Scientists from around the world have reached a consensus on the conditions that healthy water should have through extensive investigation, statistics, research, and analysis. These conditions include:
1. No pollution, toxic substances, harmful substances, or peculiar smells.
2. Moderate hardness, referring to the presence of salts such as calcium and magnesium in water (usually around 30-200 milligrams per liter as CaCO3).
3. Moderate content of essential minerals for the human body. It is required that water contains a certain level of dissolved solid substances, including inorganic mineral components (usually around 300 milligrams per liter).
4. Water pH value > 7.0, slightly alkaline, conforming to the weak alkalinity requirement of bodily fluids.
5. Adequate dissolved oxygen and carbon dioxide content in water (dissolved oxygen ≥ 6 milligrams per liter, carbon dioxide between 10-30 milligrams per liter).
6. Small water molecular clusters (half-width ≤ 100Hz).
7. Strong physiological functions of water, including permeability, solubility, metabolic capacity, and oxidative-reductive properties.
The relationship between drinking water hygiene and human health is closely connected. Especially with the development of technology and society, drinking water is no longer just for quenching thirst, but its important physiological functions and roles are gradually being recognized.
Hydrogen-rich water generated by hydrogen water sticks contains abundant hydrogen molecules that decompose into active hydrogen within the body, which can eliminate the root cause of oxidative stress. Hydrogen-rich water can prevent and treat diseases by eliminating reactive oxygen species. Therefore, it has become known as "healing water."
Life originated in water (ocean). If there was no water on Earth 3 billion years ago, no life could have survived, and there would be no humanity today.
Water not only nurtures life but is also an important component of the structure of life. Each human body is approximately composed of 13% protein, 10% fat, 1% carbohydrates, 6% minerals such as calcium, and about 70% water. This means that two-thirds of our bodies are made up of water, and even higher levels of water are present in infants, accounting for about 80% of their body weight. Physiologically, most tissues in the human body are composed of water. The water content in various organ tissues in the human body is approximately as follows: blood 82%, muscles 76%, lungs/heart 80%, kidneys 83%, liver 68%, brain 75%, and even hard bones contain about 20% water. The human body can be said to be composed of water. We can even say that life activities revolve around water, and once water is lacking, life will cease to exist.
As the saying goes, "One can go without food for three days, but one cannot go without water for one day." According to studies by physiological experts, an average person can survive without food for about four weeks or even longer, but without water, at room temperature, one can only endure for about three days. In hot summer conditions, it may be difficult to last even a day. When the body loses 2% of its water weight, thirst will be felt.
In the beginning, when our bodies were just a single cell, we lived in water. All the chemical reactions that maintain our bodily functions are based on water. Water not only replenishes the water content in our bodies but also has a calming, cooling, and detoxifying effect.
Research has proven that each person should replenish 30 milliliters of water per kilogram of body weight per day, meaning that an 80-kilogram person should consume 2400 milliliters of water daily. Those who consistently fail to reach the standard daily intake of water are prone to stomach problems, poor skin condition, nervousness, and premature aging.
Water is the source of life and the foundation of life. This is common knowledge that everyone understands, but few truly grasp the importance of water to life and health. Therefore, some people refer to water as the "forgotten nutrient."
Scientific research shows that hydrogen-rich water generated by hydrogen water sticks has strong physiological functions such as permeability, solubility, metabolic capacity, oxidative-reductive properties, etc. Hydrogen-rich water contains abundant hydrogen molecules that decompose into active hydrogen within the body, which can eliminate the root cause of oxidative stress. Hydrogen-rich water can prevent and treat diseases by eliminating reactive oxygen species. Therefore, it has become known as "healing water."
Most people have heard or read about the functions of water, but it is perplexing that we often face the threat of dehydration. We may mistakenly believe that our body lacks water only when we feel thirsty, leading to widespread and chronic dehydration, which results in health problems. When the body has adequate hydration, blood viscosity, joint cartilage, blood capillaries, digestive system, and spinal cord can function normally and effectively. However, when water intake is restricted, the body compromises certain areas to protect different tissues and organs, resulting in pain, tissue damage, and various health issues. Adequate water intake can help resolve or alleviate certain health problems such as asthma, allergies, high blood pressure, high cholesterol, headaches, back pain, rheumatoid arthritis, angina, intermittent claudication, and more. As we age, we lose the sensation of thirst and gradually develop chronic dehydration. Our bodies need at least three cups of water every day, and alcohol, fruit juice, soda, coffee, and tea cannot truly replace water.
Expert recommendations: Drink a glass of water 30 minutes before meals, another glass 30 minutes to an hour after meals, and one more glass before a banquet or before going to bed. Thirst should be quenched with water whenever it arises. The more we pay attention to our body's water needs, the healthier we will be. Dry mouth is merely the final external signal of dehydration. In addition, many medications actually dehydrate the body and lead to serious issues. Please remember that the human body is composed of approximately 25% solid matter and 75% water. Water is a neglected but essential nutrient that can contribute to your health, vitality, and longevity.
In summary, water's importance to human physiological functions is primarily manifested through digestion, circulation, and excretion. Thus, it is necessary to have a clear understanding of the various components in water and their connection to the human body. This way, each person can truly recognize the importance of drinking water for human health. It can be said that without water, life becomes meaningless.
Scientific research has shown that "hydrogen-rich water" produced by hydrogen water sticks possesses strong physiological functions such as permeability, dissolution, metabolism, and redox. "Hydrogen-rich water" contains abundant hydrogen molecules which can break down active hydrogen in the body and eliminate the source of all diseases, reactive oxygen. Hydrogen-rich water can prevent and treat diseases by eliminating reactive oxygen. Therefore, it has become the water for treatment.
While humans can survive for weeks without food, they can only survive a few days without water. Over two-thirds of our body is composed of water. However, most people are not aware of the importance of drinking water. Water is the main medium for substance metabolism within human cells and the environment in which cells survive. Chemical reactions of substance metabolism take place in water, and metabolic products are eliminated from the body by being dissolved in water. Water's functions in the human body include maintaining cell morphology, enhancing metabolic functions, regulating the normal circulation of blood and tissue fluid, dissolving nutrients for easy absorption and transportation, aiding in the excretion of waste products, thermoregulation, and maintaining blood acid-base balance.
Water is the most abundant component in the human body and is necessary for digesting food, delivering nutrients to tissues, eliminating waste, fluid circulation (such as blood and lymphatic fluid), lubricating joints and internal organs to keep them moist. Water is a liquid containing soluble minerals, and its physiological function is similar to that of blood. It can enable substances like calcium and magnesium to reach the body tissues necessary for health.
To maintain the stability of the internal environment, the human body needs to replenish a certain amount of water daily. Under normal circumstances, the average person ingests approximately 1000-2500 milliliters of water per day through drinking water and food. Individuals engaged in heavy physical labor under hot conditions may require 3000-8000 milliliters or more water per day. When daily water intake is insufficient, the body can reduce water excretion through regulatory mechanisms. However, if water intake is severely deficient, the body's water content will decrease. When the body's water content decreases by 2% of body weight, it can disrupt substance metabolism. When the body's water content decreases by 7-14% of body weight, severe dehydration symptoms can occur. When the body's water content decreases by more than 15% of body weight, there is a danger to life.
Experiments have shown that the maximum limit of human endurance without water depends on surrounding air temperature, physical activity, and whether the person is in darkness or at rest. Under conditions of 16-23°C temperature, a person in darkness and at rest can survive for 10 days, survive for 5 days at 29°C temperature, and survive for 3 days at 39°C temperature. If a person does
