MedCram Episode 140. Flu Deaths Predictable Every Year
Jan 18, 2026
Flu deaths follow a predictable pattern each year, with peaks influenced by seasonal factors like temperature and holiday gatherings. The discussion highlights unique trends, such as Australia's winter peaks and Singapore's lack of seasonality. A strong correlation between sunlight exposure and reduced flu incidence is explored, alongside findings linking higher solar radiation to lower COVID-19 mortality rates. Lesser-known treatments like N-acetylcysteine are also suggested as potential protective measures.

Episode notes
Predictable Seasonal Peak In Winter Deaths
- Influenza and many other causes of death reliably peak 1–3 weeks after the year's shortest day.
- Seasonal timing, not social gatherings, explains consistent winter spikes in deaths.
Hemisphere Phase Shift Disproves Holiday Theory
- Southern Hemisphere flu seasons peak 6 months out of phase with the Northern Hemisphere.
- This mismatch undermines the idea that holidays alone drive seasonal influenza patterns.
Latitude And Sunlight Explain Seasonal Patterns
- Locations near the equator lack clear seasonal flu peaks because solar variation is minimal.
- Latitude and sunlight exposure tightly correlate with seasonal infectious surges.
