📣 We’re in The Guardian!

What makes this review especially exciting is that writer Tracy Allison didn’t just try zDen for a few nights. She has been using her zDen nearly every night since May 2025 and even packed it for a three week trip through Ireland.

We may have laughed at the “Grim Reaper’s hood” description 😂, but we love even more that zDen has become part of Tracy’s nightly sleep routine.

Thank you, Tracy, for sharing your experience and to The Guardian for featuring the zDen Personal Sleep Sanctuary.

If getting your zzz’s means looking a little ridiculous, we’re all for it. 😴

Light can affect sleep. But what about your heart? ❤️

New research published in the European Heart Journal found that greater nighttime light exposure was associated with adverse changes in heart structure and function. In a larger group followed for nearly a decade, higher nighttime light exposure was also associated with higher risks of multiple cardiovascular outcomes and cardiovascular death.

The study looked at nighttime light exposure above just 3 lux, a very dim level of light. The researchers note that light levels as low as about 3 lux may suppress nocturnal melatonin.

Take a look around your sleep space tonight. Nightlights, digital clocks, TVs, phones, and charging lights can all add unnecessary light. What can you safely turn off, cover, or eliminate?

The takeaway is not to panic about every tiny light. It is to pay attention to unnecessary light in your sleep space and make the environment as dark as reasonably possible.

Your sleep can benefit, and your heart ❤️ could too.

This research gives us another reason to pay attention to the light in our sleep space and reduce unnecessary light when we can.

This was an observational study, so it shows associations, not proof of causation.

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.

Dorms are bright, and roommates keep different schedules.

If your student is trying to sleep while their roommate is studying, gaming, or has friends hanging out, sleep quality can suffer, and that can affect focus, mood, and academic performance.

zDen creates a private “do not disturb” sleep zone and blocks 99% of sleep-disrupting light, so sleep is possible even in a shared room.
