The human body evolved for that, and much more, you're not training 90 min per day at athlete level performance, you'll be fine... Of course if you run 10 hours per week with bad technique you're going to fuck your shit up, but you can easily alternate 60 min of gym/cardio every day with very little chance of injuries + an evening 30min "brisk" walk or 30 min of bicycle commute.
It's your body, do as you want, but chances are you exercise (way) too little, not too much
