Why We Might Not Need Eight Hours of Sleep After All
The Evolution of Sleep Norms
Unpacking the historical context of sleep, it's fascinating to see how the rigid eight-hour sleep cycle emerged during the Industrial Revolution, a period marked by long, grueling work hours. The idea was more about aligning the workforce to a schedule conducive to mass production than actual health needs.
Rethinking Sleep Duration
Current research suggests that the optimal nightly sleep for many healthy adults hovers around seven hours. While this may seem surprising, it aligns with evolutionary biology studies indicating that our ancestors didn't sleep in one continuous eight-hour block.

Exploring the U-Shaped Risk Curve
The notion of a U-shaped risk curve is gaining traction among scientists. Essentially, both too little and too much sleep can be detrimental to health. Research links these extremes to various health issues, reinforcing the idea that striking a balance is key.
Key Takeaways from Sleep Studies
- Most adults thrive on 6.5 to 7.5 hours of sleep.
- Quality of sleep is as crucial as quantity.
- The sleep needs of individuals can vary widely based on lifestyle and genetics.
