Study 1: Relationship between sleep and mood

We are conducting research to see how sleep and emotions are related. All the information collected will be strictly confidential. We are looking for healthy volunteers who are students at the University of Oxford and aged between 18 and 25 years. Our study is non- invasive (no blood sampling) and ethically approved. You are free to withdraw from the study at any time and you will be rewarded for your time and effort.
