Longer stay in space can shrink human heart | Study

India Today  

Researchers have found that a longer stay in space can shrink a person's heart. The researchers analysed data from retired astronaut Scott Kelly's almost one-year-long stay on the International Space Station in 2015-2016. The study revealed that both the men lost mass in their heart's left ventricle over time, the Daily Mail reported. "The heart is remarkably plastic and especially responsive to gravity or its absence," leader of the study Professor Benjamin D Levine at University of Texas Southwestern Medical Centre was quoted as saying.

In space, your heart gets smaller. Based on the experience of Kelly and other astronauts on the space station, “They’ll probably be OK,” Levine said. “There’s a big question as to the appropriate intensity and duration of exercise,” said Dr. James MacNamara, a cardiology fellow at the University of Texas Southwestern Medical Center and another author of the paper. Kelly …

Staying in Space for Longer Periods of Time Shrinks Astronauts' Hearts, Exercise Can't Help Either

News 18  

Researchers have divulged the findings of a study that could be potentially a cause of concern for future astronauts-those who stay in space for long duration can experience shrinking of the heart and exercising is not of much help either. Researchers had studied data found from retired astronaut Scott Kelly’s space stay at the International Space Station from 2015 to …

CNN — When astronaut Scott Kelly spent nearly a year in space, his heart shrank despite the fact that he worked out six days a week over his 340-day stay, according to a new study. “The heart gets smaller and shrinks and atrophies, but it doesn’t become weaker – it’s just fine,” said Levine, who is also director of the …
