The purpose of this research is to gain an understanding of how activity and sleep relate to mood in a
sample of individuals over a four-week period. We are looking for healthy volunteers, aged 25-45, to
complete a 4-week study from the comfort of their own home/workplace. To be eligible for this study
you must be:

  1. an “office worker” (you work sitting at a desk, indoors, for your working day)
  2. living within the Oxford Ring Road, full-time (Monday-Sunday), in August/September 2021
  3. working within the Oxford Ring Road, full-time (“9-5”, Monday-Friday), in August/September 2021
  4. a smartphone user with a consistent internet connection indoors and outdoors
  5. able to read and understand English

You would complete the study whilst going about your daily life. You would wear a watch-like device
for 4-weeks and you would complete three 1-min daily surveys. At the start, middle, and end of the 4-
weeks, there will also be 3 additional short surveys to complete.

If you wish to participate, please follow this link which will take you to our screening survey: If you complete the screening survey, you will be entered into a lottery
