Abstract
Background: An earlier study showed that a week of yoga practice was useful in stress management after a
natural calamity. Due to heavy rain and a rift on the banks of the Kosi river, in the state of Bihar in north India,
there were floods with loss of life and property. A week of yoga practice was given to the survivors a month after
the event and the effect was assessed.
Methods: Twenty-two volunteers (group average age ± S.D, 31.5 ± 7.5 years; all of them were males) were
randomly assigned to two groups, yoga and a non-yoga wait-list control group. The yoga group practiced yoga for
an hour daily while the control group continued with their routine activities. Both groups’ heart rate variability,
breath rate, and four symptoms of emotional distress using visual analog scales, were assessed on the first and
eighth day of the program.
Results: There was a significant decrease in sadness in the yoga group (p < 0.05, paired t-test, post data compared
to pre) and an increase in anxiety in the control group (p < 0.05, paired t-test, post data compared to pre).
Conclusions: A week of yoga can reduce feelings of sadness and possibly prevent an increase in anxiety in flood
survivors a month after the calamity.

Background
In August 2008 due to preceding heavy monsoon rains
there was a breach in the embankments of the Kosi
River near the Indo-Nepal border [1]. The breach
caused loss of life and property in the north Indian state
of Bihar, affecting more than 2.5 million lives.
A month after the event most of the survivors were
still housed in temporary shelters as the waters had not
receded. As the population consisted mainly of farmers,
the possibility of them continuing their occupation
appeared uncertain with the possibility of land remaining
waterlogged or sand cast after the water receded.
At this stage, a month later, an attempt was made to
introduce yoga as a stress-reducing strategy. The ancient
Indian science of yoga includes the practice of specific
postures (asanas), cleansing practices (kriyas), voluntarily
regulated breathing
