Even if you are pregnant with a child, you are very particular about drinking water.
⊙ Drink a glass of fresh boiled water after getting up.
A study shows that plain water has an "internal washing" effect on the human body. Drinking 200ml of fresh water at 25~30℃ 30 minutes before breakfast can moisturize the stomach and intestines, make the digestive juice secrete enough to promote appetite, stimulate gastrointestinal motility, facilitate regular defecation, and prevent hemorrhoids and constipation. Drinking water on an empty stomach in the morning can be quickly absorbed into the blood by the gastrointestinal tract, which dilutes the blood, dilates the blood vessels, and accelerates blood circulation.
⊙Pregnant women should not drink water when they are thirsty.
Thirst is a rescue signal from the brain center that requires hydration. Feeling thirsty indicates that the water in the body has been imbalanced and the brain cells have become dehydrated to a certain extent. Pregnant women should drink water once every 2 hours, 8 times a day, totaling about 1600 ml.
Pregnant women cannot drink the following types of water:
l. Boiled water for a long time or repeatedly. For example, in the water in a large boiler, the concentration of harmful substances such as silver nitrite, nitrite ions, and arsenic in the water increases relatively after repeated boiling of water. After drinking boiled water for a long time, it will cause the low-iron hemoglobin in the blood to combine into methemoglobin that cannot carry oxygen, causing blood poisoning.
2. There is no boiling tap water. Because the chlorine in the tap water interacts with the residual organic matter in the water to produce a carcinogen called "trihydroxy". Pregnant women cannot drink boiled water stored in a thermos for more than 24 hours, because as the temperature of the water in the bottle gradually drops, the chlorine-containing organic substances in the water will continue to be decomposed into harmful nitrites, which is extremely unfavorable to the internal environment of pregnant women. .
3. Tea brewed in a thermos cup. Because tea water contains a lot of theophylline, aromatic oils and vitamins. If the tea leaves are soaked in a vacuum flask, a lot of vitamins will be destroyed, the tea will be bitter, and harmful substances will increase. After drinking, it will easily cause disorders of the digestive system and nervous system.
