Sleep Health Index

Sleep Health Index

The Sleep Health Index® is a proprietary tool of the National Sleep Foundation that measures the nation’s sleep health. The Sleep Health Index is a comprehensive evaluation, indexing the nation’s sleep health. Developed by NSF in combination with the talents of sleep experts and public opinion research experts, the Sleep Health Index measures sleep health on three key scales: sleep duration, sleep quality, and sleep disorders. The Index is fielded quarterly and has accumulated responses from over 12,000 American adults. 

America is making gains in their sleep health. In the fourth quarter of 2018, US adults scored a new Index high of 77 on its 0-100 scale, up from 76 in the previous three quarters. Both the sleep duration and sleep quality sub-indices also reached highs of 79 and 70, respectively, indicating that people are reporting getting more and better sleep overall. Additionally, fewer people are having trouble staying asleep and more people are feeling well-rested. While scores vary between age, race, and socio-economic groups, as expected, the trends in the index reveal general improvements in knowledge of sleep and its associations with better health and wellness. NSF anticipates continued upward trends in scores as Americans learn more about the importance of good sleep health.
