To all the women bundled in sweaters and blankets in your office air conditioning even though it’s 100 degrees outside: A recent study says that it’s not all in your head. It really IS cold.

As many women bundle up against the arctic air conditioning, their male counterparts one cubicle over have no idea what all the fuss is about. It turns out that science says the office A/C may be biased toward temperatures that more comfortable for men — thanks to a formula from more than 50 years ago.

A 2016 study in the journal Nature Climate Change notes that the temperatures in many office buildings are based on a formula developed in the 1960s that employs the resting metabolic rate of 154-pound, 40-year-old man.

More than half a century later, the workforce is much different, but the thermostat isn’t. Half of the workforce is now female, and many of them are wrapping themselves up in blankets to be able to type without shivering. The new study finds that females prefer the average temperature at home and in the office to be 77 degrees, compared to 71.6 degrees for men.

“Women tend to have lower basal metabolic rates, so they tend to burn off energy a lot slower,” Dr. Devi Nampiaparampil of NYU School of Medicine told TODAY. “They actually give off less heat than men, so they tend to be colder.”

The summer heat also usually dictates clothing choices that can have women taking outdoor breaks to thaw themselves out in order to escape their air-conditioned offices.
