With Fewer Electronics, People Follow a Natural Sleep Cycle
Researchers have studied how towns, less influenced by tech, sleep. They've found these people's wake/sleep cycles mimic the sun's. So, what can be done to save the tech-addicted cities?
The brain uses certain cues to know when to wake up; eating gets our metabolic systems going; and light suppresses the sleep chemical melatonin. But researchers have stated again and again how artificial light from iPads and smartphones — blue light — is messing with our sleep patterns. Developers have the task of finding ways to suppress this spectrum of light that's keeping users awake at night.
Gregory Ferenstein from Pacific Standard writes on several recent studies that look at how people in cities with fewer electronics sleep. One study found that the people in the rural town of Baependi, Brazil, take more of their cues from the sun.
Malcolm von Schantz from the University of Surrey, who led the study, explained:
"The people of Baependi, particularly those in the countryside, maintain a much stronger link with the solar rhythm, largely because many of them work outdoors. Midnight really represents the middle of the dark phase, and yet many of us in the industrialized world are not even in bed by then.”
The town sleeps at sundown (around 9:30 p.m.) and wakes with the rising sun (around 6:30 a.m.), whereas people in London wake around 8:30 a.m. and go to bed around 11:15 p.m. With fewer devices to compete for their attention, they're able to detach themselves. But it's also about the kind of light these devices emit. The blue-spectrum light, the same as the rising sun, is supposed to set our bodies in motion, but instead plays tricks on our sleep/wake cycle.
After all this research, tech giants have a new niche to market if they can figure out how to shade this blue glow. One startup founder, Michael Herf, already has. His f.lux software fixes this problem. “It makes the color of your computer's display adapt to the time of day, warm at night and like sunlight during the day.”
While some consumers are aware of the risks, it's time for developers to consider how they can create night-friendly tablet devices.

As you vote, keep in mind that we are looking for a winner with the most engaging social venture pitch - an idea you would want to invest in.
Lumina Foundation and Big Think have partnered to bring this entrepreneurial competition to life, and we hope you'll participate! We have narrowed down the competition to four finalists and will be announcing an audience's choice award and a judges' choice award in May.
The creator of the winning video — chosen by Big Think's audience, the Lumina Foundation, and an independent panel of experts (bios below) — will be flown to New York for a taping in the Big Think studio as a way to further promote their vision for a new, disruptive idea in post-secondary education.
Thank you to all of the contestants who spent time submitting applications, and best of luck to our final four competitors.
Finalist: Greater Commons - Todd McLeod
Greater Commons, founded by Todd McLeod and Andrew Cull, is an organization that helps people live happier, more successful and fulfilling lives through agile learning. The current education system is inefficient and exclusionary, in which many students who end up earning a degree, if at all, enter a career not related to their field of study. Greater Commons solves this problem and gap in post-high school secondary education in a variety of ways. Passionately and diligently, Great Commons helps others obtain skills, knowledge, wisdom, motivation, and inspiration so that they may live better lives.
Finalist: PeerFoward - Keith Frome
PeerForward is an organization dedicated to increasing the education and career success rates of students in low-income schools and communities by mobilizing the power of positive peer influence. PeerForward works with partner schools to select influential students as a part of a team, systemizing the "peer effect." Research in the fields of sociology of schools, social-emotional learning, adult-youth partnerships, and civic education demonstrates that students can have a positive effect on the academic outcomes of their peers. PeerForward is unique through its systemic solutions to post-secondary education.
Finalist: Cogniss - Leon Young
Cogniss combines technology and best practice knowledge to enable anyone to innovate and share solutions that advance lifelong learning. Cogniss is the only platform to integrate neuroscience, through which it solves the problem of access by providing a low-code platform that enables both developers and non-developers to build sophisticated education apps fast, and at a much lower cost. It addresses the uneven quality of edtech solutions by embedding research-based learning design into its software. App creators can choose from a rich set of artificial intelligence, game, social and data analytics, and gamification to build their perfect customized solution.
Finalist: Practera - Nikki James
Practera's mission is to create a world where everyone can learn through experience. Today's workplaces are increasingly dynamic and diverse, however, costly and time-consuming experiential learning is not always able to offer the right opportunities at scale. Many students graduate without developing the essential skills for their chosen career. Practera's team of educators and technologists see this problem as an opportunity to transform the educational experience landscape, through a CPL pedagogical framework and opportunities to apply students' strengths through active feedback.

- Beethovan and Picasso are the perfect examples for mastering the creative process.
- Behind each of their works are countless studies and sketches.
- The lesson? Never erase anything, keep iterating, and find new paths to familiar destinations.
Upstreamism advocate Rishi Manchanda calls us to understand health not as a "personal responsibility" but a "common good."
- Upstreamism tasks health care professionals to combat unhealthy social and cultural influences that exist outside — or upstream — of medical facilities.
- Patients from low-income neighborhoods are most at risk of negative health impacts.
- Thankfully, health care professionals are not alone. Upstreamism is increasingly part of our cultural consciousness.
The Bajau people's nomadic lifestyle has given them remarkable adaptions, enabling them to stay underwater for unbelievable periods of time. Their lifestyle, however, is quickly disappearing.
- The Bajau people travel in small flotillas throughout the Phillipines, Malaysia, and Indonesia, hunting fish underwater for food.
- Over the years, practicing this lifestyle has given the Bajau unique adaptations to swimming underwater. Many find it straightforward to dive up to 13 minutes 200 feet below the surface of the ocean.
- Unfortunately, many disparate factors are erasing the traditional Bajau way of life.
