Stress in space for life on Earth

Alexander Choukèr, Senior Physician and Associate Professor at the Department of Anaesthesiology, Lecturer at the Ludwig Maximalians University, Munich

  • Astronaut’s bodies take a lot of stress in space, from cardiovascular to regulation of their body temperature.
  • What is the cause of this stress and how can we avoid this?
  • Research is conducted on the ISS but ground-based facilities form an important part of studies.
  • Studying space flight has led to understanding obesity.
  • An astronaut study of salt intake on Mir led to findings that salt intake has a direct relation to blood pressure
  • Salt intake also influences bone loss. By cutting down on salt, less bone is lost in astronauts. The benefits for people on Earth apply to sufferers of osteoporosis.
  • Microbes in space become more active, uniquely these organisms seem to benefit from microgravity.
  • Studying microbe activity in space led to better vaccines.
  • When stress goes up, our immune system weakens. The source of this stress is from the brain; studies now are looking at how our brains influence the immune system when under stress.
  • Another stress factor is radiation. The Matroshka module on the ISS is analysing radiation received in space. This research allows us to target hard-to-reach brain tumours without damaging the brain itself.
  • The role of space for human life sciences: offering studies of humans under stress showing rapid onset of health problems beneficial for study.

    Dear Sirs,
    It was a pleasure to participate as an expert to the DLR Gospace Intitiative in the ISS Symposium 2012. Thank you for the fantastic organisation and great presentations and discussions. However as a space life science specialist I’m disappointed that the very interesting presentation of Dr. Chouker cannot be downloaded on this site. Reason is that despite taking many notes during his presentation I missed several publication references quoted on his charts. He went too fast…
    How should I access the document?
    Thank you for your support
    Jean Cornier

      We are working on putting all the presentations online in collaboration with the speakers themselves. I will notify you personally once I have Dr. Chouker’s presentation.

      Kind regards,
