Pregnant women are actually driven to clean and organize because of evolution.
That’s according to a new study from McMaster University.
It’s commonly known as nesting and the researchers say it is a mechanism aimed at protecting and preparing for the unborn baby.
They say it’s characterized by unusual bursts of energy and a compulsion to organize the home.
The researchers say women also become more selective about the company they keep, preferring to spend time only with people they trust.
The research is published online in the journal Evolution & Human Behaviour.
