Stress monitoring for individuals in moving structures

A method for monitoring stress of an individual in a moving structure by estimating and monitoring a mental component of a total heart rate of the individual,

• whereby the total heart rate (HRTotal) comprises a mechanical component (HRMechanical) and the mental component (HRMental), and
• the total heart rate (HRTotal) further comprises a component relating to heat balance (HRHeat Bal) and a component relating to basic metabolic functions (HRBasic Met),
• wherein the method comprises the steps of
• measuring a movement of the individual in real-time,
• measuring a movement of the moving structure in real-time,
• estimating the mechanical component (HRMechanical) in real-time based on the real-time movement of the individual and the real-time movement of the moving structure,
• measuring the total heart rate (HRTotal) in real-time,
• obtaining the mental component (HRMental) by subtracting the mechanical component (HRMechanical), the component relating to the heat balance (HRHeat Bal) and the component relating to basic metabolic functions (HRBasic Met) from the total heart rate (HRTotal), and
• outputting a level of stress corresponding to the mental component (HRMental).
