The resting measures point in different directions. Diastolic pressure falls slightly, from 69.8 to 67.5 millimetres of mercury, and slow electrical activity in the brain rises by one to three hundredths at four of eight sites, the frontal ones and one temporal. Heart rate, on the other hand, does not change significantly (from 73.8 to 69.7 beats), and neither do systolic pressure or beta activity, at any of the eight sites. With half the indices moving and half standing still, no control group and eight comparisons made without correction, it cannot be said that the programme lowers arousal; and none of the measures concerns shooting.claim:rilassamento-attivazione-riposo:revision:2026-04-08:2Wed, 08 Apr 2026 08:00:00 GMT https://matteocampagna.com/en/registry/mind/progressive-relaxation-resting-arousalclaim:rilassamento-attivazione-riposo:new_claim:2026-02-23:contestatoMon, 23 Feb 2026 08:00:00 GMT
