Try to avoid hot, spicy foods, warm beverages, caffeine and alcohol, as these are common hot flash triggers. When choosing clothing in the morning, dress in layers, so you can remove a layer if you get too warm. Pick light, breathable fabrics.
In the U.S., women are held to a thin-ideal or an ideal of body perfection. Not only are women encouraged to be thin, but they have to be thin with curves (i.e., control your weight and change your body structure too!!). Women are bombarded by messages of this perfect and thin-ideal.
If you do holidays in a way that is consistent with what's important to you (e.g., family connection), and not what's important to society (e.g., the perfect decorations, presents, or meal), this will help you eliminate a lot of unnecessary stress.
