What is more important: proper hydration or cooler temperature to reduce nausea in early pregnancy?

Acupuncture is best: I think fatigue has a lot to do with how sick you feel, so i usually recommend sleep. Acupuncture has been shown to help in some good studies, and my patients have done very well with that also. It's always good to stay hydrated, but i haven't heard that helps with nausea in pregnancy. Most pregnant women run hot. I've not heard that cooling affects nausea, but you might feel better overall.
