Use any asana Kaga or Chintan the result is the same. Now it is height of linkages with Yoga and what not.  @Suni51 , where are you?

In villages and small towns our traditional way is still followed, but in metro cities our traditional toilets are replaced with western toilets and due to which most people are facing digestion problems.

I don't think so. It's not true that traditional toilets are entirely replaced with Western type toilets in Cities and Metros. Traditional toilets are also there in cities and Metros.Additionally, digestion problems are there even in traditional toilet users.

It all sums up to one thing. That is, Toilet users be it traditional or Western type see the convenience. I have seen many western type toilet users free from  digestion problems or to that matter any kind of health problems.

I fail to understand linkage between toilet posture and digestion. How can the last step affect the first step in a series  of reactive steps is not clear.

Ease of use, hygienic factors and less wastage of water. Nothing else. Western type of Toilets offer these advantages.

According to the link "It is common practice in the West to sit on a toilet in a similar fashion to how one sits on a chair, with back straightened and feet on the floor, and it may be this typical defecation posture that is causing such widespread digestive problems amongst the populace. The 90-degrees defecation posture, formed by the bending of the hips and knees at right-angles when sat upright on a pedestal toilet, can cause narrowing of the point at which the anus and rectum are joined which may complicate the passing of stools. The strain placed on the colon by defecating at a narrow anorectal angle can cause both long-term and short-term bowel problems."

The Western people have no problems otherwise they would have changed their posture long ago. Let persons chose their postures as per their comfort.

I agree with you. Western Type of toilets do not pose any health problems. While this discussion was in progress, a visitor came to me. He has an apartment in which both types of Toilets are there. According to their convenience , his wife and himself use  both type of toilets. Never they had any health problems.

I agree that people use toilets according to their comfort, but many claim that Indian traditional toilets are the best.

Very convincing explanation favoring Traditional Indian toilet. In Yogasanas,  a popular pose called Shashanasana is capable of massaging abdominal organs and stimulating the nervous action of the bowels. This leads to an effortless motion.

But what I wanted to say is, even in Western type of Toilets, there are no such problems regarding Free motion.
