Blood sugar is usually the culprit
A carb-heavy lunch with little protein, eaten in front of a screen, sets up the classic post-lunch crash. Insulin spikes, glucose drops, and energy bottoms out 90 minutes later.
The 4 fixes
1. Build lunch around 40g of protein. 2. Walk 10 minutes after eating. 3. Cap afternoon caffeine at 2 p.m. 4. Get 10 minutes of outdoor light in the early afternoon.
Frequently asked questions
- Is a quick nap better than caffeine?
- A 15–20 minute nap before 3 p.m. usually restores afternoon performance better than another coffee — without the evening sleep cost.
- Why does sugar make the crash worse?
- Sugar drives a larger insulin spike, which produces a larger reactive low 60–90 minutes later.
