Acute mackerel-induced sleep in a young researcher
Sleeping disorders are common and they are associated with substantial psychological and physical strain in those affected. We report a case of sudden onset of deep sleep in a 29-year-old Danish woman just after intake of mackerel in tomato sauce. There were no abnormal findings in the physical examination and no suspicion of underlying neurological disease. We hypothesize that the observed association between mackerel intake and deep sleep is causal and we suggest that more research is conducted in order to establish the potential of mackerel in treatment of sleeping disorders.
