The fun, easy to use multimedia program, "Cycles of Sleeping and Waking with the Doze Family" visits the three-generation Doze family – adolescent, adult, and older adult – to see how each family member's sleep is impacted by his/her daily routine, lifestyle, and age. We see what happens while we sleep, how the systems of sleeping and waking work in everyday life, and how they affect sleep patterns at different stages of life. We also learn about common problems related to getting the adequate and quality sleep essential for optimum heath, safety, and overall well-being.  Check out NSF's interactive 3-D educational tool now!
