This planet is so cold and hostile, that your health actually might be threatened. Not really recommended for low levels.
When you land you will end up in the icy plains on Hoth, where the cold itself might affect your hit points, and if not that was enough,
there also are Wampas and imperial probe droid wandering around that will attack you.
But somewhere south/north of where you ship lands, you might
find a hidden rebel base for warmth. There are not many facilities here, but a little shop and a medical station can be found.
Some kind of strange saber is also said to be located inside the base.
Inside the Avenger, that orbits Hoth, you might find a
body glove / unit that can be worn to lessen the effect of the cold on Hoth.
