These groups currently recommend seven to nine hours of nightly sleep for healthy adults. The National Heart, Lung and Blood Institute recommends seven to eight hours, including the elderly. Most current guidelines say school-age children should get at least 10 hours of sleep a night, and teenagers, nine to 10. This question really has two parts to it. First, yes, adult humans are supposed to sleep straight through the night. It is clear that 8 hours of continuous sleep is more restorative than 8 hours broken up into separate times over a twenty four hour period (sometimes referred to as "poly-phasic sleep"). Older adults, typically after 70+ years, will begin to become poly-phasic sleepers again. If you sleep 8 hours/night but are still sleepy during the day, you may not be fulfilling your nightly requirements (or may have a co-existing sleep disorder). Current data suggests that getting your sleep in one long stretch results in better sleep quality than getting your sleep in short stretches even if the number of hours spent sleeping is the same. On average humans tend to sleep between 6.5 and 8.5 hours.
