[Hormone changes during the sirocco]

The results of a study of 15 subjects on the occasion of a sirocco wind are reported. Behaviour of ARP, aldosteronaemia, cortisolaemia, Ht and serum electrolytes was assessed. A significant increase in ARP, aldosteronaemia and Ht was observed during the sirocco, while serum electrolytes went down. Cortisolaemia did not perform uniformly, increasing in some subjects and falling in others.
