Introduction
Tamil Nadu’s summers can be brutal and for people with diabetes, extreme heat brings unique challenges. Understanding how heat waves impact glucose control can help you stay safe and healthy.
1.Why Heat Raises Blood Sugar
- Dehydration: High temperatures increase fluid loss through sweat, concentrating blood glucose.
- Stress Response: Heat is a physical stressor. Your body releases cortisol and adrenaline, which can elevate blood sugar.
- Medication Impact: Hot weather can alter how insulin is absorbed or how oral medications are metabolized.
2.Common Symptoms in Heat
- Increased thirst & dry mouth
- Fatigue & dizziness
- Unexpected spikes in fasting or post meal sugars
- Headaches
3.Practical Tips to Keep Levels Stable
Hydrate Often: Aim for at least 2–3 L of water per day. Include electrolytes (no–sugar drinks) if you are sweating heavily.
Check More Frequently: In extreme heat, monitor your glucose every 3 -4 hours, especially before and after outdoor activity.
Adjust Insulin Timing: Talk to your doctor the dose or timing may need tweaking on very hot days.
Stay Cool: Use fans, air conditioning, or cool showers to keep body temperature down.
Wear Breathable Clothing: Light, loose, moisture wicking fabrics help sweat evaporate and prevent overheating.
4.Diet & Lifestyle
- Electrolyte rich Foods: Watermelon, cucumber, coconut water (unsweetened).
- Light, Frequent Meals: Smaller portions reduce post meal spikes and keep you energized.
Conclusion
Heat waves don’t have to derail your diabetes management. With proactive hydration, frequent monitoring, and smart lifestyle adjustments, you can maintain stable glucose levels even when the mercury soars.
