Systems And Methods For Transdermal Electrical Stimulation To Improve Sleep
Methods and apparatuses for improving sleep by transdermal electrical stimulation (TES). In general, described herein are methods for applying TES to a subject, and particularly the subject's head (e.g., temple/forehead region) and/or neck with an TES waveform adapted to improve sleep, including reducing sleep onset (falling to sleep) more quickly and/or lengthening the duration of sleep. TES waveform(s) particularly well suited to enhancing sleep are also described herein.

- 1. A method of non-invasively reducing sleep onset and increasing sleep duration, the method comprising:
attaching a first electrode to a subject's head or neck at a first location and a second electrode to the subject's head or neck at a second location, wherein the first and the second electrode are coupled to a transdermal electrical stimulation (TES) applicator worn by the subject; applying an electrical stimulation between the first and second electrodes, wherein the electrical stimulation has a peak amplitude of greater than 3 mA, a frequency of greater than 250 Hz, and a duty cycle of greater than 10%; and continuing application of the electrical stimulation for a stimulation duration of at least one minutes to enhance sleepiness, sustain sleep or to enhance sleepiness and sustain sleep.
- 20. A method of non-invasively reducing sleep onset, the method comprising:
placing a first electrode of a wearable transdermal electrical stimulation (TES) applicator on a subject's temple region and a second electrode on a back of the subject's neck; activating the wearable TES applicator to deliver a biphasic electrical stimulation between the first and second electrodes having a duty cycle of greater than 10 percent, a frequency of 250 Hz or greater, and an intensity of 3 mA or greater, wherein the biphasic electrical stimulation is asymmetric with respect to positive and negative going phases; and reducing sleep onset by applying the biphasic electrical stimulation between the first and second electrodes for 10 seconds or longer.
- 21. A method of non-invasively inducing sleep in a subject, the method comprising:
placing a first electrode of a wearable transdermal electrical stimulation (TES) applicator on the subject's skin on the subject's temple region and a second electrode on a back of the subject's neck above a vertebra prominens; activating the wearable TES applicator to deliver a biphasic electrical stimulation having a duty cycle of greater than 10 percent, a frequency of 250 Hz or greater, and an intensity of 3 mA or greater, wherein the biphasic electrical stimulation is asymmetric with respect to positive and negative going phases; and inducing sleep by applying the biphasic electrical stimulation between the first and the second electrodes for 10 seconds or longer.
- 22. A method of maintaining sleep in a subject, the method comprising:
placing a first electrode of a wearable transdermal electrical stimulation (TES) applicator on the subject's skin on the subject's temple region and a second electrode on a back of the subject's neck above a vertebra prominens; activating the wearable TES applicator to deliver a biphasic electrical stimulation having a duty cycle of greater than 10 percent, a frequency of 250 Hz or greater, and an intensity of 3 mA or greater, wherein the biphasic electrical stimulation is asymmetric with respect to positive and negative going phases; and maintaining a state of sleep in the subject by applying the biphasic electrical stimulation between the first and second electrodes for 10 seconds or longer while the subject is asleep.
