Applicability of the actigraphy for astronauts in spaceflight
Pandi-Perumal and Gonfalone presented perspective on sleep in space by overviewing the past medical reports [3]. The authors made special emphasis on “normal sleep” in space, where no gravity exists. According to their review, sleep in space was mainly monitored by subjective sleep diaries and actigraphy (wrist-worn accelerometer). As sleep cycle was developed in response to the 24 h rotation o...
متن کاملKeeping the right time in space: importance of circadian clock and sleep for physiology and performance of astronauts
The circadian clock and sleep are essential for human physiology and behavior; deregulation of circadian rhythms impairs health and performance. Circadian clocks and sleep evolved to adapt to Earth's environment, which is characterized by a 24-hour light-dark cycle. Changes in gravity load, lighting and work schedules during spaceflight missions can impact circadian clocks and disrupt sleep, in...

متن کاملEffectiveness of an expert system for astronaut assistance on a sleep experiment.
BACKGROUND Principal Investigator-in-a-Box ([PI]) is an expert system designed to train and assist astronauts with the performance of an experiment outside their field of expertise, particularly when contact with the Principal Investigators on the ground is limited or impossible. In the current case, [PI] was designed to assist with the calibration and troubleshooting procedures of the Neurolab...
متن کاملIs Autonomic Modulation Different between European and Chinese Astronauts?
PURPOSE The objective was to investigate autonomic control in groups of European and Chinese astronauts and to identify similarities and differences. METHODS Beat-to-beat heart rate and finger blood pressure, brachial blood pressure, and respiratory frequency were measured from 10 astronauts (five European taking part in three different space missions and five Chinese astronauts taking part i...
