Summertime Tips and Tricks for Diabetics

Diabetes affects more than 40 million Americans, with an estimated 1.5 million new cases diagnosed annually. This chronic condition occurs when your body is unable to either produce or process insulin efficiently, leading to dangerously high blood sugar (glucose) levels.

Physicians Alejandro Blanco, MD, and Ralph Rodriguez, MD, lead the team at Internal Medicine Partners in Naples, Florida, providing comprehensive medical care for diabetes and diabetes-related complications. We work with you to develop personalized solutions that keep your glucose levels stable and your long-term wellness on track.

In a healthy body, the heart pumps blood toward the skin, and the blood vessels dilate (expand) to let heat escape. But because sustained high blood sugar can damage the nerves and blood vessels responsible for this cooling process, the risk of heat stroke becomes much higher with diabetes. 

Read on as we share our expert tips and tricks for staying healthy in the heat and humidity.

Make hydration a priority

High temperatures and humidity can lead to rapid fluid loss, which is particularly dangerous for those with diabetes. When you’re not drinking enough, glucose becomes more concentrated in your bloodstream, resulting in higher readings and an increased risk of further dehydration.

To stay ahead of the heat, drink water consistently throughout the day — don’t wait until you’re thirsty. Avoid sugary drinks and caffeine, which can spike blood sugar and increase fluid loss. Instead, opt for water or sugar-free electrolyte drinks to stay hydrated while keeping your blood sugar in a healthy range.

Protect your medications and equipment

Extreme heat can damage your diabetes medicine and equipment, potentially affecting the accuracy of your readings or the effectiveness of your treatment. Insulin, in particular, is highly temperature-sensitive and can lose potency if exposed to direct sunlight or left in a hot car.

If you’re travelling or plan to be outside for an extended period, consider using an insulated bag or specialized cooling case to protect your supplies from the hot summer sun.

Adjust your workout routine

While regular exercise is a key part of managing diabetes, an outdoor workout or activity that feels manageable in the fall or winter could lead to unexpected hypoglycemia (low blood sugar) during the summer months. 

High temperatures speed up the body’s absorption of insulin, causing blood sugar to drop rapidly — especially during physical activity. To stay safe and active, plan your outdoor activities for the early morning or evening when the UV index is lower, and always check your levels before and after exercising.

Practice proper foot care

Over time, high blood sugar can cause nerve damage — known as diabetic neuropathy — that leads to a loss of sensation in the feet. Because you may not feel them, small cuts and injuries easily go unnoticed and develop into serious infections or ulcers.

When you live with diabetes, protective footwear is a necessity at all times, even at home and on the beach. Make it a habit to perform a daily foot check, looking for any redness, blisters, or swelling that may require professional wound care.

Recognize the signs of heat exhaustion

High temperatures put extra stress on your body, and the symptoms of heat exhaustion often mimic those of hypoglycemia. If you’re experiencing dizziness, heavy sweating, and/or confusion on a hot day, checking your glucose levels is the only way to identify the source of your symptoms and determine the right course of action.

Should your readings come back within a normal range but you still feel overheated, move to a shaded or air-conditioned area immediately to cool down and rehydrate.
