Excuse me, can I drink the boiled water in the thermos overnight?

It's best to burn it now or just drink the boiling water of the day. Don't drink boiled water for too long or for more than 24 hours. The content of nitrite in boiled water is higher than that in raw water. In addition, if the boiling time is too long or repeated for more than 24 hours, the nitrite content will increase obviously. After standing in boiling water for 24 hours, the nitrite content is 65438 0.3 times higher than that when it was just boiled. Re-boiling drinking water will lead to excessive nitrite content in water. Excessive nitrite in water can cause fatigue, fatigue, lethargy, coma, cyanosis, blood pressure drop, abdominal pain, diarrhea, vomiting and even malignant diseases for a long time. The method of preventing and controlling boiled water pollution is simple: resolutely put an end to the reuse of boiled water and boil it repeatedly. Five kinds of undrinkable boiled water: (reproduced) 1. After burning on the stove for a night or a long time, it was already lukewarm boiled water when drinking; 2. Boiled water was boiled in the automatic water heater all night; 3. Boiling water remaining after repeated boiling; 4. The water in the thermos is not the same day; 5. boiled water left over from steamed food such as rice and meat. I wish everyone good health. . .
