The usual suspects
Post-prandial dip is real, but rarely the whole story. Insulin sensitivity, sleep debt, caffeine timing, hydration, and cortisol rhythm all contribute.
The seven drivers
1. Sleep debt over the prior week. 2. High-carb low-protein lunch. 3. Late-morning caffeine wearing off. 4. Dehydration. 5. Sub-optimal vitamin D. 6. Low free testosterone. 7. Cortisol dysregulation from chronic stress.
Frequently asked questions
- Will more caffeine fix it?
- Short term yes, but it deepens the sleep debt that drove the crash. Address the cause.
- Is a nap useful?
- 20-minute naps before 3 PM can be excellent. Longer naps disrupt nighttime sleep.
