i have my 4x4 tent in my bedroom right up against my window to exhaust it out the window somewhat and yea it's healthy only thing bad about it is the damn fan is loud and i have to crank mine up at max speed. my fan is only 4" i should upgrade it probably to a 6" at least or 8" but other then the noise of the fan i don't really have any major issues that solely can be blamed on the tent. humidity sure but i live in Hawaii it's ALWAYS humid here only time i really feel it is when i open up the tent you can feel the hot air but that was back when i didn't vent it out as much now i vent it out as much as i can got everything wide open besides the doors.
biggest concern would be doing your measurements making sure everything fits in your room and where you plan to leave it and access it and if your happy with your bedroom layout. i had the hardest time doing mine due to my 55gal aquarium and ceiling fan but since i really don't care what my room looks like i make it work my layout is decent kind of tight but i have to keep a lot of my gardening shit in my room because my grandpa throws my gardening shit away if i leave it in the garage just my vermicompost going on.
i don't exhaust my tent into my room cause if i did it would be much hotter despite the outside air is cooler then inside plus i only have 1 fan setup. i'd literally need to run an AC to properly drop temps for growing needs but other then that you get used to it. i like the noise tbh cause it helps me sleep at night i tend to keep my computer running all night with something on youtube since i don't have cable in my room
i used to grow in my bedroom closet before i got the tent but without a fan. that was kind of hell because the lights is just shining in my face all the time and i didn't really have a exhaust i used a air purifier for air circulation and that thing is just as loud as my AC infinity
