This chronic cold stress triggers a hypermetabolic response that may limit the utility of mice in modeling hypermetabolism in response to burns. To evaluate the effect of housing temperature on burn-induced hypermetabolism, mice were randomly assigned to receive sham, small, or large scald burns. Mice recovered for 21 days in metabolic phenotyping cages at 24 °C or 30 °C. Regardless of sex or sham/burn treatment, mice housed at 24 °C had greater total energy expenditure (TEE, P < 0.001), which was largely attributable to greater basal energy expenditure (BEE) when compared to mice housed at 30 °C (P < 0.001). Thermoneutral housing (30 °C) altered adipose tissue mass in a sex-dependent manner. Compared to sham and small burn groups, large burns resulted in greater water vapor loss, regardless of housing temperature (P < 0.01). Compared to sham, large burns resulted in greater BEE and TEE in mice housed at 24 °C, however, this hypermetabolic response to large burns was blunted in female mice housed at 30 °C, and absent in male mice housed at 30 °C. Locomotion was significantly reduced in mice with large burns compared to sham and small burn groups, irrespective of sex or housing temperature (P < 0.05). Housing at 30 °C revealed sexual dimorphism in terms of the impact of burns on body mass and composition, where males with large burns displayed marked cachexia, whereas females did not.
