How members put it
“DeepestSleep helps you experience a night's rest like a child again. With DeepestSleep you will feel well rested and refreshed. It’s an excellent tool for making sleep fun again!”
ShirdenNew Liberia, LA “DeepestSleep is like a digital sleeping pill.”
TalTallahassee, TN “DeepestSleep is my bedtime treat; it helps me to shut down my brain before drifting off to sleep. It is impressively effective.”
MartynGreat Britain “DeepestSleep is a sleep knockout punch.”
GrahamIrving, TX “DeepestSleep helps me to get deeper sleep and using NuCalm Rescue or PowerNap consistently helps me sleep as well. So, I use NuCalm to help aid in my sleep, both during the day and nighttime. But then I also use it to help me recover because my sleep is not perfect and I have a very intense lifestyle, and travel too much. NuCalm significantly helps me rescue and recover.”
Jim KwikRenowned Brain Coach, Podcaster, Author, and Entrepreneur “DeepestSleep is the first time in my adult life that I have ever slept without nightmare… or fear of PTSD seizure. And for the first time in thirty years, I look forward to my next night’s sleep. I cannot begin to describe my feelings of this, beginning with pure and utter relief.”
"Pila" Chiles3rd Reconnaissance Battalion, United States Marine Corps, DMZ “With NuCalm Rescue and DeepestSleep I finally began to sleep through the night again and my body has recovered in ways I thought unimaginable. Thank you NuCalm.”
Mike SquiresFormer Green Beret Combat Veteran “DeepestSleep is magical and works every time!”

The science behind DeepestSleep
Brain wave rangeDelta (4Hz - 0.5Hz)
Delta is the slowest pattern of brain activity, common in deep sleep.
NuCalm's DeepestSleep programs are designed to guide users toward delta (4Hz - 0.5Hz). The first 50 minutes is built to help you fall asleep, and that part repeats at hour 4 in case you wake in the night.
