Proper hydration is crucial for optimal bodily functions, including temperature regulation, joint lubrication, infection prevention, nutrient delivery, and organ performance. Even mild dehydration can impair cognitive abilities, mood, and physical performance. Research indicates that a mere 1% decrease in body weight due to fluid loss can lead to a 5% reduction in cognitive function, affecting short-term memory and attention. Rehydration has been shown to alleviate fatigue and improve mental clarity, emphasizing the importance of consistent fluid intake for physical and psychological well-being. 

To maintain adequate hydration, experts recommend a daily fluid intake of approximately 2.7 liters (about 11 cups) for women and 3.7 liters (about 16 cups) for men, including fluids from all beverages and foods. Individual needs may vary based on age, activity level, and environmental conditions. Monitoring urine color—aiming for a light straw hue—can be a practical indicator of hydration status. 

One of the most well-known and widely referenced books on the importance of hydration is “Your Body’s Many Cries for Water” by Dr. Fereydoon Batmanghelidj. The book emphasizes that chronic dehydration is an often-overlooked cause of many health issues. The body uses “thirst signals”—frequently misinterpreted as hunger, fatigue, or anxiety—to indicate water needs. Dr. Batmanghelidj argues that many common symptoms, including joint pain, headaches, digestive problems, and even depression, may be the body’s way of signaling dehydration rather than a need for medication or food.

On a biological level, water is essential for nearly every cellular process. Each cell depends on adequate hydration to maintain membrane fluidity, optimize nutrient transport, and enable enzymatic reactions for energy production and waste removal. When hydration is lacking, cells become stressed, intracellular pH may become imbalanced, and the efficiency of biochemical processes—such as neurotransmitter synthesis and mitochondrial function—can decline. This cellular stress can manifest as systemic fatigue, mood disruption, cognitive fog, and even increased pain sensitivity.

At the neurochemical level, insufficient water intake may influence hunger and satiety signaling in the hypothalamus, the brain’s regulatory center for thirst and appetite. Because these two signals are processed in closely related regions, dehydration can often be mistaken for hunger—leading to unnecessary food intake and disrupted metabolic regulation. Additionally, hydration affects blood volume and circulation, influencing the delivery of oxygen and nutrients to the brain and other organs. This is why low water intake can contribute to lightheadedness, dizziness, mental sluggishness, anxiety, and low mood. Dr. Batmanghelidj’s work aligns with modern research, highlighting the neuroendocrine and cellular importance of staying hydrated to support physical and mental health.

Concerns have arisen regarding microplastics in bottled water, with studies detecting plastic particles in many samples. These microplastics can originate from the bottles, especially when exposed to heat or stored for extended periods. Potential health risks include inflammation and disruption of hormonal functions. To minimize exposure, it’s advisable to use reusable glass or stainless-steel containers and consume filtered tap water at a minimum, preferably Reverse osmosis (RO) filtered water. 

Reverse osmosis is one of the most advanced and effective water filtration methods available, particularly in areas with compromised or uncertain water quality. It works by forcing water under pressure through a semi-permeable membrane that allows only water molecules to pass through while blocking a wide range of contaminants—including heavy metals (like lead and arsenic), nitrates, fluoride, PFAS (per- and polyfluoroalkyl substances), pesticides, bacteria, viruses, and dissolved salts. The purified water is collected for use, while the filtered-out contaminants are flushed away as waste.

What sets RO apart from other filtration systems is its ability to remove up to 99% of dissolved solids and microscopic pollutants, thanks to its membrane’s pore size of just 0.0001 microns—far smaller than what standard carbon or sediment filters can achieve. While carbon filters are effective for improving taste and removing chlorine or odors, they do not address many harmful substances that RO systems can eliminate.

This makes reverse osmosis a gold standard for delivering clean, safe drinking water—vital for vulnerable populations such as children, pregnant women, and individuals with chronic illnesses. Its comprehensive purification capabilities effectively minimize both chemical and biological threats, offering peace of mind and improved health outcomes.

Key Contaminants of Concern

1. Nitrates

• Sources: Nitrates primarily originate from agricultural runoff, including fertilizers and animal waste. In regions like Nebraska, intensive farming practices contribute significantly to nitrate infiltration into groundwater.

• Health Risks: Elevated nitrate levels are associated with methemoglobinemia (“blue baby syndrome”) in infants, thyroid dysfunction, adverse pregnancy outcomes, and certain cancers.

• Prevalence in Nebraska: Approximately 40% of private wells in Nebraska tested over the past two years have nitrate levels exceeding 3 ppm, with about 15% surpassing the EPA’s maximum contaminant level of 10 ppm.

2. PFAS (Per- and Polyfluoroalkyl Substances)

• Sources: PFAS, known as “forever chemicals,” are found in firefighting foams, non-stick cookware, water-repellent fabrics, and more. They enter water supplies through industrial discharge, landfill leachate, and runoff from contaminated sites.

• Health Impacts: Exposure to PFAS is associated with increased risks of kidney and testicular cancers, liver damage, thyroid disease, immune system suppression, and developmental issues in children.

• Presence in Nebraska: As of December 2024, PFAS have been detected above the proposed maximum contaminant levels in three Nebraska community water systems.

3. Other Contaminants

• Additional pollutants of concern in the Midwest include pesticides, herbicides, and heavy metals like arsenic, which can leach into water supplies from agricultural and industrial activities.​​
