Take a 'head down' approach. That's the advice of Artur Luczak, from the Canadian Centre for Behavioural Neuroscience, University of Lethbridge, who has written a paper on the subject.

The technique involves inverting the head and upper body by going into a "downward dog" position or by hanging upside down off the front of a chair.
