- Title
Travails of microgravity: man and microbes in space.
- Authors
Lynch, S. V.; Matin, A.
- Abstract
The article presents information about the effect of space travel on human beings. The harmful effects of microgravity on humans have been documented. Astronauts can lose up to 3% of bone density per month and are, as a result, prone to increased incidence of fracture upon prolonged space residence; also, the resorbed calcium can result in kidney stones. Muscle atrophy, resulting from lack of gravitational load during movement and minimised exercise in the confines of a spacecraft, is an additional problem. Microgravity also reduces blood production, resulting in diminished pumping by the heart.
