Flu risk 'cut by vigorous exercise'

Runners  

Running is one form of potentially "flu-beating" exercise 

Doing at least two and a half hours of vigorous exercise each week cuts the chance of developing flu, new data suggests.

Around 4,800 people took part in this year's online Flu Survey, run by the London School of Hygiene and Tropical Medicine.

Moderate exercise did not appear to have a protective effect, the researchers said.

Overall, flu rates have been relatively low this winter.

The Flu Survey, now in its fifth year, tries to track as much detail as possible about who does and does not get flu.

One of the questions people must answer when they register, as well as their age, if they are around children and if they have been vaccinated, is how many hours of "vigorous exercise" they do each week, such as running, fast cycling or competitive sports, ranging from none to more than five hours.

They are then asked to log in each week and note how they are feeling, and whether or not they have any flu-like symptoms.
