God #hälsa ombord beror i mycket stor utsträckning på bra #sömn - är min uppfattning i alla fall som ni kan läsa mer om i tidskriften #Sjömannen #3 2025. Tack Hanna Welin för intervjun!

This study demonstrates that applying rhythmic #sensory stimulation during a whole night of #sleep boosts sleep maintenance (i.e., decreases in sleep fragmentation and light sleep duration), with an associated increase in sleep efficiency. www.biorxiv.org/content/10.1...
Whole-night gentle rocking improves sleep in poor sleepers with insomnia complaints
Specific brain oscillations can be manipulated during sleep to improve sleep quality and memory performance. We previously demonstrated that continuous rocking stimulation (0.25Hz, lateral movement) a...

This study supports a modernized ‘screen-sleep-displacement theory’. It empirically demonstrates that screen-sleep displacements impact several aspects of #sleep simultaneously.

Adolescents’ screen time displaces multiple sleep pathways and elevates depressive symptoms over twelve months
Recently the Swedish Public Health Agency published recommendations of a maximum of two-to-three hours of daily leisure screen time for adolescents aged 13–18, partly to promote better sleep (2024-Sep...

😴 Cavemen did more things right than you might think. After all, they discovered fire and invented the wheel, points out Merijn van de Laar, author of a new book, How to Sleep Like A Caveman.
And one of the best things they can teach us about is sleep.

Timing patterns of brainwaves created by a sleeping brain, known as sleep spindles, are so individually distinct that they could function like fingerprints. The framework could pave the way for the development of sleep biomarkers. In PNAS: www.pnas.org/doi/full/10....
