All day long, we’re inundated by interruptions and alerts from our devices. Smartphones buzz to wake us up, emails stream into our inboxes, notifications from coworkers and far away friends bubble up on our screens, and “assistants” chime in with their own soulless voices.
Such interruptions seem logical to our minds: we want technology to help with our busy lives, ensuring we don’t miss important appointments and communications.
But our bodies have a different view: These constant alerts jolt our stress hormones into action, igniting our fight or flight response; our heartbeats quicken, our breathing tightens, our sweat glands burst open, and our muscles contract. That response is intended to help us outrun danger, not answer a call or text from a colleague.
We are simply not built to live like this.
Our apps are taking advantage of our hard-wired needs for security and social interaction and researchers are starting to see how terrible this is for us. A full 89% of college students now report feeling “phantom” phone vibrations, imagining their phone is summoning them to attention when it hasn’t actually buzzed.
Another 86% of Americans say they check their email and social media accounts “constantly,” and that it’s really stressing them out.
Endocrinologist Robert Lustig tells Business Insider that notifications from our phones are training our brains to be in a nearly constant state of stress and fear by establishing a stress-fear memory pathway. And such a state means that the prefrontal cortex, the part of our brains that normally deals with some of our highest-order cognitive functioning, goes completely haywire, and basically shuts down.
“You end up doing stupid things,” Lustig says. “And those stupid things tend to get you in trouble.”
Your brain can only do one thing at a time
Scientists have known for years what people often won’t admit to themselves: humans can’t really multi-task. This is true for almost all of us: about 97.5% of the population. The other 2.5% have freakish abilities; scientists call them “super taskers,” because they can actually successfully do more than one thing at once. They can drive while talking on the phone, without compromising their ability to gab or shift gears.
