In my previous recent article about the effect of space stay or long stay on space, that it can give
you a brain problem and eye problem, now it can give you a heart problem.
Astronauts are not
only struggling brain and eye health problem during their long stay in space
but now even their hearts have a problem. Study said long stay in space can
also cause heart problem or it can induce heart attack on astronauts.
Long exposure to
microgravity and “no gravity” has a bad effect on health.
“Now, scientists have discovered that your heart
goes through major changes in space – at least temporarily….. Scientists have
known for a while that going into space is tough on your heart. Space tends to
reduce blood pressure, while dehydration leads to lower blood volume. It also
increases the amount of blood pumped through your vessels with each heartbeat,
which translates to extra work for your heart muscles. On top of that, the
radiation astronauts are exposed to during some missions can affect heart
health. The radiation causes high blood pressure – also called hypertension –
because it prevents your blood vessels from "relaxing." So, overall,
it's not a huge surprise that astronauts are much more likely to die from
heart disease than the general population.” (Sciencing)
