Last week I posted a video about how cold may improve metabolism by increasing brown fat.

Well SupportedCold exposure promotes brown fat production, which revs up metabolism, burns white fat, and may secrete health-promoting factors.

Well SupportedCold water immersion and cryotherapy both induce a robust release of norepinephrine, though they differ in their ability to reduce body temperature.

Well SupportedExposing oneself to various temperatures activates brown fat because it is involved in maintaining homeostatic temperature balance.

Well SupportedNorepinephrine, a neuroendocrine hormone boosted by cold exposure, increases mitochondrial biogenesis.
