We’re all familiar with the word nostalgia, however most of us have no idea where it came from. It was actually coined in 1688 and was considered an illness, believe it or not. It was originated by Johannes Hoffer, a doctor, who referred to it as a neurological disease of demonic causes.
Centuries later, researchers have changed their perception of the term and now understand it to be a pleasant and normal feeling that we all experience at some point.
What’s even more interesting, is that researchers discovered that nostalgia is not merely mental, but it’s physical too. In 2012, a psychology researcher together with his team performed several studies to observe the relationship between temperature and nostalgia.
It was shown that cold temperature caused more nostalgia in comparison to warm temperature. The ability of nostalgia to make us feel better is not only related to temperature.
Concentration camp survivors for example are shown to recall satisfying meals from the past when they were starved.
