Condition
Circadian phase advance
Intervention
VSOM-4.16 versus placebo. VSOM-4.16 is a device that electrically stimulates peripheral sensory receptors which appears to have an indirect effect of allowing individuals undergoing an advance in the phase of their sleep schedule to fall asleep faster.
