The beach and its glorious sun had an effect on my insulin, after all. My blood sugar levels were running high Sunday and Monday until I changed out my pod and therefore the “less effective” insulin within it. But I learned something else today (thanks to JDRF’s Summer Guide to Type 1 Diabetes):

Unfortunately heat can cause both unexpected highs and lows in blood-sugar levels.

Dehydration is common in the summer and can lead to spikes when blood glucose becomes more concentrated due to the decrease in blood flow through the kidneys.

The heat can also cause dives in blood-glucose levels. As the temperature rises, the body’s blood vessels expand, speeding up insulin absorption and increasing the risk of hypoglycemia. This is especially true while exercising, as working out already increases blood flow.

There are no days off. 🙂
