I have tried many reminders including manual/digital timers, iWatch, standalone apps, etc. but this lightweight free "eyeCare" Chrome extension is the best of all that I've tried thus far with audible/visual notification with adjustable time. It's actually a reminder app to exercise your eyes to prevent macular degeneration that you can repurpose to take a break from what you're doing. If you know of something better, please let me know.

Why is moving so important for PD? The circulatory system has the heart to pump blood, but your lymphatic system has no pump; it is dependent on your movement and contraction of the muscles to allow the lymph fluid to flow. Among other functions, your body depends on the "sewerage system" to detox waste, bacteria/ viruses, toxins, metabolites, and abnormal cells that can lead to various illnesses. If this crucial detoxification drainage system is stagnant or insufficient, it can directly result in elevated oxidative stress among other comorbidities.
“Findings suggest that lymphatic clearance dysfunction is crucial in the onset and development of PD, and might be therapeutically targeted to alleviate age-associated neurodegenerative disorders.”
