Dear vessels,

When you're battling the flu, it is best to avoid doing too much physical activity that is taxing to your body. When you're healthy, doing regular exercise is critical to diabetes management, but doing it when you're sick (or getting sick) can often bring it on sooner or make you even sicker.

If you feel good enough to do some light or moderate walking, that should be okay to do under those circumstances. Put your harder exercise off for when you're past the worst of your flu symptoms, though. Hard exercise temporarily suppresses your immune system, so working out too excessively while you're still sick can actually make you sicker or slow your recovery.
