Being more specific, if you’re traveling at a speed at which 1 year for you is 10 years on Earth, would your body age 10 years? Why or why not?

Your body would age at the rate time is passing for you. Earth time isn’t some definitive time reference. If it’s 1 year for you then your body ages for 1 year regardless of how much time passes in any other reference.
Time always passes for you at 1 second per second. How much time passes at another location is irrelevant for your question.
The answer to your question is you would age by 1 year as that is how much time passed for you.
No you experience time according to your own reference frame so if only a year passes for you then you only age a year. Other reference frames don’t affect your own even if thousands of years pass in a different one. If you only experience one year of time passing then that’s how much you age.
So this is time dilation. So we’ll go into the tool box and get some identical twins.
Twin 1 stays on Earth.
Twin 2 gets on a light speed rocket where the time dilation is 10:1.
When this starts They are both twenty years old.
Ten years pass on earth. Twin 1 is now 30 years old. Twin 2 lands their ship and they are 21 years old.
Yeah, time dilation is kind strange.
Your body would only age 1 year in this situation. Time is passing slower for everything that is traveling with you. This includes your spaceship, the food you brought, and the cells in your body. You would only age 1 year because this is the amount of time your body experiences. If you travel in a big loop and come back to Earth, you would be 9 years younger than everyone that stayed on Earrh.
No, you would by all measurments experiance 1 year of time. Its because actual physics experiance time dalation. But from your perspective everything will be normal.
Can watch this vid to understand how that happens

Yes, but It would be the other way around, you would look younger, only a year would pass in your body.
Time is the same, it’s how you feel it that makes the difference, that is “relativity”
Your body would age 1 year because one year for you is one year of your body doing stuff and existing.
Space and time are actually just two aspects of the same thing, spacetime. So when you move through space you also move through time, and if you are moving at a some speed compared to someone else you also move through time differently. Wherever you are time is always locally passing at the normal rate, everything feels normal, but for someone in the Andromeda galaxy they will be counting off the seconds at a different rate because they are moving towards us.
If you’re moving at light speed, you age at light speed. If you’re moving at Earth speed, you age at Earth speed. There’s no one universal speed at which time flows anymore than there’s one universal speed that cars move at.
Time is what clocks measure, and aging is a kind of biological clock. You’d age 1 year, because that’s the amount of time that would pass in your reference frame.
You only ever experience time normally in your own reference frame. Your body doesn’t “know” how much time is passing elsewhere. If you are holding a clock and 1 hours ticks, you’ve aged 1 hour. If you hold that clock for 10 years, the clock will show 10 years have passed and you will have aged 10 years.
