Most of us are attached to our smartphones at the hip — literally. In the digital age, roughly six out of seven billion of us own a mobile device, using it to talk, text, email, and even stream episodes of our favorite shows. This all seems to be harmless, habitual and automatic behavior that we hardly notice, but the popular gadget is doing a lot more to the mind and body than we think.
In AsapSCIENCE’s latest video, “How Is Your Phone Changing You?” host Mitchell Moffit explains high usage of smartphones can change our body posture and brain function. When we look down at our phone, our spine angle is equivalent to that of an 8-year-old child sitting on our neck, according to AsapSCIENCE. This is fairly significant considering we spend an average of 4.7 hours a day looking at our phones.
Unsurprisingly, cellphones have changed our eyesight — for the worse. Staring at our phones and sitting in front of the computer has led to an increase in the prevalence of myopia, or nearsightedness, in North Americans. In the 1970s, about one-fourth of the population had myopia, while today nearly half do, and in some parts of Asia, 80 to 90 percent of the population is now nearsighted.
