Shivering can increase your metabolic rate as much as five fold.
Our bodies burn energy to keep us warm in a process called non-shivering thermogenesis (NST), they explain, which works even at pretty reasonable temperatures.
They defined mild cold exposure as 64 degrees Fahrenheit.
Do you burn more calories when it’s cold?
Cold weather itself does not increase calorie needs. You don’t burn extra calories unless your body temperature drops and you start to shiver. Your body does use a considerable amount of energy to warm and humidify the air you breathe when you exercise in the cold.

Does being cold mean slow metabolism?
Being cold all the time is a symptom of hypothyroidism, which also slows down your metabolism. If you’re cold all the time, odds are your thyroid isn’t as active as it should be—and neither is your metabolism.
Do you get colder when you lose weight?
You might feel colder.
“Your body is going to lower your metabolic rate when you lose weight to try to conserve energy,” Apovian said. “And in conserving energy, it doesn’t have a lot of extra calories to keep you warm.” Another reason you might feel colder is because you no longer have fat acting as an insulator.
