HSP will be structured in three levels. HSP1 is represented by this webpage and consists of the chronotype questionnaire.
In HSP2, participants will have the possibility to keep continuous sleep logs, which you can see as graphical representations and for which we will give you some analytical feedback. It you are interested in HSP’s sleep log system, please register here: [LINK].
HSP3 is still under construction. It will offer you the possibility to upload long-term activity recordings to our secure server. Similar to the other levels of HSP, HSP3 will offer detailed analyses of your activity and sleep patterns and will provide you with useful feedback.
