Enhancement of Sleep With Wearables (WESA)

2 de março de 2021 atualizado por: Swiss Federal Institute of Technology

Enhancement of Sleep Slow Wave Activity Using Wearable Auditory Stimulation Devices and Its Consequences on Daytime Functioning: a Randomized, Counter-balanced Crossover Study

Sleep, specifically deep sleep, plays a central role in healthy brain function, cardio-vascular processes, mood and quality of life. Auditory stimulation during one night of sleep has previously been shown to improve deep sleep and along with memory formation in both young and older adults. Yet, it remains unclear whether long-term auditory stimulation considerably improves sleep quality over longer time periods and how it affects daytime functioning such as cognition, mood, quality of life and peripheral functions (e.g. cardio-vascular). Due to the importance of deep sleep for brain and body and the presence of many conditions that involve reduced deep sleep (e.g. ageing) assessing the beneficial impact of long-term sleep enhancement and its consequences is of central interest.This study will assess the effect of auditory stimulation over two weeks (interleaved with a two weeks washout period) in a cohort of healthy young and older adults using portable recording and stimulation devices.

Armas e Intervenções

Grupo de Participantes / Braço
Intervenção / Tratamento
Comparador Ativo: Application of tones
During non-rapid eye movement (NREM) sleep short tones will be played
During NREM sleep, tones (max. 60 dB) will be played using a portable, safe, in-home device. This device records biosignals (e.g. brain activity) and precisely times the tones during NREM sleep. It was developed and produced by the ETH Zurich and approved for use in this study by Swissmedic
Comparador Falso: No application of tones
During NREM sleep no short tones will be played
This is the sham-control intervention; The device will only record biosignals but will not play tones.

O que o estudo está medindo?

Medidas de resultados primários

Medida de resultado
Descrição da medida
Prazo
Sleep quality
Prazo: From baseline period to study completion, assessed up to 2 months
Objective information about sleep macro- and microstructure will be assessed including measures like sleep architecture, amount of slow wave activity (SWA), amount of spindles, awakenings during sleep, and sleep fragmentation. In addition, subjective sleep quality will be obtained by questionnaires every morning over the intervention period. These measures will show whether auditory stimulation enhanced overall sleep quality compared to sham.
From baseline period to study completion, assessed up to 2 months
