The typical mistake
People try to breathe deeper and faster, which can increase tension. The key is smoothness and a longer exhale.
The 4-6 scheme
Inhale for 4 counts, exhale for 6. Repeat 5-6 cycles. The pace should be comfortable, without holds or excessive effort.
When to apply
Optimally 2-3 minutes before the event. This lowers physiological tension while keeping mental clarity.
