<div>Dear Friends </div>

<div>The GACC newsletter has an article that starts thus:</div>

working to improve public health in Nepal, where household air pollution accounts for over 18,000 deaths each year. </span></div>

</span></div>
<div>Household air pollution includes quite a lot of contributing factors. Are these deaths accompanied by a death certificate saying 'air pollution' as a cause? A contributing cause?</div>
<div><br>
</div>
<div>From what we have learned on this list it seems unlikely 18,000 people are killed each year by indoor air pollution in Nepal. I am not saying it could be true, it just seems really unlikely that this is a fact. </div>
<div><br>
</div>
<div>I have been reviewing the results of the health study that paralleled the Kyrgyzstan Stove Pilot this past winter. There are two sets of dramatic changes: the reduction in symptoms related to inhalation of smoke and CO, and this related to a higher indoor
temperature. </div>
<div><br>
</div>
<div>Looking through the list, the medical issues or hints of them related to temperature are very noticeable: runny nose and bronchitis are two that are related to chronic under-heating. What we see is that with a five degree higher indoor temperature these
symptoms of 'cold' pretty much disappear. </div>
<div><br>
</div>
<div>Nepal is largely very cold in winter. 'Deaths' premature or otherwise are surely far more commonly attributable to chronic under-heating, compared with IAQ, not so?</div>
<div><br>
</div>
<div>I think there is much to glean from the Fresh Air study in Kyrgyzstan as most confounding factors are not present. </div>
