Could a smart light bulb help reset your body clock?

After finishing a film on Netflix and taking one final scroll through your Facebook feed, you go to bed. It’s much harder to switch off your mind than a screen, wel, and after tossing and turning, you finally drift off. When your alarm goes off, it feels like you barely closed your eyes.

Klink bekend? It’s more common than you might think. Volgens die American Sleep Association, more than a third of adults in the US report sleeping less than seven hours a nightthe bare minimum suggested for optimum health.
For many people, our busy modern lives have put the body’s natural sleep-wake cyclecalled the circadian rhythmout of whack. Maar new research might help.
Vroeër die jaar, scientists at the University of Washington identified how cells in the eye respond to different colored lights, signaling the part of the brain that regulates our circadian rhythm. Nou, US company TUO has used those findings to create an LED light bulb it says can help energize you in the morning and calm you at night.

    Why circadian health matters

    The circadian rhythm is an internal body clock that runs in approximately 24-hour cycles, says Joey Chan, associate professor of psychiatry at the Chinese University of Hong Kong. Everyone’s circadian rhythm is different, ranging frommorning larks” aan “night owls,” sy sê.
    While the circadian rhythm is responsible for sleep, Chan says it alsoaffects our mood, our neural connections, our memory, physical performance, and the cardiometabolic functions.
    But modern living, particularly for those in cities, has disrupted this internal clock. The circadian rhythm is triggered byenvironmental stimulus,” says Chan, the most important of which is light. Exposure to light suppresses melatoninsometimes referred to as the sleep hormone.
    Our eyes are most sensitive to blue light, says Chanthe kind emitted from TV, phone and laptop screens, which is why watching TV or using your phone before bed can impact your sleepbut it turns out this isn’t the only light driving the circadian rhythm.
    Research from the University of Washington found that long wavelength orange and yellow light, along with contrasting violet lightthe colors occurring naturally at sunrise and sunsetare also important.
    Chan says this demonstrates our eyes arenot only for vision,” as the colors and not just light itself play a part in stimulating the circadian system.
    The university has licensed technology based on the findings to TUO, which has created a smart bulb that uses different types of light to either wake-up or wind-down your body clock.
    TUO co-founder and CEO David Basken says that by discreetly alternating between different light wavelengths, the bulb can stimulate the circadian system.
    Users connect to the $ 59 smart bulb with an app and set it to suit their schedule and sleep preferences. The bulb creates a lighting schedule and runs through three modes each day: wakker word, active, and calm, with an extra “gereeld” instelling. The bulb warmth or coolness and brightness can be set for any of the three modes, says Baskenall while appearing as a regular white light.
    TUO's bulb connects to an app, which creates a schedule customized to the user.

    A growing sleep health market

    Circadian lights aren’t a new idea. Circadian Optics specializes in light therapy lamps for mood disorders, while electronics company Philips has asunrise alarm clock.” Selfs NASA has tested a specialized circadian light schedule to help astronauts on board the International Space Station. Circadian health is part of a growing trend in sleep health, a market estimated to be worth up to $ 40 miljard in 2017.
    TUO says most Circadian lights are based on blue light, whereas its bulb focuses on changes in light color. Byvoorbeeld, in the morning TUO’s bulb mimics the light pulses of sunrise to wake the circadian system.
    We’re really starting to think about how we consume light,” says Basken. He highlights thatintegrated healthy lightingconcepts are already being incorporated into luxury property, but haven’t reached the mass market yet.
    This is why TUO opted for a light bulb, rather than a lamp or lighting fixture, hy sê: “It’s just a light bulb. You put it into a fixture that you like, and everyone can get access to it.Using the bulb in the areas you spend the most time in the morning and evening is a good start, says Basken.
    Natuurlik, a light isn’t a cure-all, says Chan. She emphasizes the personal nature of circadian health and the importance ofregular circadian cues” — a consistent waking and sleeping habitas well as getting lots of natural light.
    But creating a light-sensitive environment in our homes doesn’t hurt, and while it won’t completely stop the effects of TV or phone light, Basken claims creating an ambient setting with circadian bulbs can helpmitigate the effects.
      Basken hopes that TUO’s bulb will help people get back in touch with the natural rhythm of their body, and lead a lifestyle more in sync with their biological clock.
      If we’re not going to live outdoors under the sun and stars, then we have to think about what that means to our biology,” says Basken. “Light has to be an ingredient all day, for the best results. That’s really where we’re going with it.
