Caffeine and sleep

⭐ We are looking for research participants for 2026 🍵

You are invited to participate in our research study, which will help us find out more about how caffeine consumption affects sleep and vice versa.

Who can participate?

We are looking for people who are:

• Currently living in Aotearoa New Zealand
• Aged 18-64 years old
• Working at least 30 hours per week
• In good general health with no current medical condition and/or not taking medication that is likely to affect your sleep
• A non-smoker

What’s involved?

First, you will complete a set of online questionnaires (20-30 minutes in total) to check if you are eligible.  If you are selected, you will need to wear a sleep/wake activity monitor (actigraph) and complete a daily sleep diary for 14 days.  You'll start these activities in early 2026.
