Second, the tap water pipeline is aging and there is secondary pollution.
Third, when chlorine is added to the tap water to disinfect, the chlorine will react with organic matter in the water to produce chlorine-containing harmful substances.

These third category of harmful substances are ubiquitous in tap water or bottled water, so as long as we are in contact with water, they have the opportunity to take advantage of the void to enter our body.
So what are their ways to enter the human body?
The first way is dietary intake. In fact, it is drinking water to eat, because tap water and bottled water have them, so as long as we take them through our mouth, they can enter the body. It's a bit like a disease from the mouth.
The second way is absorption by skin contact. For example, when washing hands with tap water, harmful substances may enter the human body through the skin and pores.
The third way is inhalation. This is a bit difficult to understand. In fact, we inhale water vapor when we take a bath; in addition, when the water temperature is high, harmful substances are easily volatilized into the air. We breathe in these harmful substances; and when we take a shower, our The body also comes into contact with the skin of tap water, so the skin may also absorb these harmful substances.

Through the above analysis, we can see that when taking a shower, the amount of harmful substances in the tap water entering the human body will be the largest. Because when taking a bath, we will not only inhale it, but also skin contact and absorption, if we drink the bath water, it will still be ingested.
American scientists have specifically done relevant research and found that after 10 minutes of bathing, harmful substances (mainly trihalomethanes) will enter the human body, resulting in an increase in the content of harmful substances in the human blood, which is higher than the content after we drink 1 liter of tap water (Backer , 2000).
Some netizens will ask, I take a shower every day, what should I do now? Don't worry, we can still avoid these harmful substances.
We can shorten the bath time.
Also, don’t take a bath immediately after the first person takes a bath, because the previous person’s bath will contain harmful substances left over in the bathroom, so it’s best to wait for the air to be removed.
We can also install an exhaust fan in the bathroom to remove air containing harmful substances.
We can also replace the normal shower nozzle with a shower nozzle that can be filtered
