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!
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. With first widespread introduction during WWI, DST was originally implemented to save energy by shifting clocks forward in the spring to add an additional hour of daylight in the evenings. This idea gained momentum—spreading across major industrialized countries (particularly during periods of “War Time”)—and eventually became a permanent fixture across ~70 countries worldwide. But with changes in energy consumption and the switch to electrical energy (from coal), critics of DST suggest that any energy benefits are limited and that time switching is archaic. And although only an hour difference, some scientists suggest that these biannual time changes may be disruptive to our biological rhythms and sleep cycles—leading to unintended consequences on health, social jetlag, and increasing rates of accidents.
These potential consequences and effects on certain industries has sparked an intense debate across the scientific, political, and public spheres regarding the future of DST over the last decade. In 2018, the EU Commission discussed abandoning time changes, with decisions on implementation delayed until 2021 due to the COVID-19 pandemic and as member states decide between preferences for DST or Standard Time. In the meantime, enjoy the extra hour of sleep this weekend and be mindful of your sleep cycles as we transition into winter.

Interested in or working on sleep and sleep-related research and medicine?
Attendees of the virtual edition of the 25th Congress of the ESRS (22 – 24 September 2020) still have access to all our amazing talks and posters online—extended until the 30 November 2020! For those who were unable to attend, stay tuned as we work on making the Congress more widely available on our ESRS website.
For more sleep talks—Sleep and Breathing (Virtual Edition) will be held on 15 – 17 April 2021. Organized by the ESRS and the European Respiratory Society, #SleepBreathe21 will be the largest pan-European meeting of its kind—offering an integrated approach in the investigation and treatment of sleep disorders with a focus on sleep respiratory medicine and science. See the scientific programme available online and submit your abstract by Friday 30 October 2021.
Have a great weekend (+1 hour)!
