Stave off January colds with moderate exercise
(Relaxnews) - If your New Year's resolutions involve running a marathon or some other strenuous goal, experts warn that overexerting yourself could increase your risk of catching a cold or flu this season. Your best bet: exercise in moderation. On the table at Friday's Association for Science Education (ASE) Conference, expert Mike Gleeson of Loughborough University in the UK adds that prolonged strenuous exercise, such as training for a marathon, can make you more susceptible to illness, especially upper-respiratory tract infections (URTI) -- including colds, tonsillitis, sinusitis, and flu.
