July brings the heat!  It affects our mood; some people are lamenting the 30-degree weather while others are soaking up the heat like Gila monster in Arizona. Did you know that the heat can affect your blood sugar levels? If you have diabetes, it’s important to know how to manage your blood sugar before spending time in the heat.

So how does heat impact individuals with diabetes? For one, the heat can cause low or high blood sugar. Usually, physical activity causes blood sugar levels to decrease, reducing the need for insulin. However, exercising in the heat may also cause your blood sugar levels to rise.

To prevent this, take extra precautions and monitor your sugar levels before and during exercise.  Additionally, sweating from the heat and physical activity may lead to dehydration, which also means a rise in glucose levels. Adequate hydration can help prevent dehydration.

Extreme heat can also damage your medications and testing equipment. Most types of insulin can tolerate temperatures of up to 93 to 95 degrees Fahrenheit or 33.9 to 35 degrees Celsius. Similarly, testing supplies like test strips are sensitive to heat and moisture. Keep an eye on any insulin and testing supplies you’re carrying with you in the heat.

Finally, hot weather practices such as drinking water, wearing loose-fitting clothing, and paying attention to the weather are also beneficial for managing diabetes. As long as you test your blood sugar levels frequently and protect your medication and supplies, you should be good to have some fun in the sun! Take care of yourselves and each other.
