Collective rituals are present in all known societies but their functions are matters of long-standing debates. This ambitious and technically demanding study produced the first *quantified* demonstration from a natural human ecology that an extreme collective ritual coordinates the arousal of participants and spectators. We found that during a Spanish firewalk, the heart rhythms of spectators became aligned to known firewalkers. Intriguingly, spectators who were related to at least one fire-walker exhibited shared patterns of arousal to unknown fire-walkers. This suggests that an extreme ritual may extend the boundary of empathetic concern from related to unrelated performers. Quantifying a ritual reveals unnoticed subtleties.

The article received global attention, for example:
