If you find yourself waking up around 3 a.m., you might blame a restless mind—but there’s often a biological reason behind it. Dave Asprey, a prominent health advocate, explains that nighttime blood sugar drops cause the body to release stress hormones, which can wake you up.
Cortisol and adrenaline release sugar stored in the liver to fuel the brain, but they also raise alertness and interrupt sleep. Normally, cortisol decreases at night to let you rest, but if it remains high, it can cause early waking and difficulty falling back asleep.
A helpful trick is to eat a small snack before bed, such as raw honey, collagen, or MCT oil, which helps keep your blood sugar steady through the night, preventing the hormone surge that disrupts sleep.
Alongside diet, creating a sleep-friendly environment is important: use blackout curtains, reduce noise, keep the room cool, avoid caffeine and alcohol later in the day, and limit devices that emit blue light. Stress-reducing techniques such as meditation or deep breathing also support better sleep.
With these lifestyle changes, you can reduce those annoying 3 a.m. wake-ups and enjoy a more refreshing night’s rest.
