A new cluster headache precipitant: increased body heat.
Exercise, a hot bath, or elevated environmental temperature provoked cluster headaches, within 1 h, in 75 out of 200 patients. This new observation accords with recognised precipitants--alcohol, histamine, and gyceryl trinitrate--perhaps via generalised vasodilatation or hypothalamic activation.
