This Light Bulb Could Be the Key to a Better Night’s Sleep

It was designed to help astronauts maintain normal snoozing schedules in space.

We are all very, very tired. Just 42 percent of American adults get the recommended seven to eight hours of sleep per night, according to a recent Gallup poll, and too much screen time before bed—pre-shut-eye TV, computer, or smartphone use—is only making the problem worse.

But what if getting more z’s were as easy as buying a light bulb? That’s the concept behind Lighting Science’s Good Night Biological LED Lamp, which the company says will help “to regulate your body's natural circadian rhythm.”

If this sounds far-fetched, know that the specialized light bulb was actually developed by NASA contractors to help astronauts get enough sleep while in space. Even your standard white bulb emits some blue light, which interferes with the production of the sleep-regulating hormone melatonin. The Good Night light, by contrast, puts out significantly less blue.

“When you go home at night and turn on the lights and TV, your body gets signals that it is daytime,” Lighting Science’s Robert Soler explained to a NASA publication. “If you have a regular light on next to your bed while you are reading and trying to prepare for sleep, it is suppressing the melatonin production in your body, and when you are ready to go to sleep, your body is not.”

Of course, the bulb will not do its magic if used in conjunction with blue-light-emitting technologies like TV and smartphones.

For those with the opposite problem—trouble waking up in the morning—Lighting Science makes an Awake & Alert bulb, which emits copious amounts of blue. Groggy mornings no more!

Though neither bulb has yet to travel into space, retired NASA astronaut Michael Lopez-Alegria told USA Today he hopes the lights will help space crews wake up in the morning, stay sharp during the day, and feel appropriately sleepy at night.

Seventy-five years ago, on January 27, 1945, the Soviet Army liberated the Auschwitz concentration camp operated by Nazi Germany in occupied Poland.

Auschwitz was the deadliest of Nazi Germany's 20 concentration camps. From 1940 to 1945 of the 1.3 million prisoners sent to Auschwitz, 1.1 million died. That figure includes 960,000 Jews, 74,000 non-Jewish Poles, 21,000 Roma, 15,000 Soviet prisoners of war, and up to 15,000 other Europeans.

The vast majority of the inmates were murdered in the gas chambers while others died of starvation, disease, exhaustion, and executions.
