I have always been a "cold" person. I am the person who carries around a light sweater in the summer - I usually can't take the air conditioning system. Until just recently, I was sleeping with socks on - which a lot of people think is weird. I'll tell you why I sleep with socks on - and it will all make sense. When I was a small child I was bitten on my right foot by a spider in bed and my foot became infected. I can only really recall soaking my foot each day and having a lot of pain! So, ever since the spider bite - I have slept in socks. Makes sense, right?
Now, noway! I am so hot at night (and in general) - it's unbelievable. It's still pretty cold here in Chicago with a winter snow storm and I am sleeping in Summer Pj's and a sheet. It's totally unlike me. The feeling "warm" in pregnancy finally hit me. At times when I am on the subway, I am just waiting for my stop because I feel like I am baking myself in all my winter gear. I have even started turning on the air conditioning at work and it's 33 degrees outside!
I have been drinking a lot of cold water, and that helps. I also found that an ice pack on my neck or forehead if I can't sleep- makes all the difference in the world.
