Most people connect blood sugar solely to what they eat. However, clinical studies show that even a single night of fragmented or restricted sleep can increase morning insulin resistance by up to 33% in healthy individuals.
The Cortisol & Melatonin Tug-of-War
When you enter deep slow-wave sleep, your sympathetic nervous system calms down, growth hormone repairs tissues, and glucose utilization in the brain drops. Sleep deprivation triggers elevated cortisol, signaling the liver to release stored glucose into the bloodstream even when you haven't eaten.
Natural Protocols for Deep Restorative Sleep
- Keep the bedroom temperature cool (65°F to 68°F / 18°C to 20°C).
- Take magnesium glycinate or L-theanine 45 minutes before sleep.
- Eliminate all ambient LED lights and use blackout curtains.
