Dr. Christian Benedict (Senior Lecturer & Associate Professor at the Department of Pharmaceutical Biosciences, Research and Pharmacology at Uppsala University, Sweden) talks about how to study sleep and its relevance for our overall health. In this first part, Christian introduces us to different definitions of sleep. Together, we try to decipher the concept of sleep quality or in other words how to judge if somebody had a good night’s sleep or not. Christian also summarizes the research around the optimal duration of sleep and discusses the relevanceof spending time in different sleep stages.

Studies that Christian refers to:

Aversive tobacco smoke during non-REM sleep

https://pubmed.ncbi.nlm.nih.gov/25392505/

Epileptic patients and sleep deprivation

https://pubmed.ncbi.nlm.nih.gov/29106402/

Correlations between time in different sleep stages and daytime alertness are not that good, contradictory evidence

https://pubmed.ncbi.nlm.nih.gov/10678518/

Epworthsleepiness scale and sleep stages are not well correlated

https://pubmed.ncbi.nlm.nih.gov/19110886/

People struggling with sleep do not necessarily differ in PSG-derived sleep stage outcomes from normally sleeping people

https://pubmed.ncbi.nlm.nih.gov/29402512/

Peer feedback can impact your retrospective judgement of your last night of sleep

American Society for Sleep Medicine, 7-9 hours, probably 6 and 10 hours are also fine

Shorter or longer than these 6-10 hours is mostly associated with poor health outcomes

Christian’s work on interindividual responses in brain health outcomes to sleep loss

https://pubmed.ncbi.nlm.nih.gov/36088460/

Studies showing that people who think they cope well with sleep loss are actually not doing well
