Space and astronomy news
Astronauts are considered by many to be an elite bunch of people; healthy, fit and capable in many disciplines. Went they travel into space they can face health issues related to weightlessness from reduction in bone density to issues with their eyesight. These are people at the peak of physical fitness but what will happen to the rest of us when space tourism really kicks off. It is likely that anyone with underlying health issues could worsen in space.
The interest driving the study is the advancement toward space tourism and the opening up of space to those less physically fit than astronauts. As space travel becomes more available to the mass population we will start to see a shift in demographic of space travellers to older, more wealthy individuals but they are more likely to have health issues. We will eventually see people with a whole multitude of conditions wanting to holiday in space, but what are the likely impacts.
Microgravity causes a redistribution of fluids around the body and can cause conditions like ‘puffy face bird leg syndrome.’ The name aptly describes the effect, the face swells up and the legs thin. It results in an increase in venous pressure in the upper body, this is fine for healthy people but heart failure sufferers are at a much higher risk. Given that there are over 100 million people around the world that suffer heart failure it is essential this is explored.
