How does drinking hot water cleanse your system?

I've heard people say that drinking hot water is better for you than drinking cold water because the hot water cleanses your body. But how is that possible? Because I would think that whatever you drink would become the same temperature as your stomach once it gets there. It's not like that ice cold water is going to go all through your veins.How does drinking hot water cleanse your system?
My understanding is that the hot water is not magic, but that cold water slows the digestive process, and helps flem collect. I switched to hot water last year, and I noticed a difference, especially in the winter. I use RO filtered water warmed in a tea kettle. My GI system feels real good now.How does drinking hot water cleanse your system?
Purposely drinking hot water means for most people an increase in total daily water consumption, I would imagine. Drinking more water helps by lubricating your gastrointestinal tract - your intestines extract water from your digested food and then reinsert water to lubricate your faeces as required. Adequate water consumption enables your kidneys to filter wastes better and maintains blood volume; your neurological system also benefits from adequate hydration - the next time you have a mild headache, try having a few glasses of water and wait half an hour before grabbing for paracetamol (acetaminophen? in America).





Anyway, I got off the track - you are correct of course when you say the temperature would equalise in the body. The only benefit I can think of for hot over cold water consumption is that maybe there would be less energy expenditure to bring hot water down to body temperature than cold water up? Think of it this way - it's probably easier for heat to dissipate than for it to be generated. There may also be a calmative effect in the act of stopping to concentrate on drinking a hot beverage that (atypically) contains no sugar, fat or colouring.
I can't see any difference, besides, whats the difference between that and drinking hot tea, coffee, or cocoa?
