Navigating Hot Weather With Diabetes: Tips and Tricks 

When the temperature rises, it’s important for everyone to stay cool. But for people with diabetes, beating the heat is even more crucial. Hot weather can affect your diabetes management, including how your body uses insulin, how you store your equipment, and how you keep track of your blood sugar levels.  

Here are some tips to manage your diabetes in hot weather, helping you to stay safe while enjoying the summer!

1. Keep Your Devices and Insulin Cool 

Diabetes management often involves devices like insulin pumps and continuous glucose monitors (CGMs), as well as insulin medication which can be sensitive to high temperatures. 

Insulin Storage: Insulin should be kept cool to work properly but don’t put it directly in ice or in the freezer. Use a cool bag or an insulated pouch to keep your insulin at the right temperature when you’re on the go. If you get your insulin delivered to your house, always make sure that it comes in a cold package and check the temperature of vials/pens.

Device Care: High temperatures can affect the adhesive that keeps devices like continuous glucose monitors and insulin pumps attached to your body. Try to keep these devices shaded and consider using medical adhesive reinforcement patches to help them stay secure. Test strips for your blood sugar monitor can be affected by the heat, as well. It’s always best to not leave them in a hot temperature vehicle and rather, keep them in a shaded area. 

2. Stay Hydrated 

Drinking plenty of water is key in hot weather, especially for people with diabetes. Dehydration can cause blood sugar levels to concentrate and rise, making diabetes harder to manage. 

Tip: Carry a water bottle with you at all times and sip regularly, even if you don’t feel thirsty. 

3. Monitor Your Blood Sugar More Often 

Heat can make your blood sugar levels more unpredictable. It’s important to check your blood sugar levels more frequently when it’s hot, especially if you are spending a lot of time outdoors or being active. 

Why It Matters: Knowing your blood sugar levels can help you make quick adjustments to food, activity, or medications.

4. Manage Your Meals 

What you eat also plays an important role in managing your diabetes in the heat. 

Eating Tips: Opt for lighter meals that don’t require a lot of digestion, which can raise your body temperature. Fruits and vegetables are great because they can also help keep you hydrated.

5. Dress Appropriately 

Wearing the right clothes can help you stay cool and manage your diabetes. 

Clothing Choices: Choose lightweight, loose-fitting, and light-colored clothing that reflects the sun’s rays rather than absorbing them. Don’t forget a wide-brimmed hat and sunglasses for extra protection.

6. Know the Signs of Heat Exhaustion 

Heat exhaustion is a serious risk in hot weather, especially for people with diabetes. It can lead to heat stroke, a life-threatening condition. 

Symptoms of Heat Exhaustion include heavy sweating, weakness, cold, pale and clammy skin, fast or weak pulse, nausea or vomiting, and fainting. If you experience these symptoms, move to a cooler place, stop all activity, and sip water. Seek medical help if symptoms worsen or last more than an hour. 

Keep it Cool 

Hot weather can pose additional challenges for managing diabetes, but with the right preparations and precautions, you can enjoy the warm days safely. Remember to consult with your healthcare provider for more personalized advice based on your specific health needs.
