New research has shown that regular exercise boosts activity in the ammune system and helps reduce viral attack.

The study, published this week in the Journal of Infectious Diseases, suggests that exercise can reduce the severity of flu systoms and also clear out the virus more quickly.

In addition, exercising just before a flu infection but not regularly over the preceding months can also show some protection against severe symptoms.

The study suggests that exercise boosts “early innate antiviral defenses.” While the exact mechanisms remain unclear the results offer one more reason to engage in regular moderate exercise.
