In our daily life, we always turn on the faucet to wash up every morning, but many people ignore an important thing, that is, the overnight water in the faucet. The overnight water in the faucet should not be used directly for washing, even if it is boiled and used for drinking! Under normal circumstances, you should turn on the faucet in the morning and drain water for about 1 minute before use. The water can be used to wash the toilet, water the flowers, wash the floor, etc. So why can't the overnight water of the faucet be used directly?
1. The tap overnight water may contain Legionella bacteria that can cause pneumonia
Legionella pneumonia is the most serious type of atypical pneumonia, with a mortality rate of 45%. According to the research, Legionella can be isolated from the tap water pipes of lakes, hotels, hospitals and families. Therefore, there is a high possibility that Legionella exists in the tap water overnight, and once people directly consume the overnight water, they are prone to suffer from Legionella pneumonia.
2. Long-term drinking of overnight water in the water pipe may lead to lead poisoning
The water in the tap water will react with the metal in the faucet or the water pipe to form metal-polluted water, and the microorganisms in the tap water will also produce harmful substances to human body after a night's propagation. If the faucet used is of inferior quality, it is more likely to cause the lead content in the water to exceed the standard.
It is well known that excessive lead into the human body will damage the brain nerve tissue of the human body, cause insufficient oxygen supply, cause brain tissue damage, and lead to anemia, headache, fatigue and other symptoms. What's more, entering the body of children or pregnant women will cause irreparable damage to underage children, including delayed development, deformity, premature delivery and other phenomena.
Therefore, when we get up and use the faucet every day, we'd better turn on the faucet and put water for 1 minute to clean the overnight water, and use buckets to hold the overnight water to avoid wasting resources.
