How to Clear Afternoon Brain Fog and Improve Focus
Brain fog and afternoon sluggishness make even routine work feel exhausting. Getting back your mental sharp edge requires addressing hydration, blood sugar stability, and focused work blocks.
1. What Triggers Brain Fog?
Common everyday culprits include:
- Post-lunch blood sugar spikes: High-carb lunches cause a rapid glucose rise followed by an energy crash.
- Dehydration: Mild fluid loss directly impairs concentration and memory recall.
- Digital overload: Constant task-switching drains cognitive energy reserves.
