wear more clothes to keep warm.

does the rest of where you live have heat? If so I'd imagine the sun heat is negligible and it's better to keep the heat from your house inside. why don't you get a space heater?

I used to work for a window company. You will definitely be losing more energy from a window that is leaking air than you will gain heat from the sunlight. Try re-caulking the window. That will help a little, but if your window is warped then that will only do so much. If youre a renter your landlord has to replace your window if it is in this condition. If they don't you can contact a lawyer and they will probably tell you that if they don't you can replace it yourself and deduct the cost from your rent.

Put the styrofoam up when the sun sets and take it down when the sun rises.

It's just that the glass is cold. It leaks from under the window, but I can put some towels or clothes there.
