Multiple Choice

The cognitive impairments from sleep restricted to six or fewer hours per night for one week are equivalent to how much total sleep loss?

When you restrict sleep to six hours or less for seven consecutive nights, you accumulate a sleep debt compared with a typical 8-hour baseline. That weekly restriction adds about 14 hours of lost sleep (7 nights × ~2 hours per night). That amount of debt is best described as being equivalent to missing roughly one to two full nights of sleep, which is why the correct choice is one to two nights. The other options would require more sleep debt (zero would be no debt; three to four or five to six nights imply 24–48+ hours of lost sleep).
