Researcher Erik Fransen from Stockholm’s KTH Royal Institute of Technology says that we need to take our brain “offline” –aka off Facebook, to help our memory. He explained that working, or short-term memory, is what we use when we work online, but it has limited storage. Research shows we can hold up to 3 or 4 items in our working memory at any given time. But fill up your brain with Facebook and you our ability to process information begins to fail—not saying that some people’s posts aren’t really, really important. Fransen says that the brain is designed for both activity and relaxation, and if we keep it maxed out with technology, it can’t work properly.
