PS4 rest mode or turn it off ?

So i just bought a new PS4 ( i know its outdated because of releasing of PS5 but i can’t afford it ). and i was wondering if i always keep it on sleep mode/rest mode. Isn’t its damage his parts ?, like IC, controller, disk plate ?
If you keep it rest mode, how long? Forever?

Well first PS4 isn’t outdated yet, since Sony is still releasing new games for PS4. Talk about sleeping mode, well i heard it’s not good to turn off and on all the time.

I put my PS4 in sleep mode/rest mode so i it can install games,updates and make it ready for me when i come back. Its been a year since i am doing this thing so i don’t see any problem during these time of period
