When hot flashes wake you up

If hot flashes or night sweats wake you in the night, many women find it easier to get back to sleep with Defined Sleep. And in our clinical trial, people got up to 2x more deep and REM sleep.

Doctor recommended

“I recommend Defined Sleep to women in menopause because it’s backed by a published clinical trial, and it won’t leave you groggy in the morning.”
