Are We Blind To What Truly Impacts Our Sleep?

When most of us think about the value of a good night’s sleep, we think in terms of how we feel – refreshed, energized and well-rested. But the reality is, the cumulative value of a good night’s sleep can be much greater than we imagined.

The REVOLV study, conducted by the Light and Health Research Center at the Icahn School of Medicine at Mount Sinai, found that more access to daylight at home maintains circadian alignment, improves sleep and mental health.

Brighter Days Make For Better Nights

From our hormones and stress levels to how we sleep at night and function during the day, optimizing our circadian health is critical for improving our quality of life. Daylight is the strongest external cue we have for aligning our internal clock, but we are not making the most of this natural source.

With smart windows, we can improve the way we design our homes to optimize circadian health, leading to better sleep and all the benefits that come with it.

The REVOLV Study Overview

During the COVID-19 pandemic, people spent more time at home than ever before, allowing researchers the unique opportunity to explore the impact of their home environment on their health. They tracked 20 residents at the Exo apartments in Reston, Virginia. Residents spent one week living in their apartments with View Smart Windows and another week with standard windows with blinds.

The participants wore sleeping tracking devices, completed surveys on their health and well-being, measured their light exposures and provided saliva samples for determining the dim light melatonin onset time. Melatonin is a hormone that rises about two hours prior to bed times and tells the body it is nighttime.

More Daylight in the Day = Better Sleep at Night

Sun Light Equals Good Sleep

Smart Windows

Consistent onset of melatonin with View Smart Windows compared to a 15 minute delay with traditional windows with blinds
More consistent sleep with 16 minutes of additional sleep time with View Smart Windows

“The REVOLV study demonstrates the impact of daylight on the physiological, behavioral and subjective measures of circadian health in a real-world environment. The findings highlight the importance of ensuring people are exposed to circadian-effective electric light or daylight indoors as well as outside for human health and well-being.”
