Dear members of the ESRS/readers of JSR, Welcome to the sixth edition of the Journal of Sleep Research in 2025, which will be published in December. Many of you will know already that my tenureship as Editor-in-Chief (EIC) of the Journal of Sleep Research will expire at the end of this year 2025—hence the title. Please allow me a few words about the last 9 years from 2017 to 2025.
