StemCell Therapy

The effects of spaceflight on the human body have been studied actively since the mid-20th century and it is widely known that microgravity influences metabolism, heat regulation, heart rhythm, muscle tone, bone density, the respiration system.

Last year research from the US also found that astronauts who travelled into deep space on lunar missions were five times more likely to have died from cardiovascular disease than those who went into low orbit, or never left Earth.

Astronauts are fitter than the general population and have access to the best medical care, meaning that their health is usually better than the general population. Those of comparable age but who never flew, or only achieved low Earth orbit, had less than a one in 10 chance of death from cardiovascular disease.

But the chance of death rose to 43 per cent for those who reached the Moon or deep space, probably because of the impact of deadly space radiation.
