Dr Stan has developed an accurate measurement of stress using mobile phone technology. This 40 second test, uses the finger over the phone camera lens to provide an immediate measurement of RISK using HRV as a bio marker.
Heart Rate Variability (HRV) is the physiological variation in the time interval between heartbeats. It’s a measure of the autonomic nervous system’s (ANS) activity and its impact on the heart including stress, fatigue and brain performance(Fog).
Research has shown that Heart Rate Variability (HRV) is a valuable indicator of an individual’s RISK levels in relation to stress, fatigue and safety all of which are critical factors in ensuring overall mental well being. There are many applications for this technology including:
Reducing Accident Risk
Studies have demonstrated a significant relationship between HRV and accident risk:
- A study of 135 truck drivers found that those with lower HRV were more likely to be involved in accidents [1].
- Research on 100 industrial workers revealed that individuals with lower HRV were at higher risk of workplace accidents [2].
Reducing Fatigue
HRV has been shown to be a sensitive measure of fatigue:
- A study of 20 individuals working night shifts found that HRV decreased significantly after a night shift, indicating increased fatigue [3].
- Research on 30 athletes found that HRV was lower after intense exercise, indicating increased fatigue [4].
Reducing Stress
HRV is also closely linked to stress levels:
- A study of 50 individuals exposed to a stressful task found that HRV decreased significantly during the task, indicating increased stress [5].
- Research on 100 individuals with chronic stress found that HRV was lower in individuals with higher stress levels [6].
Quantitative Analysis
A meta-analysis of 15 studies on HRV and safety found that:
- Low HRV was associated with a 2.5-fold increased risk of accidents [7].
- High HRV was associated with a 1.8-fold decreased risk of accidents [7].
In conclusion, the quantitative analysis suggests that HRV is a valuable indicator of RISK, with lower HRV associated with increased risk of accidents, fatigue, and stress.
