Teen Anxiety and Depression is Linked to Cell Phones
A study in the Journal of Childhood Development that came out Summer 2017 has made the connection and the study really focuses on night use of screens.
This makes sense to us at SaferTech–and not just because the kids are actively texting, going on social media and not getting to bed–but because of the screens themselves.
Not just because you’re texting or reading—but because of the wavelengths of blue light they’re emitting.
Night-Time Screen Use Isn’t Just For Teens . . . Right?
This blue light actually can suppress production of the sleep-regulating hormone melatonin. You might ask, well, doesn’t the TV have the same blue light? Well, yes it does, but Dr.’s feel the effect is more pronounced because we hold our devices so close to our faces and step up the exposure. Bright blue light can also affect our circadian rhythms, our internal clock—something that’s being talked about a lot lately as a really important key to our health and well-being. Turns out that bright lights in the evening hours can throw off your body clock, confusing your brain into thinking it’s still daytime.
The best way to avoid the blue light from suppressing your melatonin production or changing 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 OR you can try wearing these blue-blocking orange glasses when it gets dark.
And The Studies Say . . .
There’s been a couple of studies done about the efficacy of wearing them. One study(see Research tab below) from 2014 shows that teenagers who wore orange tinted glasses a few hours before sleep were significantly sleepier when they wore the glasses.
We’ve been using them around the office (after 4pm is the best time to start) and lots of people on the team tell me that their eyes simply feel more relaxed as they look at computer screens. I should mention, blue light stimulates your brain–which is a good thing in the morning and afternoon. The real issue here is to avoid the blue light in the evening and at night!
Lack of melatonin has been linked to sleep problems, inflammation, immune function, and even cancer.
I offer these on SaferTech.com. If you want to try the orange glasses, make sure you’re getting glasses that have been tested for their blue blocking abilities and one more thing: Leaving these devices on at night while you’re asleep can add to the problem. Some research has shown that our eyes can detect blue light even through closed eyelids, resulting in suppression of melatonin production. So don’t leave them on in your bedroom, turn them off or leave them somewhere else.
Blue Light Cell Connection
Also, when you turn on a light at night, you immediately send your brain misinformation about the light-dark cycle. The only thing your brain interprets light to be is day. Believing daytime has arrived, your biological clock instructs your pineal gland to immediately cease its production of melatonin.
Whether you have the light on for an hour or for just a second, the effect is the same — and your melatonin pump doesn’t turn back on when you flip the light back off.
