Sweaty days, ocean swims, and long hours in the sun: summer is full of activity, but it can be a challenging time for those wearing Continuous Glucose Monitors (CGMs). Heat and moisture can weaken the adhesive that keeps your CGM secure, leading to peeling edges or even lost sensors.

Understanding how to maintain your CGM in warmer weather can make all the difference. Sweat is one of the main culprits, especially during workouts or outdoor fun. It seeps under the sensor adhesive, loosening the bond with your skin. Chlorinated pool water and salt from the sea can have a similar effect.

Wearing an overpatch is a simple and effective solution. The added layer helps protect your sensor from sweat, water, and friction caused by clothing or movement. The best patches offer flexibility, breathability, and skin-friendliness while still staying firmly in place for days.

Another tip: make sure your skin is clean and dry before application. Oils, lotions, or sunscreen residue can affect how well adhesives stick. Some people find it helpful to apply their CGM and patch in the evening when the skin is cooler and drier.

Summer doesn’t have to mean sensor anxiety. With the right support, it's easy to stay active and confident, no matter how high the temperature climbs.
