Our bodies experience changes throughout the day, week, month, or year. Many of these changes are cyclic, meaning they repeat regularly over time. For example, typically our body experiences dramatic changes in breathing rate, temperature, and heart rate every night when we fall asleep. These changes occur as part of our circadian rhythm, but there are other more subtle rhythms that are of importance to our health and wellbeing, some occur multiple times a day (known as ultradian rhythms) and other over weeks or months (infradian rhythms). 

In this study, we wish to develop new ways of measuring these rhythms using wearable devices, that involve the least possible intrusion into the lives of those involved in the study. Furthermore, we wish to investigate how our sleep and wellbeing impacts these rhythms, and what causes them to become disrupted. In the future, we may use these findings in healthy populations to look for disruptions to biological rhythms in disease conditions.  

In this study we wish to:

• Measure biological rhythms (e.g. circadian rhythms) using different wearable sensors over four weeks.

• Validate measures from each of the sensors against others.

• Explore the relationships between each measurement (e.g. are rhythms in heart rate related to rhythms in movement, or sleep patterns?)
