Human spaceflight has been fascinating man for centuries, representing the intangible need to explore the unknown, challenge new frontiers, advance technology and push scientific boundaries further.
A key aspect of long-term human spaceflight is the physiological response and the consequent microgravity (0G) adaptation, which has all the features of accelerated aging involving almost every body system: muscle atrophy and bone loss, onset of balance and coordination problems, loss of functional capacity of the cardiovascular system.
A research published in recent days in npj Microgravity – a prestigious journal of the Nature group “Cardiovascular deconditioning during long-term spaceflight through multiscale modeling”) – and conducted by Caterina Gallo, Luca Ridolfi and Stefania Scarsoglio shows that human spaceflight reduces exercise tolerance and ages astronauts’ heart.
