My 96 Camry is overheating and the windshield is usually foggy what's the problem

What is your question?

My 96 Camry is overheating after about 15 or 20 mins of use about every 3 days of daily use. It isn't used to travel long distance just around town to run errands and store trips. I've noticed that the windshield starts to fog up right before it starts to overheat and stays foggy for the remainder of the time. I can't seam to find the issue on my own can someone help. As for noises I'm not hearing anything significant but the car is leaking fluids..I use a gallon of antifreeze daily and I do run the air conditioner too.

What makes this problem better or worse?

Car on while in park makes it worse or a consistent drive of more than 45 mins
