When temperatures rise, keeping diabetes in check can be more difficult because high temperatures change the way your body uses insulin. Fortunately, there are steps you can take to manage your diabetes when the heat is on. 

When you’re heading outside:

• Wear sunscreen and a hat. You want to avoid getting sunburned, since it can raise your blood sugar level.
• Wear loose, lightweight, light-colored clothing.
• Protect your feet. Don’t venture out in bare feet as this could result in burns or serious infections.
• Avoid being outside during the hottest times of the day.
• Check the heat index — a measurement that combines the temperature and the humidity. The more humid it is, the harder it is for your body to cool down. 

When you’re exercising:

• Test your blood sugar before, during, and after being active.
• Go out early in the morning or in the evening when temperatures are lower; or head to an air-conditioned place, such as a mall or a gym, to be active.
• Drink lots of water. People with diabetes tend to get dehydrated more easily. Keep water on hand when you’re active, as well as when you’re not.

When you’re managing your blood sugar:

• Test your blood sugar often when temperatures are high.
• Never keep medications in a hot car or in direct sunlight. Check the package instructions to find out the optimal temperatures to store your medicines and testing supplies.
• Be prepared for emergencies. Have an emergency bag and a plan in case you lose power.
