Cold exposure increases protein breakdown, impacting metabolism and energy expenditure.
In a study on cold exposure, researchers found that the body's metabolic rate doubled when exposed to cold temperatures. They used special tracers to study how proteins are broken down and used by the body. They discovered that while the overall breakdown of proteins increased during cold exposure, the breakdown of proteins within the body's tissues did not change. This suggests that the body handles protein breakdown differently during cold exposure compared to exercise. The findings show that the body's protein breakdown increases during cold exposure, especially when compared to rest.
