Everyone probably has this habit. When you get up in the morning and use water, you often brush your teeth, wash your face, cook, and even drink tap water. Let's remind everyone
The overnight water in the faucet the next morning is best not to wash or boil directly for drinking! Instead, turn on the tap and let it water for 1 to 3 minutes. The overnight water can be collected to flush the toilet, wash the mop, and water the flowers.
Cause 1: The overnight water in the tap may harbor Legionella that causes pneumonia
Recent studies have confirmed that Legionella can be isolated from water samples from lakes, hotels, hospitals, and home water pipes. The overnight water in the taps is also likely to harbor Legionella. Once infected, people are most likely to develop Legionella pneumonia.
Legionella pneumonia: Legionella pneumonia is an infectious disease caused by Legionella pneumophila that is mainly manifested by pneumonia and may be associated with extrapulmonary system damage. The number of cases found in China is increasing day by day and has received widespread attention. Legionella pneumonia is the most serious form of atypical pneumonia, and the mortality rate without effective treatment is as high as 45%.
Reason 2: Long-term use of overnight water in tap water may cause lead poisoning
Stopping overnight taps and running water in the water pipes is static. These waters react with metal pipes and faucet metal chambers to cause hydration reaction, forming metal contaminated water, and microorganisms that remain in tap water will also multiply. Contains a lot of harmful substances.
If you use inferior taps, the amount of lead in “overnight water†will also be severely exceeded. Experts reminded that from the water meter to the pipe network of the faucet, that is, the water pipe behind the water meter is paid by the user himself.
After lead enters the human body:
Except for excretion through faeces and sweat, the rest dissolves into the blood several hours later and penetrates into the brain's nerve tissue through the blood, causing insufficient supply of nutrients and oxygen, causing brain tissue damage, leading to anemia in the human body, headache, dizziness, and fatigue. Drowsiness, constipation and limb soreness; some have metallic taste in the mouth, arteriosclerosis, peptic ulcer and retinal hemorrhage are also related to lead pollution.
If children lead poisoning, they will experience stunting, loss of appetite, inconvenience in walking and constipation, and insomnia; if the pupils are pupils, they will also be accompanied by hyperactivity, hearing disorders, inability to concentrate, and mental retardation; especially when the child is in a stage of growth and development. Lead is more sensitive than adults, and lead into the body has a strong affinity for the nervous system. Therefore, the absorption of lead is several times higher than that of adults. The degree of damage is particularly serious.
If lead enters pregnant women, it will pass through the placental barrier, affect fetal development, cause deformities, and even lead to premature delivery and miscarriage in pregnant women.
