Call it an “oldie but goodie” because the ways in which hot weather can affect diabetes haven’t changed in the last few years and they won’t be changing any time soon…and with summer just around the corner, it’s good to remind ourselves of the extra precautions we might want to take in order to combat the heat. Read on for more on the ways summer weather can affect people with diabetes…
The summer heat seems to be here to stay in Massachusetts. We’ve experienced several weeks of soupy, high-heat weather that *almost* makes me long for cooler, autumnal days…but not quite, because that just means winter (and snow – blech) is right around the corner.
Truly, I do enjoy the summertime. To me, summer is about trips to the beach, ice cream consumption (and lots of it), barbecues with family and friends, long walks in the neighborhood, and endless outdoor adventures. Aside from all of those lovely things, summer also means that it’s time to be a little more diligent when it comes to my diabetes. That’s because hot weather can play some cruel tricks on a T1D’s body. What do I mean by that? Here’s five ways diabetes can be affected by hot weather.
- Dehydration can lead to high blood sugar. Everyone knows that it’s important to stay hydrated when it’s hot out, but it might be less common knowledge that dehydration can directly affect blood sugar. There’s a scientific explanation for this: If not properly hydrated, the body sees an increase in blood glucose concentration because blood won’t flow as easily to the kidneys, making it difficult for the kidneys to get rid of excess glucose in urine. The best way to prevent this, naturally, is to drink plenty of water and monitor blood sugars.
- Sunburn can drive up blood sugars. I’m very familiar with how a sunburn can result in higher blood sugars; in fact, just last week I was dealing with a particularly gnarly sunburn on my thighs and belly that not only made my numbers higher, but also really hurt. My skin was literally damaged, so the stress from the injury lead to retaliation from my blood sugar. Luckily, it only lasted about 48 hours, but those couple of days were challenging as I dealt with sticky highs that were practically resistant to insulin. And for the record, I DID apply sunscreen – numerous times – when I was at the beach. Next time, I’ll seek shade under the umbrella.
- Sweat can make it difficult for devices to stick. I don’t know a single medical device that’s immune to prolonged exposure to moisture/water, but that doesn’t prevent me from spending as much time as I can outdoors/at the beach/by the pool in the summer. Thank goodness for Skin-Tac wipes and medical adhesive tapes that help preserve my precious pods and sensors!“
- Insulin can overheat. There’s a reason why insulin vials come packaged in cartons with directions that specify what temperature insulin should stay at in order for it to be safe to use. Insulin can spoil easily when it reaches a certain temperature, so it’s important to store it in a cool place when the weather’s warm. I alternate between a mini portable cooler (that can hold 3 vials of insulin) and a pouch from FRIO – both do an excellent job at keeping my insulin cool.
- Low blood sugars can occur more frequently. Summertime is prime time for outdoor activities that result in higher energy expenditure. So it’s no wonder that blood sugar tends to plummet in hot weather. Looking at it on the bright side, it’s an excuse to eat even more ice cream – but it also means that monitoring how I feel and checking blood sugars often is that much more important.
Regardless of the diabetes challenges it may cause, I love summer weather, and I know I’ll miss it the moment the first snowflake falls this year.
