Removing toxins from your body with a little boiled lukewarm water

Have been drinking 1 Litre of water every morning empty stomach to remove toxins from my body. But it was an arduos effort. Just accidently drank water which was little warm in temperature. Just drank it effortlessly. I then understood the significance of why since ancient times, people have been advising to drinking a boiled warm water.  Just boil the water for a few seconds to a lukewarm level.
