We often reach for water in hot and humid weather to quench our thirst. While many of us opt for ice-cold water to cool down, water closer to body temperature can actually be more effective for hydration. The variety of water available offers numerous benefits, from replenishing fluids to aiding in waste removal. Although we often think of all water as just bottled water, there is a surprising range of types to consider.
Water Classified by Hardness
Water is categorized based on its hardness into soft water and hard water. Soft water includes distilled water, rainwater, and tap water, commonly used for beverages like tea or coffee. Hard water, conversely, refers to mineral-rich groundwater or healthy water. Consuming hard water can sometimes lead to digestive issues, such as stomach upset or diarrhea, so it’s wise to be cautious.
Drinking Spring Water
The most popular bottled water is often referred to as spring water. This type of water is sourced from natural underground springs or aquifers and is treated to ensure it remains clean and safe to drink. It is valued for its natural purity and the ability to maintain its quality over time.
Alkaline Ionized Water
Alkaline ionized or electrolyzed water passes an electric current through regular water, such as tap water or groundwater. Electrodes in the water attract different ions: negatively charged ions gather at the positive electrode, creating acidic water, while positively charged ions collect at the negative electrode, forming alkaline water. According to the South Korea Food & Drug Administration, alkaline water is often sought for its potential health benefits, such as aiding digestion and alleviating chronic diarrhea.
Want to Combat Aging? Try Oxygen Water
As we age, the oxygen transported through our blood decreases, which can contribute to skin aging. Drinking oxygenated water, which is enriched with dissolved oxygen, can be beneficial. This water is absorbed into the body more quickly than oxygen from breathing, potentially improving blood circulation and assisting in waste removal, which can help maintain youthful, elastic skin.
Mineral Water: Spring Water
Mineral or spring water is drawn from natural springs and is rich in minerals like calcium, magnesium, and potassium. These minerals are essential for various bodily functions, including growth, maintenance, and regulation of pH levels. Since the body cannot produce these minerals, consuming them through mineral water can be beneficial.
Carbonated Water
Carbonated water contains dissolved carbon dioxide, which creates bubbles and can lead to frequent burping. Although some believe this helps with digestion, it does not directly affect digestive processes. Frequent consumption of carbonated water may contribute to issues like acid reflux and does not relieve constipation as some might think. People with irritable bowel syndrome (IBS) should also avoid carbonated water, as it may worsen their symptoms.
Deep Ocean Water with Rich Nutritional Value
Deep ocean water, or deep-sea water, is sourced from depths greater than 656 feet (200 meters) where sunlight cannot reach. Due to its cold temperature of around 36°F (2°C) and the lack of mixing with other seawater, this water is rich in beneficial inorganic nutrients and minerals. After desalination, it is salt-free and contains more minerals than typical bottled water.
Pure Water: Distilled Water
Distilled water is produced by cooling and condensing steam to produce highly purified water. Due to its purity, it is often used in research. Because achieving pure water with a single distillation can be challenging, it is commonly categorized into first, second, and third distillations to ensure higher purity levels. Distilled water is essential in purifying and separating substances and is utilized across various scientific and industrial fields.
Even Slight Dehydration Can Cause Thirst
Our bodies are about 70% water; even a 1-2% decrease in hydration can lead to thirst and an increased risk of illness. Losing more than 10% of body water can be life-threatening, so staying hydrated is crucial. As we age, our bodies experience increased water loss, and our need for hydration grows. Regular daily water intake is essential for maintaining overall health.
Which Type of Water is Best for Me?
With the wide variety of water types available on the market, each with its unique characteristics and benefits, it’s important to choose based on your needs and preferences. Consider the composition and source of the water and select the one that aligns best with your health goals and current condition.
