This study makes me wonder if stress is actually good for my budget (in a very short term, bottom line sense). Certainly I'm not relaxed when I'm stressed, avoiding the 15% over valuation, but I find that when I'm stressed I seek control on any front I can exert it, spending being one that is particularly a crutch for me. I believe I do spend less when I'm stressed and in reciprocal, would spend more when I'm relaxed. However, I don't know the extent to which this is a problem for me since I would say I naturally err on the side of under spending. I would say my greater problem by far is a need for tight control of my spending when stressed.
Do you spend more when you're relaxed? Less when you're stressed? Do you think it should be an area of concern?
