From the curious minds of children to the seasoned wisdom of the elderly, hydration plays a pivotal role in maintaining optimal health.

The Science of Hydration

The human body is approximately 60% water. This vital fluid is involved in numerous bodily functions, including digestion, temperature regulation, joint lubrication, and nutrient transportation. Even mild dehydration—losing as little as 1–3% of body weight in fluids—can impair mood, memory, and brain performance Healthline.

Hydration in Children

Children are particularly susceptible to dehydration due to their higher metabolic rates and smaller body sizes. According to the CDC, U.S. children and adolescents drank an average of 23 ounces of plain water daily during 2015–2018 CDC.

Recommended Intake:

Infants (0–6 months): Breast milk or formula provides adequate hydration.
Children (1–3 years): Approximately 4 cups (32 ounces) of fluids per day.
Children (4–8 years): About 5 cups (40 ounces) of fluids daily.
Older Children (9–13 years): Roughly 7–8 cups (56–64 ounces) per day.

Hydration in Older Adults

As we age, our bodies undergo various changes that can affect hydration. Older adults often have a diminished sense of thirst and may not feel thirsty even when their bodies need water. Additionally, medications and chronic health conditions can increase the risk of dehydration.

Recommended Intake:

Include water-rich foods like fruits and vegetables in your diet.
Monitor urine color—aim for pale yellow.
Limit beverages that can dehydrate, such as alcohol and caffeinated drinks.

The Risks of Dehydration

Dehydration can lead to serious health complications, including:

Heatstroke
Kidney stones
Urinary tract infections
Severe headaches
Dizziness and confusion

In older adults, dehydration is associated with increased mortality, poorer course of illness, and increased costs for health services ScienceDirect.

Hydration Strategies
