Is mountain driving hard on a car?

I do lots of driving up and down mt hood for work but i want to get lots of miles out of my honda will driving up and down mt hood frequently (4-5 times a week) shorten the life of my car? I know it would if i was just up hill it would, but you also go down hill which is low stress. I change the oil every 5k miles and its a 2011 hch btw

Change oil weekly

Downhill is not low stress… Down is higher stress

Should be fine

It is hard on the brakes.
It should be fine on the engine and transmission if thr car is properly designed.
