Shouting it out does not empty the tank. Going over it loudly, in your head or at somebody, tends to keep the anger topped up rather than draining it.

What the research says

In a set of experimental and cross sectional studies, people who exercised regularly recovered from a laboratory stressor with less rumination, and a single bout of exercise improved recovery. A laboratory stressor is not a family row, and part of the evidence is cross sectional, so the causal claim should stay modest. It points towards moving the body rather than replaying the incident.

Strength of evidence: one line of research. A single study, or a theoretical account.
