Light therapy and the beat of your blood: RAZOR full episode

In this episode of RAZOR, we get to grips with the power of light in treating neurological conditions and a novel way of monitoring blood pressure from beat to beat.

Javid Abdelmoneim is in Copenhagen, Denmark, where scientists are exploring how circadian rhythms and exposure to light may be able to treat neurological conditions in hospitals and care homes.

Ediz Tiyansan is in California, where UC Irvine scientists have taken the famous children's toys known as "shrinky dinks" and used that concept to develop wearable blood pressure sensors, which could revolutionize health monitoring.
