Managing Diabetes in the Texas Summer Heat:
Tips from Our Home Health Nurses
Extreme heat affects nearly every system in the body — and for the many Central Texas patients managing diabetes, summer brings a specific set of risks that are easy to overlook until they become a problem.
High temperatures can cause blood sugar levels to swing in both directions. Dehydration concentrates blood sugar, pushing levels up, while increased activity, appetite changes, or heat-related illness can also trigger drops. Heat also speeds the breakdown of insulin and certain oral medications, and it can damage supplies that aren’t stored properly — insulin left in a hot car or near a sunny window can lose effectiveness within hours.
Diabetic foot care deserves extra attention in summer as well. Sandals and bare feet — common in Texas heat — increase the risk of cuts, blisters, and burns that diabetic patients may not feel due to nerve damage, and that can be slow to heal.
Our skilled nurses provide hands-on diabetic education and management as part of routine home visits, including glucose monitoring, medication timing, foot checks, and practical strategies for keeping insulin and supplies at safe temperatures during Texas summers.
- Store insulin in a cool, shaded spot — never in direct sunlight or a hot car, even briefly.
- Check blood sugar more frequently on extremely hot days or after time spent outdoors.
- Wear closed, supportive shoes outdoors and check feet daily for cuts or blisters.
- Stay ahead of hydration; water supports more stable glucose control than many patients realize.
- Keep fast-acting glucose on hand in case of a sudden drop during outdoor activity.
