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.
In our daily life, we have developed a lot of habits, such as, eating habit, study habit, reading habit, etc. However, taking the time to develop a sleep habit is probably the last thing on your mind and some sleep advice simply can't be forgotten. {#blank#}1{#/blank#}.
Watching TV until you fall asleep
It has nothing to do with what you watch —TV news isn't a better pre-sleep choice than TV series. {#blank#}2{#/blank#}. The bright light keeps you awake all the night. So even if you nod off (in front of the TV, for example), you probably won't stay asleep for long.
Sleeping with pets
{#blank#}3{#/blank#}. They get comfortable, and then they move. This goes on all night, and whether you admit it or not, it interrupts your ability to get the level of sleep needed to feel rested.
Eating fatty, heavy foods too close to bedtime
Heartburn (烧心，胃痛) strikes anyone of any age, but it's the most common GI disorder (胃肠失调) in older adults. If you've ever tried to go to sleep after eating a fatty meal, you've probably found the discomfort of stomach preventing you from falling asleep or staying asleep.
{#blank#}4{#/blank#}
Remember how poorly you sleep when you have a fever—turning over and over again, never really feeling rested? Well, heavy exercise too close to bedtime has the same effect — it raises your body temperature so that your sleep is disturbed until your body temperature drops to normal, which may take several hours.
Accepting snoring (打呼噜) as normal sleep behavior
Snoring may seem as common as breathing, but it's considered the biggest sleep killer, and it's linked to several causes: sleeping on your back, being overweight, having a cold, drinking, or taking drugs. {#blank#}5{#/blank#}. For the snorer, it disturbs sleep by awakening him/her every so often in order to breathe normally. For the partner, the noise can be unbearable.
A. Exercising heavily too close to bedtime B. Here are some bad habits you need to get rid of C. Most seriously, it's caused by a dangerous illness D. Here are some suggestions you'll need to follow E. Pets sleep most of the day, and they move a lot when sleeping F. Reducing your body temperature before bedtime G. Rather it's the TV's bright light that is the criminal |
