Sleep Science Friday: Keep the rhythm of your inner clock 

Sleep Science Friday  It’s the end of another week—grab a coffee/tea/beer/wine and end your week with a quick recap of Sleep Science News and ESRS updates!  Keep the rhythm of your inner clock  30 October 2020  After reverting to Standard Time last weekend, days are shorter as the sun sets earlier. And while the usefulness of time changes is debated—what do time shifts actually mean for your health? Although only an hour difference, some scientists suggest that these biannual time changes may be disruptive to our biological rhythms and sleep cycles. Recently, the American Academy of Sleep Medicine recommended in the Journal of Clinical Sleep Medicine that “the acute transition from standard to daylight saving time incurs significant public health and safety risks…and these seasonal …

What time is it? 23 October 2020 It’s that time of year again—the end of Daylight Saving Time (DST)—get ready to fall back this Sunday 25 October (2 AM) as we transition back into Standard Time. While morning larks may rejoice in brighter mornings, night owls encounter less natural light as evenings grow longer and darker.

This idea gained momentum—spreading across major industrialized countries …

Sleep Science Friday: Sleep-disordered breathing

Sleep Science Friday (3 Sept 2020) Happy Friday everyone! Grab a coffee/tea/drink to end your week with a quick recap of Sleep Science News following last Friday’s ESRS updates. As we learn more about COVID-19, certain underlying health conditions are shown to be associated with increased susceptibility and worse outcomes. Specifically, respiratory disorders, including sleep-disordered breathing (on the susceptibility side of COVID-19), along with a long road to recovery requiring lung rehabilitation in some patients (on the convalescence side). Sleep-disordered breathing Sleep-disordered breathing (such as obstructive sleep apnea) are characterized by intermittent hypoxia (low levels of oxygen) during sleep, sleep fragmentation, and hypercapnia (abnormally elevated blood CO2), which can activate multiple inflammatory pathways, alter lipid metabolism, and increase oxidative stress. …

Grab a coffee/tea/beer/wine and end your week with a quick recap of Sleep Science News and ESRS updates! “Ich habe mich verloren.” – Auguste Deter (16 May 1850 – 8 April 1906) Exhibiting paranoid and erratic behavior, delusions, and issues with speech and memory, 51-year-old Auguste Deter was examined by German neurologist, Dr. Alois Alzheimer, at the Frankfurt Institution of the Mentally Ill and Epileptics (Germany). Given her young age, Dr. Alzheimer initially labelled her condition as “presenile dementia”. Over the next several years, living in a state of confusion that progressively deteriorated, she soon lost sense of time and space—unable to recall her husband, where she was, and her own name—frequently uttering, “I …

Sleep Science Friday Yes! It’s Friday! Grab a coffee (or tea) and end your week with a quick recap of Sleep Science News and ESRS updates! COVID-19 and sleep (31 July 2020) The COVID-19 pandemic has upended our lives—with forced lockdowns, reduced travel, as well as job and financial insecurity during a worldwide economic recession. Although, many currently have reduced commuting time, more quality time with family, and the flexibility to work remotely (for some), learning to re-adjust schedules and coping with additional stressors (particularly as essential workers or those with children), has undoubtedly affected our sleeping quality and sleep patterns. Clea Simon (Harvard Correspondent), noted that “Sleep is emerging as the latest casualty of the COVID-19 crisis”, as people …
