On my recent article I mentioned that long stay in space can have a negative
effect on astronauts’ health and particularly their brain which then have effect
on their eyes or eyesight. Now, the astronauts’ heart.
Long stay in space according to new can increases blood pressure or
pressure on the heart thus causing cardiac arrest or heart attack or the
astronauts will have heart health problem or cardio disease. It will break your
heart.
Microgravity and “No Gravity” not only affects the astronauts’ bones and
muscles and their brains and eyes but also their hearts. Thus, it is health hazardous
staying long in space it can kill you.
“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)
The main point :
Long stay in space is proven to be not healthy as it can cause health problems
now on astronauts’ hearts. It can give you a heart problem.
