones of the plurality of packets of electrical pulses to modulate the electrical signal.
