Smart devices and healthy aging

Chronic diseases, such as cardiovascular disease, cancers, chronic respiratory diseases, diabetes mellitus, and neurodegenerative disorders represent major global health problems to society, and their incidence and prevalence continue to increase. Chronic diseases share common risk factors, including socio-economic factors and co-morbidities and, importantly, their risk increases with age. The silent transition from health to disease with a late onset of symptoms can delay treatment and interventions. Healthcare-systems must thus evolve proactive rather than purely reactive approaches to care once symptoms appear. Many self-tracking technologies (based on wireless biosensors) are readily available to the general public that monitor and record personal bio-related data. These biosensors may be wearable, implanted in the body or installed on a device. The aim of this review is to discuss the current market and proven utility of wrist-worn devices, in improving and maintaining a healthy lifestyle. Optimizing the technological opportunities for monitoring good health has the potential to empower people and help many enjoy a high quality of life.
