Heat messes with me all the way around lately, and we (southern California) haven't been tested as badly as the east coast has (yet). To avoid a hospitalization, Hydration is KEY. Also, avoid heavy meals and soda--these tend to be high in salt/sodium and will sap your hydration, affecting your entire body's functions.

Heat really makes things harder for me that is for sure. this summer has been insanity

I never thought about it as until April I have worked in both all four seasons. I am now a stay at home wife and being in south California I have noticed my morning numbers are horrible. But getting out and moving around brings them back down. I have been walking 2-4 miles a day for the last couple weeks now.

I live somewhere were pretty much everyone has central air now. My sugars do run a little higher in summer because watermelon is in season and I eat more of it than I should. When we lived in Oregon though, we did not have air conditioning and If it got over 95, I would turn into a total sloth. For me it may be the total lack of activity, that drives it up during heat.

Heat affects my numbers. i agree that dehydration occurs more readily which negatively impacts bg numbers
