> At work: Get hold of a footstool and put your feet up! Do ankle exercises every couple of hours (stand on tip-toe and then back onto your heels).
> At night: If you can, sleep with your feet raised higher than your heart (by 12 - 15cm). Raise your mattress with a bolster, or try raising the foot of your bed.
> When you're travelling, make sure you stop every couple of hours to have a stretch and a walk around. If you're on a train, go for regular walks, and if you're travelling by plane make sure you wear in-flight compression socks and ask for an aisle seat so that you can move about easily.
> Try and get about on foot as much as possible.
> Take regular lukewarm or cold baths with a big handful of rock salt thrown in.
