BIG Sleep Study

People respond very differently in response to a lack of sleep. The aim of this study is to investigate which factors determine why people are so differently affected by a lack of sleep.

You can participate if you are:
-Between 18-50 years old
-Fluent in English or Swedish
-Unaffected by sleep disorders or a severe mental health disorder
-Can abstain from coffee and smoking/snus for 1 day without problems

You will be invited to come to our lab on three separate occasions. During the first session, you will fill out questionnaires and learn more about the study measures (3h).

After the first session, you will be invited to the lab for 2 more sessions (3h30 each) during which you will perform several tasks, complete questionnaires, and a blood sample will be taken. Before coming to the lab for these sessions you will need to have slept 4 hours per night for two consecutive nights for one session and 9 hours per night for two consecutive nights for the other. All sessions will have to be separated by a minimum of 7 days. The sleep protocol will be performed AT HOME.

The study takes place in your own home and at Stress Research Institute of Stockholm University (Albano).
Compensation: 1200 SEK (taxable) plus you can win an additional 130 SEK (taxable) based on how well you perform on some of the tests.
