Skin temperature regulation is a complex system that depends on blood-flow rate, local structures of subcutaneous tissues and the activity of the sympathetic nervous system.Based on the Homeostasis principle, humans are supposed to be thermally balanced, that is to say, we should have similar temperature in the left and right region.

Thermal asymmetries on regions of interest (ROIs) could show a potential injury risk due to factors related to workload assimilation, biomechanics, tissue physiology and nerve dysfunction. According to our research and practical experience, we propose a thermal asymmetry classification scale, which will start from bilateral skin temperature differences above 0,3ºC.

Europa Thermohuman ThermoHuman has had the support of the Funds of the European Union and the Community of Madrid through the Operational Programme on Youth Employment. Likewise, ThermoHuman within the framework of the Export Initiation Program of ICEX NEXT, had the support of ICEX and the co-financing of the European Regional Development Fund (ERDF).

CDTI Thermohuman has received funding from the Centre for the Development of Industrial Technology (CDTI), in participation with the European Regional Development Fund (ERDF), for the R+D activities involved in creating a new tool, based on thermography, for the prediction and prevention of rheumatoid arthritis.
