Plain water acts as an "internal cleanser" for the body. Drinking 200 milliliters of fresh warm water (25°C to 30°C) 30 minutes before breakfast helps moisten the gastrointestinal tract, stimulates sufficient secretion of digestive juices to promote appetite, encourages intestinal peristalsis, facilitates regular bowel movements, and prevents hemorrhoids and constipation.Drinking water on an empty stomach in the morning is rapidly absorbed by the gastrointestinal tract into the bloodstream. This dilutes the blood, dilates blood vessels, accelerates blood circulation, and replenishes the water lost by cells overnight.
How to Properly Drink Water Upon Waking Up (Public Health Network)
What Temperature is Ideal?
Drinking lukewarm water at room temperature is best after waking up.If the weather is cold, warm water is acceptable. Water that is too cold or too hot can irritate the stomach and intestines. Cooled boiled water (20°C–25°C) possesses optimal biological activity and effectively promotes human metabolism. However, remember to cover the container when cooling boiled water overnight to prevent prolonged exposure to air, which diminishes its efficacy.
Optimal Intake Amount
Upon waking each morning is a critical time for daily hydration. At this point, expectant mothers should start with 300 milliliters of plain boiled water. Increase intake if weather is hot or physical activity levels rise.
Proper Drinking Method
Morning water must be consumed on an empty stomach to effectively flush the digestive tract and stimulate blood circulation.Drink in small sips to avoid adverse effects from rapid consumption, such as elevated blood pressure, headaches, or nausea. Contraindications for Pregnant Women ◇ Avoid water boiled repeatedly or for extended periods: Reheating increases concentrations of harmful substances like silver nitrite.When consumed by pregnant women, this can convert low-iron hemoglobin in the blood into high-iron hemoglobin, which cannot carry oxygen, leading to blood poisoning. ◇ Avoid drinking unboiled tap water: Chlorine in tap water combines with certain organic compounds to form a carcinogenic substance, making it unsuitable for pregnant women. Furthermore, even boiled water stored in a thermos for 24 hours is not recommended for pregnant women.◇ Avoid tea brewed in thermoses: Tea contains tannic acid and other compounds that can degrade vitamins and produce harmful substances when steeped in thermoses. Consumption may disrupt digestive system function in pregnant women.
◇ Consume mung bean soup in moderation: Mung beans have a cold nature and should not be consumed in large quantities over extended periods, especially by pregnant women with weak spleen and stomach functions.
◇ Avoid substituting fresh juices with commercial beverages: Commercial drinks contain high levels of preservatives, flavorings, and artificial colors, which are highly detrimental to health.
