Light is the enemy of sleep. Fatigue, loss of focus, moodiness, decreased memory, and a weakened immune system are just a handful of the issues that can result from poor-quality sleep. Sleeping in a dark room is ideal for your overall health.

zDen instantly blocks up to 99% of light to nurture higher quality sleep. While black-out curtains are generally effective for blocking outside light sources, zDen helps shield you from the lights within your sleep space. Your cell phone, TV, digital clock, and bedside lamp are all light sources that you may not realize are negatively affecting your sleep quality. According to a 2022 study conducted by Northwestern University, even moderate ambient lighting during sleep can adversely affect your health.

As many as 70 million Americans of all ages have sleep-related problems, and over 65 million suffer from conditions where light sensitivity is prevalent. Too much light in a sleeping environment prevents the body’s natural production of melatonin which helps you fall asleep. By blocking up to 99% of light, zDen aids in the production of melatonin which leads to better sleep.

Simply open or close the interior window flaps and the front drapes to create a sleep environment with the level of light and ventilation that is most comfortable for you. 

Sleeping well is just as important as eating well and exercising regularly. 7-8 hours of sleep, each night is essential for mental and physical health, but the quality of that sleep is just as crucial. zDen creates a dark to pitch dark environment which is ideal for high-quality sleeping. Now you can block light day or night, particularly if you suffer from a condition that increases your light sensitivity. zDen is also perfect for shared sleeping spaces and for night shift workers who need to sleep during the day. Sleep when you need it most, with zDen.
