They are crepuscular rather than nocturnal, which means they can nap during the night and also the evening and aren't strictly asleep all day and awake all night. However with the lighter nights, hamsters often start coming out earlier and being more active, so if it seems out of character, then as Ruth says, do check if everything is ok. She is not old and they are often still very active at that age.

However their lifespan for old age can be from 18 months to 2 years and it may be she has some ailment that needs checking out. When she does wake up and come out, does she seem well and active? Bright eyes? Alert. If so I shouldn't worry too much.

Check things like water bottle letting out water ok - to make sure she isn't dehydrated. Maybe give her a checkover as well. Female hamsters can get Pyometra - an infection of the womb. That would usually have signs like a discharge or bleeding.

I do think you can get lazy hamsters though! Our last Syrian was a real home-bod lazy sleepyhead!
