[Effects of heat waves on mortality in Germany].

Heat waves present an increasing threat to population's health; there is increased activity in terms of research and preventive measures since the heat waves in 2003. This is the first narrative review of studies on heat wave-associated mortality in Germany. The review and critical evaluation includes 12 studies. Notable differences in the research methodology were observed. Scientific knowledge on heat wave-associated mortality in Germany is insufficient. So far, most studies have focused on large cities or states/provinces. However, risk assessments play an important role in deciding upon and planning of preventive measures. © Georg Thieme Verlag KG Stuttgart · New York.
