 Introduction of A glass of water in the morning. Introduction: Wash your face early in the morning after brushing your teeth; drink a cup of water 15–30 minutes before breakfast to supply hydration and dilute blood concentration. This habit can help prevent disease and improve appearance—it is a beneficial practice that supports longevity.

 Ancient and modern insights: There is an old Chinese saying, “Drink water upon waking; drink water before going to bed.” Drinking water early in the morning and washing your feet before bedtime are time-honored health practices—recognized by modern medical science as sound components of a healthy lifestyle.

 A glass of water in the morning 03 Water is one of the seven essential nutrients for the human body. Traditional Chinese Medicine (TCM) holds that water promotes Yang Qi and unblocks meridians and collaterals. Modern medical science indicates that water constitutes the primary component of human tissue; in adults, approximately 60% of body weight is water. Body metabolism requires water to proceed effectively—indeed, water is the spring of life. Drinking adequate water daily helps transport nutrients, lubricate tissues, regulate body temperature, aid digestion and absorption, facilitate waste elimination, and maintain acid-base balance in bodily fluids. Especially upon waking in the morning, consuming an appropriate amount of water offers numerous health benefits.

 A glass of water in the morning. The first cup of water in the morning is best consumed on an empty stomach—ideally 15–30 minutes before breakfast—for optimal effect. Otherwise, benefits such as improved circulation and gastrointestinal cleansing may not be fully realized. Drink slowly, in small sips. About 300 mL is ideal. Avoid juice, cola, soda, coffee, milk, or other beverages—even in hot summer, salted boiled water is not recommended as the first drink of the day. Freshly boiled water is preferable: warm water in winter; in other seasons, boiled water cooled naturally to 20–25°C is suitable, as it gently stimulates gastrointestinal function.

 Better alternatives include honey water and lemon water. Honey water provides hydration and some nutrients, and may also help relieve constipation—but it is unsuitable for individuals with gastric disorders. Drinking a cup of warm boiled water with a fresh lemon slice on an empty stomach in the morning not only helps balance the body’s internal pH but also aids in clearing old fecal matter, eliminating toxins, and freshening breath. People with cold-damp constitutions may opt for ginger–brown sugar water to boost Yang Qi.

 
Benefits of a glass of water in the morning:

 A glass of water in the morning 04 ✵1. Promotes diuresis: Drinking water on an empty stomach early in the morning stimulates urine production, helping eliminate metabolic toxins and waste products accumulated overnight. For those taking medication, this habit supports timely urination—reducing drug side effects—and facilitates gastrointestinal cleansing, stimulating peristalsis, moistening the intestinal tract, softening stool, promoting endotoxin excretion, and preventing or alleviating constipation.

 ✵2. Enhances skin health and supports weight management: Morning water is readily absorbed and distributed throughout the body, aiding blood purification and circulation, hydrating the skin, and imparting a supple, radiant appearance. Adequate hydration also elevates basal metabolic rate, facilitating fat oxidation and supporting healthy weight management.

 ✵3. Boosts alertness and mental clarity: Water consumed upon waking is rapidly absorbed through the intestinal mucosa into the bloodstream, effectively increasing blood volume, diluting blood viscosity, improving circulation, and enabling the brain to return swiftly to wakefulness—energizing you for the day ahead.

 A glass of water in the morning 05 ✵4. Supports hydration and disease prevention: The first cup of water replenishes fluids lost overnight through metabolic activity. It is quickly absorbed by the empty gastrointestinal tract and helps dilute blood, urine, gastric juice, bile, and other secretions—thereby reducing risks of hypertension, atherosclerosis, angina, cholecystitis, gastroenteritis, urolithiasis, and urinary tract infections.

 ✵Tips: Elderly individuals often experience diminished thirst sensation due to reduced responsiveness in the brain’s thirst center. Many older adults are therefore insensitive to thirst—meaning they may already be dehydrated by the time they feel thirsty. This can lead to dry skin and increased wrinkles. Hence, older adults should proactively hydrate—not wait for thirst cues.
