Why is it always so cold in offices?

It's summer. It's hot. Some days it's muggy.

Summer is the season to show off hard-earned physical improvements like more toned calves and triceps that you may have worked for in the winter months. It's also a time to show off tanned complexions -- sometimes earned at pools and on beaches and sometimes purchased at tanning salons.

Plus, for many women, summer is a time when sleeveless shirts, dresses and skirts are appropriate attire to combat the heat.

Because workplace offices are often freezing cold.

But why is wearing light clothing sometimes unbearable and uncomfortable?

Yes, air conditioning is a nice escape from the sweltering heat outside, but sometimes, too much cold air is undesirable.

So why is it so cold? And why do so many women have to bring cardigans and light blankets to work while their male colleagues barely notice the temperature?

A piece published in The Washington Post in July 2015 points to "the gender divide -- thermostat edition," alleging air conditioning is a "big, sexist plot."

"All these women who actually dress for the season -- linens, sundresses, flowy silk shirts, short-sleeve tops -- (change) their wardrobes to fit the sweltering temperatures around them," Post reporter Petula Dvorak wrote. "And then there are the men, stalwart in their business armor, manipulating their environment for their own comfort, heaven forbid they make any adjustments in what they wear."
