Hot Weather and Your Diabetes
During the heat of the summer, it is important to consider that the ambient temperature will affect your diabetes management.
- Heat can affect your blood glucose (sugar) levels and also increase the absorption of some fast-acting insulin, meaning you will need to test your blood glucose more often and perhaps adjust your intake of insulin, food and liquids.
- Drink plenty of fluids, especially water, to avoid dehydration. Drink a glass of (sugarfree) fluids before going outdoors and at least ever half hour when outdoors in temperature above 80 degrees F. If your doctor has limited how much liquid you can drink, ask what to do during times of high heat.
- Check package inserts with medications to learn when high temperatures can affect them. Take medications with you if you will need to take them while you’re away from home, and protect them from the heat.
- Remember not to leave your blood glucose meter, insulin, or other injectable medications, in direct sunlight or in a hot car. When travelling, keep your medications in a cooler but do not place it directly on ice or on a gel pack.
- Heat can damage insulin pumps and other equipment. Do not leave the disconnected pump or supplies in the direct sun. Perspiration can affect the sticking quality of your patches.
- Get physical activity in air-conditioned areas, or exercise outside early or late in the day, during cooler temperatures.
- Beware of the major changes in humidity and temperature when travelling and then exiting a car.
- Always wear your medical ID! Always!
