In large parts of the world, death rates are higher in cool and cold weather.

According to Rau (2007), the death peaks in the winter are linked to three main causes of death which are cardiovascular, cerebrovascular, and respiratory diseases. The latter group has the strongest seasonal pattern among all major groups of causes of death (Rau 2007). Cold temperatures have a physiological impact on the human body, and cold temperatures combined with low relative humidity rates are ideal for influenza virus transmission (Lowen et al. 2007). Furthermore, winter brings about behavioural changes that exacerbate respiratory ailments. People are more likely to congregate in heated houses, which increases the risk of droplet transmission of infectious agents (Evans 1991; Glezen and Couch 1997).
