About Detant

DETANT was established by military and civil security experts and veteran martial art practitioners. We learned from our vast experience in these fields that one have to control the power he possesses.

Emotional control in the midst of extreme situations can not be learned verbally. We know that in order to function in the best possible way at any given incident, a clear, calm and composed mind is a necessity.

The way to make this mind set available is via physical techniques, techniques done in the body that utilise parasympathetic activation when needed, deep emotional effects and system two thinking. Our workshop is a paradigm shift and is followed closely by our CSO and academical research.

Combining our diverse knowledge we developed simple physical procedures that can be applied easily in the field, in real time.

The procedures in our workshops give an exact set of tools. The cognitive, the emotional and the physical cross influence, but it is mainly through the physical – and that means done in body – practices that we can set a measured reaction, stay focused and maintain control in emotionally chaotic times.
