What affects my face and it shape? (photo)

I had hyperthyroidism in a bad form. Now the tests are ok. I ended up with lower eye lid retraction (I am thinking to get restylane for that). I noticed, when I sleep with AC on, I wake up looking better, my eye lids are less retracted, my face is tight and even looks skinnier. When I sleep without AC, I wake up with my face looking a bit swallen, eye lids are retracted a lot, and my face looks bigger and more round. What to do about it? What's the cause? I tried cold compress, doesn't work.
