New study finds that Americans believe daylight is essential to their wellbeing, yet they spend most of their time indoors

NEW YORK, May 20, 2021 /PRNewswire/ -- A majority (83%) of Americans believe that exposure to natural daylight is critical to their good health, according to a new survey. Yet the findings come at a time when Americans increasingly spend most of their time inside, underscoring the need for technologies that can simulate daylight indoors.

BrainLit, a health tech lighting company, commissioned the survey of 1,331 U.S. adults 18 years and older in May 2021 to gauge opinions around light as it pertains to health and workplace issues. The study revealed that 83% of respondents agree that natural daylight is important for good health, affecting things such as sleep cycles, mental focus, and worker productivity. However, there was lower awareness (39%) for the fact that natural daylight can be replicated through indoor lighting systems to improve health and wellbeing.

The disconnect is significant since most respondents reported spending a majority of their time indoors, with nearly half (49%) saying they are inside 12-23 hours each day. Government studies put the numbers even higher, revealing that most Americans now spend 93% of their lives indoors[1].

The survey's findings around light's impact on sleep were particularly telling. The pandemic and its quarantine measures have increased stress and changed sleep behaviors, fueling insomnia and circadian rhythm sleep-wake disorders[2] for many. The survey bore this out, with half (50%) of those under 35 years of age and nearly a third (32%) of those 35-54 reporting they are getting less sleep since the start of the pandemic.

"While the data suggests we should encourage people to spend more time outdoors, humanity has moved in the opposite direction in recent generations," said Niclas Olsson, CEO of BrainLit. "People need the health benefits of daylight, but life's circumstances don't always allow them to be outside. The good news is that BrainLit's personalized lighting can help those staying indoors by supporting the body's natural circadian rhythm, resulting in better sleep, health, and mental acuity."

At the same time, Americans prefer the benefits of natural light compared to alternative health and wellness remedies, according to the survey findings. More than half (56%) of all age groups agree that exposure to natural daylight helps them to sleep better, and 67% said that if they had not been sleeping well, they would rather find a natural solution to their sleep troubles than taking medication. Similarly, a majority of Americans (55%) would rather go outside to gain an energy boost during a stressful workday rather than drink a soda or cup of coffee. 

The survey also found that a substantial number of Americans believe natural light can benefit cognitive and performance functions as well. For example, 59% of adults agree that children require natural light to learn, while 42% believe it can relieve symptoms of hyperactivity or ADD in children. For the elderly, respondents believe light can improve symptoms of dementia and Alzheimer's, with more than 42% of respondents agreeing. And two-thirds of adults (67%) believe natural light improves worker productivity.
