Even if "downward-facing dog" doesn't sound particularly relaxing, a recent
study by Ohio State University found that women who routinely practised yoga
had lower amounts of the cytokine interleukin-6 (IL-6) in their blood, a stress
marker associated with ageing.
Yoga is also believed to improve circulation, boost serotonin (a
neurotransmitter that at low levels can adversely affect your mood), and
enhance flexibility. So it's worth considering a morning yoga class or even
at-home session - there are plenty of yoga DVDs and online classes available
for you to do in the privacy of your bedroom or living room.
