Waking up at 3 a.m. often signals low blood sugar

Many people wake up at 3 a.m. regularly, often due to low blood sugar. Sleep specialist Michael Breus notes that after several hours without food, cortisol levels rise, causing hunger and waking individuals up. Waking up at night is common, with over a third of people experiencing it. While anxiety and stress can contribute, consistent wake-ups may indicate low blood sugar as a specific issue. To prevent waking up, Breus suggests adjusting meal times. A small snack before bed can help maintain blood sugar levels overnight. Those with diabetes or similar conditions should consult a doctor for tailored advice.
