So it’s supposedly summer time and a time when many of us fly off on our summer holidays with the children, friends and partners. Lengthy travel by any means aggravates ‘vata’, the principle of movement. Air travel in particular, can drive our vata soaring, as you travel at high speed travel in vata’s own elements of space and air. The dry, re-circulated air, increased cabin pressure and high altitude add extra disruption to the already disturbed diet and lifestlyle routines and time zone changes.
