Acute Fog Protocol
When fog hits, try these in order:
- Drink 500ml water — Dehydration mimics cognitive decline
- Walk outside 10 min — Movement + light + fresh air
- Cold water on face/wrists — Activates vagal tone
- Box breathing: 4-4-4-4 — Inhale 4s, hold 4s, exhale 4s, hold 4s
- Protein snack — Blood sugar crash causes fog
Emergency Red Flags
Seek immediate medical attention if:
• Sudden onset of confusion (hours/days)
• Fog + worst headache of life
• Fog + weakness one side of body
• Fog + vision changes or slurred speech
• Fog + fever + stiff neck
• Rapid cognitive decline over days/weeks
