What to do in winter?
By Marie-Louise Bird
If you live a long way from the equator, the amount of daylight that you have access to in summer compared to winter varies hugely. For example at 41 degrees (Launceston in Tasmania, Australia, Boston MA, USA and Portugal, Europe) the length of daylight varies from just over 9 hours in winter to over 15 in summer and even more dramatic at 53 degrees, with hours of daylight from 7.5 in winter to 17 in summer. It is not surprising that this will have impact on the total amount of physical activity that people perform in the different seasons with less activity in winter (14% at 41 degrees south).
