1. A system for monitoring fatigue and notifying a user, the system comprising:

  • a wearable apparatus comprising;

    a sensor configured to measure biomarkers of the user;

    a communication module; and

    a support configured to support the sensor; and

    a remote device comprising;

    memory;

    a notification generator configured to generate a warning to the user via the communication module in response to receipt of a signal;

    a processor communicatively coupled to the sensor and the notification generator, the processor configured to;

    obtain, from the communication module, biomarker measurements from the sensor;

    generate a personal circadian rhythm for the user, and a position of the user along that circadian rhythm, using the measured biomarkers;

    identify a baseline risk level for the user by assessing the personal circadian rhythm of the user and the position of the user along that personal circadian rhythm;

    determine a sleep drive of the user based upon continual or periodic sensor measurements, wherein sleep and wakefulness cycles of the user are derived from actigraphy data obtained from the sensor; and

    send the signal to the notification generator when the baseline risk level is in a predetermined range.
