Your cell phone, TV, digital clock, & bedside lamp are all light sources that you may not realize are negatively affecting your sleep quality. zDen also blocks out light from roommates who have different sleep and study schedules, plus night lights which make it safe for you to walk around, but adversely affect sleep. Plus, zDen is portable so you can get quality sleep when you travel. zDen — A better sleep solution

Want better sleep? Start with your sleep hygiene.

Sleep hygiene is about the habits, routines, and environment that help create the conditions for quality sleep. In this video, Danielle shares a few simple, realistic changes you can try, from making your sleep schedule more consistent to creating a wind-down routine and taking a closer look at your sleep space.

The goal is not to change everything at once. Choose one thing, try it consistently, and pay attention to how you feel.

A review is great. But learning that someone has been using their zDen nearly every night for more than a year? That says a lot. 😴

The Guardian writer Tracy Allison purchased her zDen in 2025 and has been using it ever since. She even packed it for a three-week trip through Ireland. And yes, she had some pretty funny things to say about how it looks. 😂

We’ll happily embrace the “Grim Reaper’s hood” comparison if it means getting your zzz’s.

Thank you, Tracy, for putting zDen to the test and sharing your experience.
