Can you wash your face and brush your teeth when you turn on the tap in the morning?
When you get up in the morning, you often take the tap water to brush your teeth, wash your face and cook, and even drink tap water directly.
The overnight water in the faucet the next morning is best not to be used directly for washing and boiling! Instead, turn on the tap and drain the water for 1 to 3 minutes before using it normally. The overnight water released can be collected to wash the bathroom, mop and water the flowers.
Legionella causing pneumonia is likely to be hidden in the overnight water in the faucet
Recent studies have confirmed that Legionella can be separated from water samples of water pipes in lakes, restaurants, hospitals and families, and Legionella is also likely to be hidden in the overnight water in the faucet. People are usually infected with Legionella pneumophila by breathing water mist from water sources polluted by Legionella.
Once people are infected with this Legionella pneumophila, they are very likely to get Legionella pneumonia.
Legionella pneumonia
Legionella pneumonia is an infectious disease caused by Legionella pneumophila, which is characterized by pneumonia and may be complicated with other system damage outside the lung. At present, the number of cases found in China is increasing day by day, which has attracted widespread attention. Legionella pneumonia is the most serious type of atypical pneumonia, and the mortality rate without effective treatment is as high as 45%. The disease can be an outbreak.
Late summer and early autumn are the most common seasons for this disease, with males suffering more than females, and pregnant women, the elderly and the immunocompromised are the high-risk groups.
Typical patients with Legionella pneumonia often have subacute onset, fatigue, weakness, myalgia, chills, fever, etc.
After 2-1 days incubation period, the patient may suddenly start to get sick, with high fever, chills, headache and chest pain, and then cough becomes worse, with a small amount of bloodshot or bloody phlegm in the cough. The amount of sputum is small, but it is generally not purulent; < P > The early symptoms of this disease are obvious, about half of them have abdominal pain, mostly watery stools.
neurological symptoms are also common, such as anxiety, mental retardation and depression.
with the progress of lung diseases, respiratory failure may occur in severe cases.
Long-term drinking of water in water pipes and faucets overnight may lead to lead poisoning
Faucets and tap water in water pipes that are stopped for one night are still, and these water will have hydration reaction with the metal pipe wall and the metal chamber of the faucet, forming metal-polluted water, and the residual microorganisms in tap water will also multiply, which contains a lot of substances harmful to human body.
If inferior faucets are used, the lead content in "overnight water" will seriously exceed the standard. At the same time, experts also said that the pipe network from the water meter to the faucet, that is, the water pipe behind the water meter is paid by the user himself, and the materials should be selected.
After lead enters the human body:
Except part of it is excreted through feces and sweat, the rest dissolves into the blood and invades the brain nerve tissue through blood after several hours, which makes the supply of nutrients and oxygen insufficient, causing brain tissue damage, leading to anemia, headache, dizziness, fatigue, drowsiness, constipation and limb pain. Some mouths have a metallic taste, and symptoms such as arteriosclerosis, digestive tract ulcer and fundus hemorrhage are also related to lead pollution.
If children suffer from lead poisoning, they will suffer from developmental retardation, loss of appetite, inconvenient walking, constipation and insomnia.
Pupils are accompanied by hyperactivity, hearing impairment, inattention, mental retardation and other symptoms;
Children, in particular, are more sensitive to lead than adults, and lead entering the body has a strong affinity for the nervous system, so the absorption of lead is several times higher than that of adults, and the degree of suffering is particularly serious.
if lead enters pregnant women, it will pass through the placental barrier, affect fetal development, cause malformation, and even lead to premature delivery and abortion.
