A smartphone’s glow is often the first and last thing we see as we wake up in the morning and go to sleep at the end of the day. It is increasingly becoming an extension of our body that we struggle to part with. In a recent study in Computers in Human Behavior, scientists observed that staying away from smartphones can even change one’s brain chemistry.

The human brain continuously processes the wide range of information it acquires from the outside world. Over time, this information is organized into mental representations, referred to as “schema,” which help us to understand what is happening at a given time and make predictions about what will happen next.
