Description
OBJECTIVES:
This experiment investigated the circadian rhythm of core temperature and the thermoregulatory and cardiovascular adaptations during rest and exercise in the course of a long-term microgravity exposure on the International Space Station (ISS). The data derived might be important not only to understand human adaptation in space in view of the thermoregulatory and cardiovascular system, but as well as associated to problems dealing with body weight loss and de-synchronization of internal rhythms which affect the overall health and performance of astronauts/cosmonauts.

Measuring core body temperature is not straightforward because a thermometer must be placed close to the heart for best results. Many types of thermometers exist, from the type that goes under the tongue to the type that goes into the ear, but unfortunately the most accurate way of reading a core temperature is inserting a thermometer in the rectum. Body temperature tends to be lower in the feet and lowest in the early morning hours between four and six.
