Although you won’t hear it tick, your body has its own internal clock regulating your circadian rhythm. Your circadian rhythm is your sleep-wake pattern over the course of a 24-hour day. Most living things have it, including animals, plants, and even some microbes.

Circadian rhythms affect your sleep patterns as well as other ways your body works, like your body temperature, eating habits, and hormones. When your internal clock gets out of sync, it might cause problems with your health. They’ve been linked to different disorders including diabetes, obesity, and depression. Maintaining healthy habits can help you respond better to this natural rhythm of your body.

In this final episode of BioSounds season 3, our correspondent Rouaa Ben Chaabene, interviews Prof. Emi Nagoshi from the faculty of Sciences where she talks about her work on circadian rhythms and how it can be linked to Parkinson’s disease.
