The SmartSleep Experiment

The SmartSleep Experiment is part of the greater SmartSleep research project, which aims to map the behavior of the Danish population, in relation to the use of smartphones at night

The first step in this is a questionnaire that we invite all Danes from the age of 16 and up to participate in.

To spread the knowledge about the project and the questionnaire we gained the help of The Danish Broadcasting Corporation and the radio show ‘Go’ morgen P3’ who, from the 12th through to the 16th of November 2018, had a big theme about sleep.

It is our hope, that as many people as possible will participate in answering the questionnaire, so we can collect as much data as possible.

If you want to participate (in Danish only) you can do so below. It only takes 10 minutes and you will get a personal feedback at the end.

Participate in the SmartSleep Experiment

The SmartSleep project is also a Citizen Science project. Citizen Science means that scientists need the knowledge, help, and experience that the public carries around. These experiences can then benefit us all through a better understanding of our mobile- and sleep habits.

Why is this experiment important?

Firstly, most of the research on the area of sleep and smartphones focus on the period just before you fall asleep. We know very little about how we use mobile phones at night. SmartSleep hopes to change this.

Secondly, our use of digital devices at night might have a great influence on our physical and mental health. It is our hope that we, through the research project, can see these correlations more clearly and thereby help prevent negative effects.

Thirdly, a citizen science project like this helps strengthen the dialogue between scientists and citizens, and also helps us harness and use the knowledge and resources that exist, to the benefit of us all.

The preliminary results from the questionnaire answers will be published on this site from the 28th of November.

SmartSleep Research

Sleep is an important biological process that allows our body to recover and regenerate. This is important to our health and crucial to how we function in daily life.

Today, nearly all of us have mobile phones that we take with us everywhere we go – also to bed.

The purpose of the SmartSleep project is to investigate how our mobile phones affect and disturb our nightly sleep. Besides this focus, we also wish to examine how our health is affected by mobile use at night, in the long run.

Most of the existing research on the area of sleep and smartphones focus on the period just before you fall asleep, but SmartSleep wishes to know mobile phone habits of the Danish population after we fall asleep - or are supposed to be sleeping.

Besides the SmartSleep Experiment, data from a group of young adult volunteers, are to be gathered. The participant’s mobile habits are monitored and at the same time, they will be subjected to clinical health studies. The hope is that these Data will help create an even more nuanced picture of Danish mobile phone use and the possible health consequences.

The entire project will span three years and hopefully increase our knowledge of how our mobile habits affect our health and how well we really sleep at night.

The SmartSleep project is financed with funding from the Independent Research Fund Denmark
