44% of Couples Secretly Change Thermostats as Studies Link Temperature Fights to Sex Differences

Summary
44% of U.S. couples said they secretly change the thermostat after a partner falls asleep, with nearly two-thirds disagreeing over bedroom temperature and 6% arguing about it every night.
Physiological differences help drive those fights: thermal physiologists say women generally feel colder because of lower skin temperatures, less muscle mass and hormone effects, while men often tolerate cooler rooms better.
Sleep advice complicates the standoff, with experts putting the ideal bedroom range at 16-18C and saying core body temperature needs to fall for sleep, even if one partner wants more warmth.
Technology is making the battles easier to wage, from app-controlled heating and hidden overrides to reports of dummy thermostats installed to give one partner only the illusion of control.
Relationship therapists say recurring thermostat rows often reflect deeper issues of control, respect and negotiation, especially when one partner feels dismissed, bullied or unable to express their needs.
