Exertional fatigue, sleep loss, and negative energy balance increase susceptibility to hypothermia
Andrew J. Young,John W. Castellani,Catherine O'Brien,Ronald L. Shippee,Peter Tikuisis,Lloyd G. Meyer,Laurie A. Blanchard,James E. Kain,Bruce S. Cadarette,Michael N. Sawka +9 more
TL;DR: Chronic exertional fatigue and sleep loss, combined with underfeeding, reduced tissue insulation and blunted metabolic heat production compromised maintenance of body temperature and thermal balance in the cold remained compromised until after several weeks of recovery when tissue insulation had been restored.

Reproducibility of the cold-induced vasodilation response in the human finger
TL;DR: Great variability was found in the temperature response of the finger pad than the nail bed, but for blood flow the variability was similar between locations, while Variability in onset and apex time between sites was similar for both temperature and blood flow responses.

Energy Expenditure in Men and Women during 54 h of Exercise and Caloric Deprivation
John W. Castellani,James P. DeLany,Catherine O'Brien,Reed W. Hoyt,William R. Santee,Andrew J. Young +5 more
TL;DR: TEE, when normalized or corrected to body mass and fat-free mass, and PAL were the same for men and women, and total energy expenditures were among the highest observed for a military FEX.

Methods of Evaluating Protective Clothing Relative to Heat and Cold Stress: Thermal Manikin, Biomedical Modeling, and Human Testing
Catherine O'Brien,Laurie A. Blanchard,Bruce S. Cadarette,Thomas L. Endrusick,Xiaojiang Xu,Larry G. Berglund,Michael N. Sawka,Reed W. Hoyt +7 more
TL;DR: Comprehensive evaluation of PPE begins with a biophysical assessment of materials using a guarded hot plate to determine the thermal characteristics (thermal resistance and water vapor permeability) and data may be used in biomedical models to predict thermal strain under a variety of environmental and work conditions.

Dietary tyrosine benefits cognitive and psychomotor performance during body cooling
TL;DR: Findings that dietary tyrosine supplementation is effective for mitigating cold-induced cognitive performance such as working memory, even with reduced core temperature, are extended to include the psychomotor task of marksmanship.
