The system further includes at least one photoplethysmography (PPG) sensor configured to continuously measure biometric data. A live messaging module is configured to send at least one notification message to one or more second users associated with the first user through a network when at least one event associated with the first user occurs. The at least one notification message informs the one or more second users about the at least one event so that at least one second user of the one or more second users takes an action to ensure safety of the first user. The system further includes a learning module in communication with the at least one PPG sensor. The learning module may use machine learning (ML) and artificial intelligence (Al) to determine health information based on the measured biometric data of the first user.1/5 C0 z0 00 z w 4 0 0 -(1 --- - : 0 I IU 00 w u o 0
