Why can't the water of faucet after putting a night be used directly?
In our daily lives, we turn on faucet every morning to wash, but one important thing many people overlook is the overnight water in faucet.Why can't the water of faucet after putting a night be used directly?Normally we should open faucet in the morning, let it run for about one minute, and then use it again.
Overnight water at faucet may harbor legionella pneumoniae, the most severe form of atypical pneumonia that causes pneumonia, with a case fatality rate of up to 45 percent.Studies have shown that legionella bacteria can be isolated from the tap water pipes of lakes, hotels, hospitals, and homes, making it highly likely that legionella bacteria can be found in overnight faucet water, while legionella pneumoniae can be found in people who consume it directly.
The water in the tap water can react with faucet or the metal in the pipe to form metal-contaminated water, and microorganisms in the tap water can produce harmful substances after a night of reproduction. If the faucet used is inferior, it is more likely to cause excessive lead content in the water.
As we all know, excessive lead into the human body will destroy the human brain nerve tissue, cause oxygen supply shortage, cause brain tissue damage, resulting in anemia, headache, drowsiness and other symptoms.What's more, if it enters children or pregnant women, it will cause irreversible damage to minor children, including delayed development, malformations, premature babies and other phenomena.
So, when we get up to use faucet every day, it's best to turn on faucet and let it run for one minute, to clean the overnight water, and to keep the overnight water in buckets so that resources are not wasted.
