Summer is a time for sunshine, vacations and outdoor fun. However, a few challenges when it comes to managing your glucose levels with a continuous glucose monitor (CGM) may arise.
Whether you’re hitting the beach, hiking new trails or simply enjoying the warmer weather, here are some summer tips for CGM users to keep the device functioning properly.
1. Beat the Heat: Protect Your Sensor and Transmitter
CGMs are sensitive to high temperatures, and prolonged heat exposure can impact sensor accuracy or battery life.
Tips:
-
Avoid direct sunlight on your sensor or receiver for long amounts of time.
-
Store your CGM receiver and supplies in a cool, shaded place (a small insulated pouch can help).
-
If you’re leaving devices in a hot car, think twice. Even a few minutes in a parked vehicle can overheat your equipment.
2. Stay Stuck: Make Your CGM Adhesive Summer-Proof
Sweat, water and sunscreen can loosen adhesives, especially during humid or active summer days.
Tips:
-
Use skin prep wipes before applying your sensor.
-
Consider adhesive overlays or patches for extra staying power.
-
Let your sensor site dry thoroughly before swimming or heavy activity.
3. Stay Hydrated
Dehydration can affect your glucose levels and make it harder for CGMs to read accurately.
Tips:
-
Drink water consistently throughout the day, especially when it’s hot or you’re more active than usual.
-
Keep electrolyte drinks on hand if you’re sweating a lot (just watch for added sugars).
4. Watch for Glucose Swings During Outdoor Activities
Summer often brings more physical activity, which is great but it can also cause unexpected lows.
Tips:
-
Check your glucose more frequently when hiking, swimming or doing outdoor sports.
-
Carry fast-acting carbs (glucose tablets, fruit snacks, juice) wherever you go.
-
Set temporary activity alerts or adjust your alerts for summer routines if your CGM allows.
5. Travel Smart With Your CGM
Traveling this summer? Be prepared so your CGM doesn’t slow you down.
Tips:
-
Pack extra sensors, chargers and backup supplies in your carry-on.
-
Check airline and security guidelines about CGM devices, most can go through scanners, but it’s good to confirm.
-
Don’t forget power adapters or portable chargers if you’re heading abroad or off the grid.
6. Mind Your Meals and Treats
Summer barbecues and vacations often bring indulgent foods. While it’s okay to enjoy them, be mindful of their impact.
Tips:
-
Pair sugary treats with protein or fiber to help stabilize glucose levels.
-
Use your CGM trends to help guide meal decisions and make smart swaps if needed.
-
Your doctor may discuss the option of a pre-bolus for meals when appropriate, particularly if you plan to eat foods high in carbohydrates.
Your CGM is an incredible tool that gives you more freedom and control, which can be especially useful during the spontaneity of summer. A little preparation can help you stay confident, comfortable and in control while making the most of the season.
With those summer tips for CGM users in mind, you should be ready to soak up the sun. Here’s to sunny skies and steady numbers!
