This got me thinking. As a single woman who lives with two female friends, I could crank up the central heating for a solid three hours most nights without judgement if I really wanted to (I wouldn’t – I’m conscious of the effects on the climate, after all). So I’ll happily investigate any reason to feel smug about the fact that I can freely prance around a heated flat on a freezing winter’s night. The fact that it’s potentially a rare act of “single privilege” is just the cherry on top.

Is the central heating causing arguments between heterosexual couples up and down the country? And do most men really insist on turning blue before turning on the radiators? The answer is yes. In 2017, a study found that one in three couples argued over the heating in their home.

And there’s science to help explain why.
