I heard a lot of people said if water keep been reboil is bad to be drunk because the minerals in it somewhat became toxic. Then those machine like Coway or Cuckoo they have a separate tank in it especially for hot water, so it will kept refilling the tank, does that means the water inside keep on been reboil?

then it is bad to be drink right?

yes if the tank is made of plastic

Nah. Semua benda nak suap.

A quick google can get you the answer you want

no harm for reboil

If it is bpa free container with food grade standard, should be no issue.

but but.. people around me dont boil water again in the electric kettle. They just tuang the water away and refill and boil.

If people around you eat shit, you also say eat shit is good?

it all boils down to your convienience.

Lu nak ikut stupid around, ikut lah.

Why bangang buka thread?

but shit smells badly, how can people eat something that smells badly?
i see. sound right also

Try googling Smelly Tofu

oh no... i didn't see this coming. You win already. Because i love eating it

At least we have something in common, I love it too

1) there is no concrete evidence it's bad o not
2) even if got negative effect, the effect is very minimal
3) technically, the best water to drink is normal filtered water, as it contained the most nutrient
4) u can boil & process until bcom super clean distilled water (air suling) & still drinkable, but it no longer has any nutrient benefits

either way, just drink whatever water that ur body can accept.
for me, i either just boil tap water, or filtered tap water.
no need fancy coway or diamond gimmick for me.
imo, processing & breaking down the water molecule or making the water too clean will slowly weakens your immune system.
that's y many people when go india, dink their water, straight stomachache, while the local drink like bause without issue.

conclusion, drink water that still has nutrient value. dun drink water that is too super clean, as it weakens your immune system.

but do you reboil the tap water?

My kettle, up to me how many times I want to reboil the liquid inside.
if die then die, not then not, we all will die eventually I rather die satisfied.

you boil, no boil, re-boil water.. you will still die after years of drinking water.

after years of eating rice, you die also. same of anything you do in your life.

I see... Thank you

it depends.
at home, got filter, straight drink direct from filter.
if wanna make hot drinks, need to boil lo.
sometimes got left over som water in kettle, i then i need to make hot water again, just straight top off & boil again.
provided the water is still clean by looks & less than 2-3 days.

Same as drinking 8 glasses of water a day.. It's a myth.

my morning coffee water in my man-cave i boil like 5 times every week (too lazy to replace water before going to work). I am still alive.

oddly enough, my wife used to scold me for this things too. I guess wimmin just thinking too much

urban myths TS, don't follow bad science

woah i see. THank you so much for the tips

Wait, this is a myth as well?

The effect will slowly come mah.. just like smoking, takkan smoke 1 year and 2 year then become worse mehhh haha

Damn.. i thought i am the only one.. so glad to know i am not alone.. I am the victim tu...

But some people follow and sounded me

Sound that back with facts

refer to the post below. Some people cannot sound back one.

I understand liao.. at least i know i can reboil water for my own convenience

As long as you dont boil it down twice.

No. Logically : does not make sense.

Try googling to confirm your theories based on RCT studies.

So you don't waste electricity/gas.

If water is left boiled too long or is reboiled, the chemical compounds change for the worse. By leaving your water to boil down, you’re actually concentrating many harmful chemicals instead of getting rid of them … The same thing happens when you reboil water, as the compounds concentrate and increase the risk of ingesting certain chemicals.’

this one is funny

let say that water got 100ppm of TDS or 4.5ppm iron

how come reboiling makes the said contents increase

raining down from langit or what?

i think the writer got confuse with concentration increase and the chemical contents in water itself

The water that we get has went through so many places, encountered different chemical, bacteria, etc.

The water then went through syabas for filtration and etc.

What the water went through before coming to you has been worst by thousand or millions time compared to reboiling.

then reboil soup also the same

boiling off

means the water become less and less

then add more water, boil it off again

like this the tds will increase

but no one the world want to do that la

Don't scare me

Those pipu say so due to living with caveman.

Org kite dulu say no good keep boiling because they wanted first hand water. Not leftover even though it is as good as new.

So make it less obvious they say cannot re-boil.

When want hot water, they will get new “fresh” hot water.

So boiling the water over and over won’t kill.

Reboiling can reduce the chlorine in the water.

ayy

really? so its watered-down?

I see English comprehension is not your forte?

Klau semua x elok hang dok hutan ja la

Ayam not mat salleh

And you still alive

Yea... Amen.

Everyone who drinks water die eventually. It's a strong enough evidence that eater is poisonous

First you need to state whether you are boiling filtered water or unfiltered tap water.

1. Filtered tap water
Most filtration system are reverse osmosis. This removes almost completely the minerals. Boiling almost pure water over and over again gives you pure water.

2. Unfiltered tap water
Reboiling increases the concentration of the minerals due to loss of water molecules as steam. Is the amount of mineral consumed harmful? That depends on your overall diet. It might even be a supplement for your deficiency in rare cases.

Wow very legit . I like you

People also say Kangen can cure cancer, so u belip or not

You know that it's just water right? Well I suppose if you want to become the hulk you can boil it using a nuclear reactor

Yes reboiling water twice or more may increase the water temperature above 100 Celsius. Thus it may cause fire and ur whole house might burn down.

reboil or not its irrelevant mostly
what is the container that the water boil in, initially or reboil that matters the most

I see what you did there

one or two times no harm. the harm comes when you reboil it excessively

I guess the believe in ghosts too?

Chemist here

If you’re using a metal kettle, reboiling the same water is fine as there is no changes in the water chemistry.

However there are some precautions for plastic kettles as it uses heat resistant plastic, plastic nonetheless will have some traces of chemicals in the water. That’s after you boil the same water multiples times anyway. So you’ll be fine even if you reboil the same water 2-3 times.

Don't buy into those nutrients mineral natural super healthy kukubird grow 10 times nonsense. You are not living in extreme condition that every amount of nutrients are so precious.

Eerrrrr
So its fine or not to boil miltiple times?

Side note, mat sallehs says y asians so weird boil water, but they are ok drinking hot coffee lel

It does have an effect when you're using it to make coffee.

I used to reboil the leftover water in my electric kettle all the time to make coffee.

After a while I was wondering why my coffee taste sucks even though it should be the same.

After some goggling, found about using "fresh-boiled water".

Since then I always readd some water to leftoever water before boiling it. Taste of coffee back to normal.

Thank you so much
