Is your Device Making you Hungry? Computer or Blue Blocking Glasses to the Rescue!

    Scroll down to watch How To Enable Nightshift. And Read About How Blue Light can Make you Hungry, Tired, and Depressed.

     

    Smartphones emit luminous blue light so you can see the display, even on the sunniest days. However, your brain gets confused by blue light at night, as those azure emissions actually mimic the sun. Makes sense, right?

    Turns Out You Don’t Have To Watch The Cooking Channel To Get Hungry

    By measuring blood glucose and insulin levels,  scientists determined that exposure to blue light from LED lighting led to an increase in hunger after just 15 minutes of exposure and get this, was still present 1.75 hours later! Yikes! And, blood levels showed altered glucose metabolism (that doesn’t sound like a good thing) and decreased levels of sleepiness (also not a good thing a night)

    The researchers concluded, “Blue-enriched light exposure immediately before, and during the evening meal acutely increases hunger..." 

    Don’t Be Blue

    Scientists figured out a while back that the timing of blue light exposure was important. In 2014, Researchers at Northwestern University decided to study evening blue light exposure and how it affects hunger, metabolic hormones, and sleepiness.

    They studied a group of healthy adults who had ‘regular’ sleep and eating schedules (that, in and of itself, deserves a study!) For 4 days, researchers gave them and compared what happened to these participants when they ate identical meals while exposed to enriched blue light in the evening vs being exposed to dim light.

    I’m Hungry. Therefore, I Eat

    Turn off the screens so that light has no chance of tweaking your natural hunger. There was a follow-up study on blue light and hunger – See the link below.

    More About Blue Light and Your Body

    This blue light actually can suppress production of the sleep-regulating hormone melatonin. Bright blue light in the evening hours can throw off your body clock, confusing your brain into thinking it’s still daytime which in turn effects our Circadian Rhythms.

    The best way to avoid the blue light from suppressing your melatonin production or disrupting your circadian rhythms is to cut back on using your phones, computers or iPads at night. The National Sleep Foundation Recommends powering down all devices 2 hours before bed. We also offer blue-blocking orange glasses and a blue blocking retina guard for your laptop or phone for when it gets dark. 

    

    Meanwhile, Tech Wellness offers another option to battle the blues: Our orange glasses for nighttime wear (also known as blue blockers). A Swiss study examined a dozen teen boys wearing orange-tinted glasses in the evening for a week. The boys reported they felt “significantly more sleepy” as compared to when they wore clear glasses. Similarly, it appears that blue light affects kids and young adults the most, due to changes in the older adult eye anatomy.

    We also offer several other pairs. A little more high quality too. My husband can't live without his!

    Another study we found discussed how blue light exposure effects your metabolism. Studies manipulating morning light exposure are typically associated with leaner body weight, lower boy fat, and altered appetite outcomes. On the other hand, later timing of light tends to be associated with heavier body weight.

    Apple to The Blue Light Rescue!

    Up until now, iPhone gave you no choice but to abandon your phone hours before bed or stay up to toss and turn–but the recent iOS 9.3 update changes all that. The new Night Shift mode can be set up manually each night at an hour of your choosing (depending on your schedule for that day) or it can be automatic.

    When Night Shift sets in, your phone auto-adjusts the screen display, so that it gives off warmer light, with 50% less blue emissions.  Blue light signals to the brain to halt a hormone that gives your body the “sleepy time“ prompts.

    Good Sleep is a Good Thing

    Disrupting the sleep cycle causes a pattern of it being harder to fall and stay asleep—and there’s a slew of serious potential effects on your body for the long-term. Here’s how blue light at night affects your brain:

    Disruption of sleep can leave you distracted the next day, making it harder to learn new tasks and disrupt memory. Chronic sleep debt causes neurotoxin buildup. Melatonin levels become suppressed and hunger hormones get disrupted, so people are more prone to depression and obesity, (the latter can lead certain cancers.) Current studies are also being done to examine a link to possible cataracts and retinal abnormalities.

    At the very least, these new habits are a pleasant change to your lifestyle and your eyes will feel a little less stressed. Go ahead, try our tips and let us know what you think!
