TL;DR: It is shown that during exercise CBT rises higher and faster in space than on Earth, and questions are raised about the assumption of a thermoregulatory set point in humans, and the authors' evolutionary ability to adapt to climate changes on Earth.

TL;DR: It is suggested that forehead Double Sensor recordings may provide a surrogate for rectal temperature in circadian rhythm research, where constant routine protocols are applied and future studies will be needed to assess the sensor’s ecological validity outside the laboratory under changing environmental and physiological conditions.

TL;DR: Gender appears to be an influence, as women showed a declining sleep quality, despite that their physical activity remained unchanged, suggesting other causes such as a higher susceptibility to psycho-social stress and changes in environmental circadian rhythm during long-term isolation in Antarctica.

TL;DR: Investigating the relationship of measured temperatures at different sites during surgery in deep hypothermic patients suggests that measured surrogate temperatures as indices of the cerebral temperature should be interpreted with respect to the temporal and spatial dispersion during cooling and rewarming phases.

TL;DR: Results show that a 10-day recovery did not compensate for the cardiovascular and autonomic deconditioning following 60-day HDT, and high-intensity, short-duration exercise training effectively minimized these impairments and should therefore deserve consideration as a cardiovascular deconditionsing countermeasure for spaceflight.
