How did you sleep last night?



No matter how you answer this question, you may rest easier knowing that you are not alone. 



Sleep issues can affect people of all ages and impact many parts of our lives.



While the science and nature of sleep is too complex to sum up on a single page, taking a peek at sleep statistics nationwide can help you understand key aspects of sleep health, as well as how widespread sleep issues are.



Our Sleep Cycles



Understanding the science of sleep 



In a normal sleep period, a person experiences four to six sleep cycles Trusted SourceNational Center for Biotechnology InformationThe National Center for Biotechnology Information advances science and health by providing access to biomedical and genomic information.View Source . 




  • While cycles vary in length, each sleep cycle can last about 90 minutes. 

  • Rapid eye movement (REM) sleep makes up 20% to 25% of total sleep in healthy adults.

  • As you cycle through non-rapid eye movement (NREM) sleep, various bodily functions slow down or stop altogether. Metabolism drops by around 15% Trusted SourceNational Library of Medicine, Biotech InformationThe National Center for Biotechnology Information advances science and health by providing access to biomedical and genomic information.View Source and both heart rate and blood pressure go down. 

  • Stage 3 NREM sleep or “deep sleep” is believed to be the most critical stage of sleep  for regenerating your body and brain. Deep sleep decreases across the lifespan, with one receiving less deep sleep as they age. 

  • On average, we spend about two hours per night dreaming Trusted SourceNational Institute of Neurological Disorders and Stroke (NINDS)NINDS aims to seek fundamental knowledge about the brain and nervous system and to use that knowledge to reduce the burden of neurological disease.View Source , mostly during REM sleep.

  • On average, adults sleep on their side 54% of the time Trusted SourceNature and Science of SleepView Source , on their back 38% of the time, and on their stomach 7%.



The sleep cycle goes through stages of light sleep, deep sleep, and active REM sleep.



The sleep cycle repeats several times throughout a single sleep period. During each cycle, time spent in each stage of sleep shifts.
