Abstract: A method according to one embodiment includes determining whether a user has successfully heat acclimatized to a predetermined environment. Subsequent to a determination that the user has successfully heat acclimatized, it is determined whether the user has heat de-acclimatized to the predetermined environment. In response to a determination that the user has heat de-acclimatized, a predetermined process is performed. The predetermined process includes determining whether the user has successfully heat re-acclimatized to the predetermined environment.

Abstract: A method according to one embodiment includes receiving baseline health data of a user, receiving activity-based health data of a user collected by a sensor device worn by the user while participating in physical activity and receiving environmental-based data of the user. A personalized heat risk level alert is generated and includes a personalized heat risk level stratification of the user. The personalized heat risk level alert is output for display on a user device. The method further includes generating a guided activity plan for the user to participate in for a predetermined amount of time while wearing the sensor device, and outputting the guided activity plan for display on the user device. Second activity-based health data of the user collected by the sensor device worn by the user while participating in the guided activity plan is received and a heat tolerance alert is generated.

Abstract: A method according to one embodiment includes receiving baseline health data of a user, receiving activity-based health data of the user collected by a sensor device worn by the user while participating in physical activity, and receiving environmental-based data of the user. A baseline core body temperature of the user is calculated. It is determined whether a core body temperature of the user has increased a predetermined amount from the baseline core body temperature of the user for a predetermined amount of time during each of a predetermined number of time intervals. In response to a determination that the core body temperature has increased the predetermined amount from the baseline core body temperature of the user for the predetermined amount of time during each of the predetermined number of time intervals, a personalized schedule is generated for the user to follow while participating in the physical activity.

Abstract: A method according to one embodiment includes receiving baseline health data of a user, receiving activity-based health data of a user collected by a sensor device worn by the user while participating in physical activity, and receiving environmental-based data of the user collected by the sensor device worn by the user and/or from an external application programming interface (API). A personalized schedule is generated for the user to follow while participating in the physical activity based on the baseline health data of the user, the activity-based health data of the user and the environmental-based data of the user. The personalized schedule includes at least one instruction of an amount of fluids for the user to consume while participating in the physical activity to maintain hydration of the user and prevent dehydration of the user. The method further includes outputting the personalized schedule for display on the user device.

Abstract: A method according to one embodiment includes receiving baseline health data of a user, receiving activity-based health data of the user collected by a sensor device worn by the user while participating in physical activity and receiving environmental-based data of the user collected by the sensor device worn by the user. An alert is output for display on a user device in response to a determination that a core body temperature of the user is greater than a predetermined threshold temperature. A personalized schedule is generated for the user to follow while participating in the physical activity. The personalized schedule includes at least one instruction of when to start participating in the physical activity and at least one instruction of when to stop participating in the physical activity. The method further includes outputting the personalized schedule for display on the user device.
