This presentation examines the broad theme of human needs with specific reference to a range of winter-induced problems. Both physiological and psychological aspects are analyzed vis-dt.vis thermal comfort and human behavioural response. The use of public space suggests that social activity is very different in winter when compared with summer. However, such activity can be increased through employing planning and design strategies. For example, the outdoor season can be extended by up to six weeks by applying microclimatic principles. If more intense levels of social interaction are desired --when people tend to be confined indoors --proximity and density will be important factors influencing such contact, thereby contributing to a reduction of stress and isolation. Since winter conditions spawn unique problems, special solutions will be required to combat them. It is essential to create a better 'fit' between human requirements and the corresponding built environment.
Any set of statistics will show that these diseases have a very pronounced seasonal course. Usually, there is a peak of deaths in mid.winter, in January and February. In summer many fewer deaths occur.
