While the article speaks mainly of Russians the same is true in Kazakhstan. Multiple cups of tea a day are a norm here. I can understand that in the winter when it can help you warm up. However, many people in Kazakhstan have advised me drink a hot cup of tea even in the summer as way to cool down. Wait! I don't get it. The explanation is that drinking a hot cup of tea makes you sweat and thus cool off. I don't need anymore help sweating. But, I've been here for two years so I know that integration is important. I'll take that cup of tea...s l'dom.
Oh a side note, I'm leaving my site, Shymkent, today so I will be one of the lucky ones missing out on the 109 degrees.
Stay cool.
