How can the integration of wearables and smart devices in preventative healthcare potentially shift the focus from reactive treatment to proactive wellness management, and what implications could this have on the healthcare industry as a whole?

The integration of wearables and smart devices in preventative healthcare can shift the focus from reactive treatment to proactive wellness management by providing real-time data on individuals' health metrics. This allows for early detection of potential health issues and enables individuals to make informed decisions about their health. This shift towards proactive wellness management could lead to a decrease in healthcare costs, as prevention is often more cost-effective than treating advanced diseases. Additionally, the healthcare industry may need to adapt to incorporate more preventative care services and data analytics to effectively utilize the information collected from wearables and smart devices.
