Stress can occur at both, emotional, mentally, and physical level. 

Now that more is known about the dangerous effects of stress, there are more instruments available on the market to measure this.

The most important are:

• self reports (questionnaires or interviews)
• biochemical (analysis of stress hormones)
• monitoring behaviour (observation)
• physiological (analysis of the autonomus nervous system)

Self-reports, interviews and behavioural observation give definite indications but the standard can be highly subjective. Biochemical measures are suitably accurate but are not accessible to consumers who don’t have professional contact with the medical sector. 

Physiological self-analysis of your own nervous system is meanwhile more affordable. A number of bidders have developed products in this area. The majority of these products however still require professional supervision.  

Ease of use has been a central focus in developing the StressChecker and the BreathCoach, whilst at the same time not making any concessions  to the quality of measurement.  It is through this simplicity that it is possible to use the equipment without the need for professional supervision.More serious physical or psychological complaints should certainly be referred for specialist help. The responsibility for this lies fully with the user.
