Earlier this month, Duke-NUS Medical School researchers were featured in a first-of-its-kind study in the United States journal Sleep.
In the study, 56 teenagers, mostly from "elite" high schools and aged between 15 and 19, stayed in a boarding school for two weeks to assess how insufficient sleep could affect cognitive function.
For seven nights, half the teens received five hours of sleep, while the other half had nine hours - the recommended sleep duration for this age group.

While it is well documented that sleep deprivation leads to short-term memory loss, it had been believed that it was the result of the brain not being able to assemble and "file away" the information it received in its proper place. However, researchers from the Duke University-NUS Graduate Medical School suggest that the problem occurs earlier in the information-gathering process....

The later Tim Harris stays up playing poker, the bolder — and more imprudent — he becomes. As it turns out, it’s not just Harris choosing risky options when exhausted.
