Practise regularly and check transfer
An eight-week study of 80 Chinese students compared language classes with and without emotion-regulation training. The training group showed better results for speaking anxiety, engagement and oral performance.
For sales practice: Build mental preparation into repeated role plays, then check how it transfers to real conversations.
Evidence and limitations: Four existing classes were compared, so class and teacher effects remain possible. This does not validate an individual reset drill or better prospecting results.
Assess box breathing with care
A systematic review reports possible short-term benefits for stress and mood. Physiological results are mixed, with substantial differences in protocols, participants and measurements.
For sales practice: Try calm preparation as a personal routine and observe its usefulness in daily work. Avoid presenting any breathing technique as a performance guarantee.
Evidence and limitations: Long-term evidence is limited and B2B conversation performance was not tested. The published abstract contains inconsistent study counts, so no total is reproduced here.
