Heat hits us harder

Heat hits us harder.

Summer isn't just uncomfortable when you have diabetes — it can actually move your numbers.

Here's why. Heat and high blood sugar both pull water out of you — more sweating, more trips to the bathroom. And when there's less water in your blood, the glucose in it gets more concentrated. So dehydration can quietly nudge your sugar up — which makes you lose even more fluid. A small loop that builds fast on a hot day.

Two things make it sneak up on us:

Thirst is a late signal. By the time you feel it, you're already behind — and if you have neuropathy, that signal can be even quieter.

Heat is hard on your gear, too. Insulin doesn't like a hot car or a sunny beach bag, and meters and strips have temperature limits. Heat-damaged insulin may not work the way you expect.

Do this tomorrow:

• Keep water within arm's reach — desk, car, nightstand — and sip through the day. Don't wait for thirst.
• Make plain water the default. Sugary and "energy" drinks spike your sugar and work against the hydration.
• On hot days, check your sugar a little more often — heat can move your numbers.
• Keep insulin and your meter out of the heat — never a hot car or direct sun.

LocalDiabetic is being built around simple daily wins like this — a gentle nudge to drink, your readings, and your supplies in one private place, so the small things don't slip on a busy summer day.

The good stuff, no noise.

General education, not medical advice. If you ever feel confused, dizzy, or faint in the heat — or have very high blood sugar with nausea or vomiting — that's an emergency, call 911. Your care team sets your plan, not a newsletter.
