What causes rigor? Rigors are triggered by
the presence of chemicals called pyrogens in the blood which ‘turn up' the body's thermostat setting, telling the body to aim for a higher target temperature
. Pyrogens are produced by our own immune systems in response to certain triggers, of which infection is the most common.
What causes rigor attacks?

Why do dead bodies get stiff?
The cells no longer have the energy to pump calcium out of the cell and so the calcium concentration rises, forcing the muscles to remain in a contracted state
. This state of muscle stiffening is known as rigor mortis and it remains until the muscle proteins start to decompose.
