quote: The climate in which you live can make a substantial difference in the frequency and severity of your attacks. Hot, humid weather in particular is actually a stress factor in and of itself, because 1) heat stresses the body, and 2) air pressure changes from humidity affect the levels of serotonin in the body (and over 90% of that serotonin is in your gut), which in turn reduces your pain tolerance level. You may also find that, personally, some types of weather just stress you out and make you depressed, irritable, or unhappy. It doesn't matter if your preferences seem typical or even logical (maybe you hate blue skies and love drizzle) - what's important is that you consciously note your feelings and physical reactions so that you can deal with them.
