THE HOPEFUL HORIZON
- Vaccination reduces sleep sequelae risk by 20-40% (OR 0.6-0.8)[8]
- 60-70% of acute sleep disturbances resolve within 2-4 weeks[22]
- CBT-I shows 60-70% significant improvement in post-COVID insomnia[24]
- Many sleep architecture abnormalities gradually normalize over 6-18 months
