To live a healthy life, whether we apply it in our lives or not, the importance of exercise we all know it.

The long-term effects on our overall health and longevity are undeniable, but “Nothing will happen if I stay inactive for a few days.” we can say. Astronauts can’t do this. They MUST exercise regularly.

Exercise on Earth is not the same as exercise in space.

Every time we move on Earth, gravity creates resistance against the muscles and bones in our bodies. So we practice without even realizing it. This way our body stays stronger.

But things change when microgravity in space is taken into account. Bones and muscles do not support the astronauts’ body weight. Even Even the cardiovascular system becomes lazy because the heart doesn’t have to work as hard as it does on Earth to resist gravity and pump blood.

When astronauts in space don’t exercise, their bone density, muscle mass and cardiovascular health weaken.

Despite a rigorous exercise program, experienced astronauts On average 1% of bone density in 1 month they are losing. The average person in the world loses 1% of their bone density per year.

The longer astronauts stay in space, The more important the effects on their body become.

Astronauts who live and work on the International Space Station (ISS) for several months are particularly affected and are on a long-term mission. about two hours a day They have to exercise.
