This section links to resources for exercise and for using light therapy. Exercise is an absolutely key component of what this website is primarily about - achieving improvements in our stress, health and wellbeing. Try, for example, clicking on this exercise tag to see a series of relevant blog posts. The gains from exercising more are so huge that they have major implications for government health budgets - unfit populations get sicker and cost much more to look after. It's no surprise then to find that there are many excellent, nationally developed, internet sites giving high quality exercise information.
