One of the tools in our 'tool box' is awareness of the relaxation response, the opposite of the 'flight or fight response', drawing on a book by Herbert Benson M.D.
Learners with maths anxiety, and even some people we have met who suffer from severe general anxiety, ask 'why didnt anyone tell me about this before?'.
If a learner is feeling stressed or anxious, and/or is experiencing 'fight or flight', the learner can trigger the relaxation response in a short breathing exercise we teach called 5/7 breathing.
