You’ve finally got the hang of your CGM – tracking glucose, syncing apps – and then comes the next question: Can I actually sleep with this patch on?
Yes, you can – and you should. Your CGM patch is there to protect your sensor during everyday life, and that includes sleep. But to make sure it stays in place overnight (and doesn’t leave you peeling it off at 3am), you’ll want to follow a few simple steps for comfort and secure wear.
This guide will walk you through what happens to your CGM patch while you sleep, how to prep your skin, and what products work best to keep things stuck and stress-free.
What Happens to Your Patch Overnight?
When you're asleep, your skin’s doing more than you think:
- Shifting and flexing with each movement
- Generating heat and moisture, especially under blankets
- Rubbing against fabric from clothes or bedding
- Taking pressure if you lie on your CGM side
Without the right adhesive or prep, even the best sensor can start to lift or come off early.
Top Tips for Sleeping with a CGM Patch
1. Choose the Right Patch for Your Device
Whether you're using a CGM or infusion set, your patch needs to be soft, flexible, and stay put through the night. That means no stiff corners or plastic feel – just breathable, skin-friendly fabric.
At Type Strong, we offer options for:
- Dexcom G7 Patches (20 Pack)
- Dexcom G6 Adhesive Patches
- Freestyle Libre Patches
- Medtronic Guardian
- Infusion Set Patches
- Omnipod Patches
- Tape Roll (Cut to Fit) – great for edge support or custom layering
All are designed to last 10+ days, even through sleep and showers.
2. Apply It Before Bed – But Not Right Before Sleep
What does that mean for your patch? Apply it at least one hour before sleep, giving it time to fully bond with your skin. And avoid applying to sweaty, damp, or recently moisturised skin.
3. Use Skin Prep Wipes (If Needed)
If your patch tends to peel or if you’re a warm sleeper, try prepping the area with a barrier wipe – just make sure it’s completely dry before patching. This can reduce early edge lift and give your patch better grip overnight.
4. Reinforce with Tape for Security (if Needed)
Some users choose to add a bit of cut-to-fit tape to reinforce the edges – especially if they sleep on the same side as their CGM. This helps reduce snagging or edge lift during movement.
5. Sensor Placement Can Affect Sleep Quality
If you often lie directly on your CGM and it causes discomfort or loosens the patch, consider switching sides for your next insertion. Always follow your device’s placement guidelines and avoid areas with bending, friction, or tight clothing.
Quick FAQs: Sleep + CGM Patches
- Can I sleep on the side with my CGM? Yes, but if the pressure bothers you or causes edge lift, reinforce the patch or consider switching sides.
- Why does my patch keep peeling off by morning? Check your prep: skin should be dry and clean. Avoid placing the patch where the skin folds or sweats heavily.
- Is it okay to double-patch or tape over the patch? Yes – just use breathable, medical-grade tape like our cut-to-fit roll. Avoid creating bulk that pulls during sleep.
Universal Sleep Tips for All CGM Users

- Change patches during the day, not just before bed
- Avoid applying lotion near the patch site before sleep
- Use a body pillow to relieve pressure on your sensor side
