Compared to people who said on the questionnaires that they got 7 or 8 hours of sleep every night, people who averaged less than 5 hours or more than 8 hours of sleep at night had significantly higher levels of hemoglobin A1C in their blood, reflecting poor blood sugar control over the past 2 or 3 months.

Does sleeping make your blood sugar go up?

Blood sugar levels surge while you're sleeping, usually around 4 to 8 a.m. for someone with a normal sleep schedule. (It's called the dawn effect.)

What foods to avoid if your A1C is high?

How much can A1C drop in 2 months?

If you, from one day to the next, decreased your daily average blood sugar from 300 mg/dl (16.7 mmol/l) to 120 mg/dl (6.7 mmol/l), your A1c would decrease from 12% to 6% in around two months.
