In the age of wearable health technology, what steps can individuals take to ensure that their personal health data is not being sold or shared with third parties without their consent?

Individuals can protect their personal health data by carefully reading and understanding the privacy policies of wearable health technology devices before using them. They should also regularly review and update their privacy settings to control how their data is shared. Using strong passwords and enabling two-factor authentication can also help prevent unauthorized access to their health data. Additionally, individuals can choose to only share necessary information with healthcare providers and carefully vet any third-party apps or services that have access to their data.
