Study: Even just a little light in your bedroom at night can heighten depression
Put down that cell phone before bed. Sleeping with even a little bit of light in your bedroom at night can heighten depression.
Sleeping with even a little bit of light in your bedroom at night can heighten depression, says a new study from the American Journal of Epidemiology.
Even when other factors were taken into consideration — like whether the patients smoked, ate poorly, etc — this increase in light in the bedroom accounted for a big jump in depression. 900 elderly Japanese patients were studied over the course of 2 years and it was found that those with over 5 lux had a higher chance of developing depression by 60-65%. Out of the 900 people in the study, just 150 of those slept in rooms with more than 5 lux.
A 'lux' is roughly the amount of light emitted from a candle 1 meter away. To put things in perspective, ABC News reports that a bedroom at night with the lights on is roughly 50 lux, while being outside in bright sunlight can reach anywhere from 10,000 to 25,000 lux.
The study appears to show a correlation between circadian rhythms and light exposure and depression. With more and more people using their phones, tablets, and computers in the bedroom well into the night hours, this appears to lead to a higher risk of developing depression. Lack of sleep can a wide array of other health problems, including depression, weight gain, and even cancer.
What can 3D printing do for medicine? The "sky is the limit," says Northwell Health researcher Dr. Todd Goldstein.
- Medical professionals are currently using 3D printers to create prosthetics and patient-specific organ models that doctors can use to prepare for surgery.
- Eventually, scientists hope to print patient-specific organs that can be transplanted safely into the human body.
- Northwell Health, New York State's largest health care provider, is pioneering 3D printing in medicine in three key ways.
Torn between absolutism on the left and the right, classical liberalism—with its core values of compassion and incremental progress whereby the once-radical becomes the mainstream—is in need of a good defense. And Adam Gopnik is its lawyer.

As Game of Thrones ends, a revealing resolution to its perplexing geography.
- The fantasy world of Game of Thrones was inspired by real places and events.
- But the map of Westeros is a good example of the perplexing relation between fantasy and reality.
- Like Britain, it has a Wall in the North, but the map only really clicks into place if you add Ireland.
The lost practice of face-to-face communication has made the world a more extreme place.
- The world was saner when we spoke face-to-face, argues John Cameron Mitchell. Not looking someone in the eye when you talk to them raises the potential for miscommunication and conflict.
- Social media has been an incredible force for activism and human rights, but it's also negatively affected our relationship with the media. We are now bombarded 24/7 with news that either drives us to anger or apathy.
- Sitting behind a screen makes polarization worse, and polarization is fertile ground for conspiracy theories and fascism, which Cameron describes as irrationally blaming someone else for your problems.
