Why Summer Is a Critical Season for Diabetes Management
Summer heat and humidity can be more than just uncomfortable—they can be dangerous for people with diabetes. Dehydration from excessive sweating can lead to high blood sugar levels, while heat can affect insulin effectiveness and increase the risk of hypoglycemia or diabetic ketoacidosis.
Real Case:
Mr. Kim, a 62-year-old man with well-controlled diabetes, experienced dizziness and cold sweats while walking outdoors during a heatwave. Upon arriving at the clinic, he was diagnosed with dehydration and hypoglycemia. After receiving IV fluids and glucose, his symptoms improved. This example highlights the importance of proactive summer blood sugar management.
5 Key Summer Tips for Managing Diabetes
✅ 1. Stay Hydrated
Increased perspiration during summer can lead to dehydration, which thickens the blood and raises glucose levels.
Tips:
-
Drink at least 8 glasses of water daily.
-
Avoid sugary drinks like soda or juice.
-
Carry water with you when going outdoors.
-
Don’t wait until you feel thirsty—drink throughout the day.
✅ 2. Check Your Blood Sugar More Frequently
In summer, blood sugar fluctuations can become more unpredictable.
Tips:
-
Check before and after meals.
-
Monitor before and after physical activity.
-
Keep a log of your readings to detect patterns.
✅ 3. Adjust Exercise Timing
Exercising during hot weather increases the risk of overheating and hypoglycemia.
Tips:
-
Exercise early in the morning or after sunset.
-
Wear breathable, light-colored clothing.
-
Carry fast-acting carbs like glucose tablets or crackers just in case.
-
Avoid outdoor workouts when temperatures exceed 30°C (86°F).
✅ 4. Eat Regularly, Even If You Lose Your Appetite
Skipping meals during summer may lead to low blood sugar episodes.
Tips:
-
Stick to a regular meal schedule.
-
Choose light, balanced meals including whole grains, vegetables, and lean proteins.
-
Limit cold high-sodium foods like instant noodles or pickled items.
✅ 5. Store Your Medications and Insulin Properly
Heat can damage insulin and other diabetes medications, reducing their effectiveness.
Tips:
-
Store insulin in a cool place (2–8°C / 35–46°F).
-
Do not leave medication in a hot car or direct sunlight.
-
Use an insulated pack when traveling.
