For the latest installment of his “Thought Glass” video series, Kevin Lieber of Vsauce2 takes a look at the origins of the phenomenon known as “spring fever,” a concept we most often associate with positive occurrences like increased energy and the lifting of depression.

However, its original connotation may have literally been with actual sickness. It’s said that America’s original colonists used the term to describe weakness and fatigue without fruits and vegetables.
