Answer

Increased muscular activity may involve any of the following:

  • Exercise

  • Convulsions

  • Strychnine poisoning

  • Sympathomimetics

  • Drug withdrawal

  • Thyroid storm

Moderate physical exercise, convulsions, and shivering can double heat production and result in temperature elevations that generally are self-limited and resolve with discontinuation of the activity.

Strenuous exercise and status epilepticus can increase heat production 10-fold and, when uninterrupted, can overwhelm the body's heat-dissipating mechanisms, leading to dangerous rises in body temperature.
