Why Ultra-pure(超高纯的)Water Is Actually Bad for Your Health Many people are surprised to hear that drinking purified water on a regular, daily basis is actually dangerous. So why is 100% ultra-pure water not good for us?
There is no such thing as truly pure water in the natural world. When these minerals dissolve(溶解)in water, they form what we commonly refer to as electrolytes(电解质).They allow us to perform all the "bioelectrical" functions such as moving, heart-beating, thinking, and seeing.
But pure water fails to provide these fundamental electrolytes. You can think of it this way: imagine a room with no gravity, split in half down the middle. You throw a couple hundred balls into the left side of the room. But if you cut a bunch of holes in the barrier, they will slowly start to spread over to the right side. Eventually, they will be evenly distributed across the entire room.
The water in your organs stays at very specific levels of minerals. When you drink ultra-purified water, it pulls the minerals out of your blood just like the right side of the space room pulled some of the bouncy balls over from the left.
Purified water can only be recommended as a way of drawing poisons out of the body. Once this is accomplished, the continued drinking of purified water is a bad idea.
A.Purified water is an active absorber.
B.Since there's no gravity, they bounce around everywhere.
C.It actually tries to rob your body of them when you drink it.
D.Even water in the purest lakes contains small amounts of minerals.
E.If you drank enough of it, the lack of minerals would eventually kill you.
F.The simple answer is that ultra-pure water doesn't provide the natural minerals we need.
G.This is why materials tend to move from more concentrated areas to less concentrated ones.

We all have days, or even weeks, on the job when our productivity declines. But if your output has been steadily decreasing, it could be because you're wasting time rather than focusing on key tasks at hand. {#blank#}1{#/blank#}
Turn off your cellphone
If you're eager to stop wasting time at the office, silence your cellphone. {#blank#}2{#/blank#} Turn on your phone only during breaks.
Organize your calendar
It's easy to waste time when you don't have a preset schedule outlining your days at work. But if you're guilty of not maximizing your time at the office, it'll help to create a daily calendar with blocks of time for various tasks.
Organize your space
{#blank#}3{#/blank#} If your desk is in a mess, carve out some time to get it organized. Throw away papers you don't need, file essential documents in some sort of order, and make your supplies more accessible.
Build in breaks
Sometimes we waste time at work by talking to colleagues, checking text messages, or surfing the internet because our minds need a break from the constant work. If that sounds like you, then you'd better schedule some breaks during the day but powering through otherwise. {#blank#}4{#/blank#}
The more time you waste at work, the more your manager and peers are likely to take notice– and that's a good way to hurt your reputation and put your job at risk. {#blank#}5{#/blank#} Doing so might save you from a busy night.
