    Blog: Heat and diabetes

Hi Bloggers,

If you're experiencing hot weather this summer, believe it or not heat doesn't have a direct effect on your blood glucose, but can lead to changes in your daily routine that can affect your blood glucose.

For example, you may eat less or eat more, be more active and/or exert yourself more.

Other considerations in hot weather:

  • Avoid sunburn, it can stress your body and can raise your blood glucose. Wear a good sunscreen, sunglasses and hat when out in the sun.
  • Drink plenty of water to avoid dehydration. Carry a bottle of water with you on walks, etc.
  • Exercise and do more strenuous activities in the early or later hours of the day when the temperatures are cooler and the sun is not at its peak.
  • Whenever your daily routine changes, test your blood glucose more often.
  • Remember, extreme temperature changes can have an effect on your diabetes supplies; insulin can break down in extreme heat, heat and humidity can damage blood glucose meters and test strips, and altitude can affect blood glucose meter performance.

Often, in the summer season, people are more active and insulin requirements change. For example, many farmers with diabetes in our area have considerably lower insulin requirements in the summer months when they are out in the fields vs. the winter months when they are inside and more sedate.

How does the heat affect your blood glucose and how you handle it?

I hope you're having a wonderful summer and I look forward to reading your comments.

Nancy
