It's the "dog days" here in Minnesota — the hottest, most sultry days of summer. In the northern hemisphere that's usually July and August. Such heat and humidity affects people with chronic conditions more than it does others.
If you have diabetes, here are some general tips to keep you safe when the weather is at its hottest.
Recognize and treat heat exhaustion to avoid heat stroke
Heat exhaustion symptoms
If you have diabetes, you're at greater risk of heat exhaustion, which occurs when you're exposed to high temperatures for a long period of time and don't replace the fluids you lose. Your body produces more heat than it can release.
Symptoms of heat exhaustion include:
If you experience any of these symptoms on a hot, especially humid day, it's important that you take steps to avoid heat stroke.

Thank you for the concise advice. I suffered from these symptoms as a pre-diabetic but didn't know why. I have printed this and will keep in my purse in case i need to give it to someone. I learned, the hard way, to keep small bottle of water in my purse and often wear a wet cotton scarf when going for walk. I live in Hawaii and stay away from polyester and nylon clothing (mix is okay). And i have told folk coming here, leave your polyester at home. Thanks to the other comments as well. I hope all of you are wearing a medic bracelet or necklace because others won't go through your phone right away.
The Bay Area (California) where I live is pretty cool compared to the rest of the state. ie. today's forcast is for triple digit temps, but we won't get much over 80, if we even get that high. A constant breeze off the bay makes it even cooler at the bayfront park, where I typically do my daily walk.
I really sympathize with those who live in warmer areas. I moved here from Michigan, where 90 to 100 degrees is not unusual, even at the Lake Michigan beaches. I am so glad to be here, where there is no snow and moderate temperatures all year around.
Great advice! I would add to that that I have limited my coffee intake to two a day, and before noon.
Can you explain what appropriate cooling clothing looks like? Does it always have to be cotton? Can a poly blend work too? Is less coverage better or worse? Does a flowing caftan work? How about head cover? Thank You!
Very helpful and concise information.

Small request of a mom of a child with type 1 - please specify type 2 when you are talking about losing weight, etc. Many people offer ignorant hurtful comments about how to "cure" my son's diabetes by getting a gastic bypass, going on a diet, etc. Having said that, many of us have this mentality that we only seek help if we already experience some signs and symptoms. We should take into consideration that type 1 it is not like other disease that can be managed in an instant, rather, it is a lifetime condition to manage.
GREAT safety tips ever! Thank you for sharing this!
Good info. Read this to give a heads up even if you think you know. Inspiration.............
