Clinical Trial Highlights
Increased Restorative Sleep
Objective data showing increased deep and REM sleep (restorative sleep) was obtained via WHOOP, a wrist-worn wearable biometric device that accurately tracks sleep data.
No Side Effects
Defined Sleep had no effect on heart rate or heart rate variability in study participants. Further, no negative side effects were reported by participants, despite careful tracking by a medical monitor.
Non-sedating
Defined Sleep is a promising alternative to most prescription sleep medications and over-the-counter (OTC) sleep aids that act as strong sedatives and deprive users of restorative sleep.
Increased Efficacy
Participants who perform night-shift work were highly responsive to treatment with Defined Sleep to increase their restorative sleep.
