Tune into your inner rhythm

What is rhythmo.me?

rhythmo.me is a web application designed to help users get involved in the TEMPO study, run by the Rhythms in Physiology Lab (RiPL). This study investigates multiday cycles in resting heart rate, and their potential influence on how the body functions.
If you wear a smartwatch, we encourage you to participate. In doing so, you can:

• Learn about your heart rate's rhythms
• Find out what animal represents your heart chronotype
• Contribute to innovative research that could revolutionise our understanding of human rhythms and physiology

What is the TEMPO study?

Tracking the Effects of Multiday Physiological Oscillations

The aim of the TEMPO study is to understand the causes of multiday (weekly, monthly, and longer) cycles of physiological activity. Our research has shown that, like our regular body clock, which is generally a 24-hour (circadian) rhythm, there are also longer, multiday rhythms that may affect various biological functions, like resting heart rate, body temperature and more. This study will analyse multiday resting heart rate cycles from smartwatch data and track what effects your heart chronotype may have on your sleep, physical activity, regular function, mood and performance (such as memory and reaction time).

RiPL's research suggests that everybody has a different set of heart rate cycles, although one main cycle length has the most influence on your resting heart rate. These main cycles cluster into groups in the population, which we refer to as people's multiday chronotype.

In a small cohort study,

• Over 80% of adults had a multiday resting heart rate cycle.
• Around 50% of adults had a weekly cycle.
• Around 30% of adults had a monthly cycle.

Learning more about multiday cycles can lead to a better understanding of human physiology and may eventually improve the way we treat episodic and chronic conditions (such as epilepsy, migraines, cardiovascular disease) by using physiological cycles to manage disease symptoms.

To find your multiday chronotype, you will need to upload your smartwatch data.
