The next night it is best not to wash or boil the water directly in the faucet, but to turn it on and let it run for 1 to 3 minutes. The overnight water that is released can be collected to wash the bathroom, wash the mop, water the flowers, etc.
Reasons why you can’t use overnight water
(1) Overnight water from faucets can harbor Legionella bacteria and cause pneumonia.
Recent studies have confirmed that Legionella bacteria can be isolated from water samples from lakes, restaurants, hospitals, and home plumbing, and that overnight water from faucets may also harbor Legionella bacteria. Once infected, people are most likely to develop Legionnaires’ pneumonia.
Legionnaires’ pneumonia is an infectious disease caused by Legionella pneumophila that is characterized by pneumonia and may be accompanied by damage to systems other than the lungs. The number of cases detected in China is increasing day by day and has caused widespread concern. Legionnaires’ pneumonia is the most serious form of atypical pneumonia, with a mortality rate of up to 45% without effective treatment.
(2) Prolonged water in drinking pipes may cause lead poisoning.
Tap water in faucets and in pipes that have been shut down overnight is static. This water reacts with the metal pipe walls and metal chambers of the faucet, creating metal-contaminated water and a proliferation of microorganisms that remain in the tap water. It contains a large amount of substances that are harmful to the human body.
If you use an inferior faucet, the lead content in the “overnight water” can seriously exceed the standard. Experts remind that the network of pipes from the water meter to the faucet, that is, the water pipe behind the meter is paid by the user himself, should choose the material.
When lead enters the body, in addition to part of the excretion through feces and sweat, another part dissolves into the blood after a few hours, invading the brain nerve tissue through the blood, making the supply of nutrients and oxygen insufficient, causing brain tissue damage, causing anemia, headache. Dizziness, fatigue, lethargy, constipation, aching limbs; some have a metallic taste in the mouth, arteriosclerosis, peptic ulcers, bleeding in the eyes are also related to lead pollution.
In the case of lead poisoning in children, symptoms such as stunted growth, loss of appetite, difficulty walking and constipation and insomnia can occur. In the case of elementary school children, it is accompanied by symptoms such as hyperactivity, hearing impairment, inattention and mental retardation. Especially when children are in the stage of growth and development, lead is more sensitive than adults, and lead enters the body with a strong affinity for the nervous system, so the absorption of lead is several times higher than that of adults, and the degree of damage is particularly serious. If lead enters a pregnant woman’s body, it will pass the placental barrier, affect the development of the fetus, cause deformities, etc., and even lead to premature delivery and miscarriage.
