6 Ways Hot Weather Affects Your Diabetes Management

3. Sweat can loosen adhesive on CGMs and insulin pumps.

If you’re outside in the heat and getting sweaty, the adhesive on your CGM and/or insulin pump could become loose. This may not be the absolute end of the world, but it could definitely be a pain in the neck (or wherever you attach your CGM or pump—we don’t recommend attaching either of these to your neck).

Bring extra adhesive with you when you’re going to be out in the heat, and monitor how well the adhesive you’re using is staying stuck to avoid a potential problem. You might also want to try using an adhesive that is designed to remain sticky when it gets damp.

2. The heat can damage glucose meters and test strips as well.

It’s recommended that you keep your diabetes testing supplies at a comfortable room temperature to keep them from being damaged by the heat, which could potentially yield inaccurate and misleading results. You can cover diabetes supplies with a white towel if they have to be out in the sun.

If you wear a CGM and aren’t able to keep it out of the heat, consider bringing a backup method to check your blood sugar occasionally and make sure the CGM is still working correctly.

1. Summer activities and footwear may open you up to injury.

Going barefoot or wearing flip-flops or sandals increases your risk of foot injury. The tendency to spend more time outdoors during the summer doing activities like swimming, hiking, and camping can also cause you to receive more cuts and scrapes than you ordinarily would.

Because diabetes can make wound-healing difficult (and nerve damage can make you less likely to feel your injury), it’s important to be on the lookout for these issues. Wear protective clothing when you can, check your body over for injuries at the end of every day, and treat any cuts or scrapes immediately to help speed the healing process.


If you have questions or concerns about your safety during hot weather, talk to your doctor about what else you can do to properly maintain your diabetes in these conditions.

If you’re venturing out in the hot weather, remember to bring your sunscreen and water. It may also be a good idea to carry glucose gels and a glucagon kit just in case. Have fun and stay safe out there!
