Imagine if something as simple as stepping outside into the daylight could add years to your life. A study out of the U.K., involving 90,000 people wearing wrist devices equipped with light sensors, suggests this might not be far-fetched. The findings were eye-opening: those soaking in the brightest daylight hours had a 17% to 34% lower risk of dying early compared to those stuck in dim, shadowy routines. It’s not just about sunshine - it’s about light itself, emerging as a surprising player in our health and longevity. Could our modern indoor lives be quietly costing us more than we realize?
To dig deeper into how Americans are faring with daylight exposure, Sleep Junkie commissioned a survey of 3,018 respondents. They asked how much time they spent outdoors this past winter. The results paint a vivid picture of a nation split between those embracing the crisp winter air and those hunkering down inside - potentially at a cost to their well-being. They also nudge us to reconsider our habits as spring starts stretching the days ahead.
On average, the survey found that New Yorkers spent just 25 hours and 30 minutes outdoors over winter. That's just 2 hours 50 minutes per week in the natural light.
Nebraskans topped the list for the least time outdoors, clocking just 11 hours and 42 minutes total over the winter months. That breaks down to a measly 1 hour and 18 minutes per week - barely enough time to shovel a driveway, let alone soak up some rays. Brutally cold winters and early sunsets likely play a role.
On the flip side, Idahoans led the pack, averaging a hearty 3 hours and 57 minutes per week - totaling 35 hours and 33 minutes over the season - likely buoyed by an outdoor culture that nudges people outside, even in the chillier months.

The survey didn’t stop at tracking hours - it sought to find out why New Yorkers stayed inside and how they felt about light in their lives. Here’s what they found.
Why Didn’t You Spend More Time Outdoors This Winter?
When asked what kept them indoors, 60% of respondents pointed to the obvious culprit: cold weather - nobody’s eager to freeze. But 17% blamed the early darkness, a reminder of how winter’s short days can shrink our world. Another 11% cited packed schedules with work or school, while an equal share admitted they just prefer the cozy allure of indoor activities. It’s a mix of practical hurdles and personal choices, but it’s clear the elements hold the biggest sway.
Do You Chase the Light When You’re Stuck Inside?
For those logging hours indoors, 80% said they make a point to sit near windows or in well-lit spots while working or studying. The other 20%? Not so much. It’s a small habit that could make a big difference, especially when outdoor time is scarce.
Are You Taking Vitamin D Supplements to Make Up for It?
With sunlight in short supply, 53% of respondents said they take vitamin D supplements or food rich in the vitamin to bridge the gap, while 47% skip them.
Would a Longer Life Get You Outside?
85% said they’d tweak their daily routine if they knew 30 minutes outdoors could lower their risk of dying early. Only 15% shrugged it off. That’s an overwhelming number of people willing to trade a little Netflix for a shot at a longer life - proof that the right motivation can move the needle.
Does Where You Live Make Outdoor Time Easy?
When asked if their state offers enough public spaces to encourage winter activity, 64% of New Yorkers gave a thumbs-up, while 36% felt shortchanged. Think parks, trails, or even well-lit plazas - places that invite you out even when the air bites.
Does Daylight Actually Perk You Up?
A whopping 88% said they feel more energized and alert on days when they get decent natural light, with just 12% claiming it doesn’t faze them. It’s a near-universal boost, backing up what science is starting to shout: light isn’t just nice - it’s a need.
Sunlight vs. Screentime: Who Won This Winter?
73% admitted they racked up more screentime than sunlight this winter, leaving only 27% who tipped the scales toward the sun. It’s a revealing stat in our tech-drenched age, where glowing screens often outshine the real thing.
“Our bodies are finely tuned to the natural rhythms of light and dark, possessing an internal circadian clock that is synchronized by light,” says Dr. Stuart Peirson for Sleep Junkie. “As such, exposure to natural outdoor light – even for just 30 minutes a day – is important to ensure the correct alignment of our circadian clock, which is essential for our sleep quality and overall health. When our circadian rhythms are correctly aligned they optimize our performance and mood and potentially reduce long-term health risks. In today’s digital age, where artificial light often disrupts our internal clocks, exposure to natural daylight is one of the simplest yet most powerful ways to improve our circadian rhythms and improve our physical and mental health.”
