We All Know Biking Makes Us Healthier. But It’s Even Better Than We Thought
   Research has consistently shown that people who are less physically active are both more likely to develop health problems such as heart disease and type 2 diabetes, and to die younger. Yet there is increasing evidence that physical activity levels are on the decline.  The problem is that when we have demands on our time, many people find prioritizing exercise difficult. One answer is to multitask by cycling or walking to work. We’ve just completed the largest ever study into how this affects your health.  Published in the British Medical Journal, the results for cycling in particular have important implications. They suggest that councils and governments need to make it a top priority to encourage as many commuters to get on their bikes as possible.  The findings  Cycling or walking to work, sometimes referred to as active commuting, is not very common in the UK. Only 3 percent of commuters cycle to work and 11 percent walk, one of the lowest rates in Europe. At the other end of the scale, 43 percent of the Dutch and 30 percent of Danes cycle daily.  To get a better understanding of what the UK could be missing, we looked at 263,450 people with an average age of 53 who were either in paid employment or self-employed, and didn’t always work at home.

Cycling to work was associated with a 41 percent lower risk of dying overall.  We followed people for around five years, counting the incidences of heart disease, cancers and death.
