Our bodies go through some wild changes when we're out in deep space, it’s like being in a super cold, empty playground where there's no one to play with.
Imagine you’re wearing your favorite sweater on a really chilly winter day. That’s kind of what happens to our skin and blood vessels in space: they get super cold, because there’s almost no air or heat around us. Without that warmth, our bodies have trouble keeping up.
Also, there's less gravity, think about how it feels when you jump on a trampoline. In deep space, your body floats around like that trampoline, so your muscles and bones might get weaker over time, just like if you didn’t play outside for weeks.
And don't forget the radiation, it’s like being under a really strong sun all day every day. It can make our cells tired or even a little damaged. So astronauts have to wear special suits or stay behind shields to protect themselves from that extra sunshine.
In short, deep space is like a big, empty room where your body has to work harder than ever, but with the right help, it can handle it! Our bodies go through some wild changes when we're out in deep space, it’s like being in a super cold, empty playground where there's no one to play with.

Examples
- Imagine floating in a spaceship without gravity, and being bombarded by radiation, that's what astronauts experience every day.
- Your bones might get weaker if you spend years in space because there's no gravity to keep them strong.
- Astronauts sometimes come back from space with swollen faces because of the lack of gravity.
