Hydration for Seniors: Why Water Intake Is Crucial for Healthy Aging

Water sustains life. It controls body temperature, lubricates the joints, transports nutrients and aids almost all the biological processes. However, in case of the seniors, hydration is an even greater important factor, a factor that may make or break the difference between being active or exhausted, alert or disoriented, self-sufficient or unable.

As we grow older, our body stops working in our favor, as dehydration grows more frequent and deadly. The cues that used to remind us to drink water become less pronounced, the kidneys lose their ability to preserve the water, and drugs or other chronic illnesses disrupt the water balance in the body.

It is not only the knowledge of the amount of water the seniors need to consume. It is about the realization of how the old age impact on the body hydration system, how to make sure that the body does not get dehydrated in the first place, and makes practical and fun habits that will keep the elderly healthy, alert and independent. Understanding the unique senior hydration challenges is the first step.

This guide will explain it all, how aging affects the process of water in the body and the daily hydration practices and preventive measures. It also relates you to other guides on elderly dehydration drinks, hydrating food that can be taken by seniors, and the way that caregivers can ensure that the older population stays hydrated. For those dealing with electrolyte imbalances, learn about electrolyte drinks for seniors.

The reason we should be more concerned with Hydration as we age.

The body contains water approximating 60 percent, however, the percentage reduces as individuals grow older. When a person is in their 70s or 80s, the total body water may reduce to half or even less. This implies that there is lesser reserve fluid in case dehydration starts and therefore a slight imbalance can cause massive consequences.

In young adults, it may be mild fatigue due to the lack of a few glasses of water. In elderly patients, the same amount of dehydration may lead to confusion, dizziness, low blood pressure, or urinary infections that may rapidly turn into severe health complications.

The Aging Body Role of Water.

Water helps almost all aspects of the senior health:

• Brain Processing: The brain uses water to keep the concentration and communication within the cells. Dehydration may cause brain fog, moods, and reduced reaction time.
• Heart Health: Adequate hydration maintains the blood pressure constant and prevents potentially fatal drops.
• Digestive: the elderly frequently have constipation because of low fiber consumption, decreased mobility, or medication. Water assists in the waste removal within the digestive system.
• Kidney Health: One of the most commonly occurring causes of urinary tract infections (UTI) and kidney stones in the elderly is dehydration.
• Muscle and Joint Function: Water adds cushioning to joints and maintaining the muscles pliable to prevent stiffness and falls.
• Skin and Immune System: Hydration helps the body to aid in the regulation of temperature and prevention of illnesses through a healthy skin.

Everything is literally impacted by hydration including memory and balance, to mobility and mood.

The Key to Aging and Thirst and Kidney Function.

There are two major variations that put the elderly at higher risk of dehydration: a less sensitive feeling of thirst and a decreasing ability of the kidneys.

Reduced Thirst Sensation

The thirst mechanism of the brain of the elderly becomes less sensitive. Hypothalamus, which checks the hydration levels of the body takes more time to signal thirst. When elderly people are already dehydrated their bodies, they say, "I do not feel thirsty." (Note: This is a known issue - the thirst sensation becomes less sensitive with age.)

This is the blunt type of thirst, whereby seniors are able to lose a third or even a quarter or their natural hydration awareness and as such drinking water constantly and not when thirsty is necessary.

Reduction in the efficiency of the kidneys.

Kidneys naturally become weak with time. Once they reach the age of 60, their concentration of urine reduces and this implies that they lose more water despite the body making efforts to retain it. Therefore, the elderly might lose fluid more quickly than they can imagine and in particular when they are not taking fluids regularly.

Medication and Health Conditions.

Most elderly people include drugs which make them lose more fluids like diuretics, laxatives and blood pressure medications. There are also other cases of chronic diseases such as diabetes or heart disease that also impact water balance. These medications can also deplete electrolytes, making it essential to understand which electrolyte drinks are best for seniors to help maintain balance.

Mild dehydration can be dangerous in these conditions as it exacerbates fatigue, alters the circulation, and reduces the effectiveness of medications.

This article provides an overview of reliable information on the importance of hydrating the elderly and the challenges involved in determining the appropriate amount of water to drink.

Subsequent Symptoms of Dehydration in the elderly.

Older adults are usually caught by dehydration. The symptoms might be so mild and most of them can resemble other conditions that could be common at the age. That is why caregivers, relatives, and medical professionals should remain vigilant to the warning symptoms.

Early Symptoms

• Dry mouth, lips, or tongue
• Dark yellow or reduced output of urine.
• Fatigue and weakness
• Headache or mild dizziness
• Constipation
• Dry, cool skin
• Confusion or memory lapses

Advanced Symptoms

• Rapid heart rate
• Sunken eyes
• Low blood pressure
• Muscle cramps
• Trouble walking steadily
• Severe disorientation or drowsiness.
• Loss of consciousness

Mental changes can be observed even in mild cases of dehydration. Research indicates that the dehydration of the body by as little as 2 percent will slow down attention, reactions and working memory, all important activities in independent living.

Whenever a senior feels unusually disoriented or sleepy one of the first questions to be always asked is: Have you had enough to drink today?

Awareness of the risk factors for dehydration among older adults serves as an effective measure to avoid the condition and prevent unnecessary hospitalizations caused by dehydration (National Prevention Council, 2011).

Water Requirements of the Elderly, Daily.

The overall principle of older adults is consuming approximately 1.5 to 2 liters of fluids daily, or approximately 6-8 cups. Nonetheless, this amount is not predetermined. The water requirements are subject to numerous preferences:

• Body size and muscle mass
• Activity level and climate
• Medication use
• Long-term diseases such as kidney or heart disease.
• The consumption of dietary salt and caffeine.

The Estimation of the Individual Needs.

One rule is to consume 30-35 milliliters of water per kilogram of body weight. As an illustration, the estimated amount of liters required by a 70 kg individual would be 2.1 liters (approximately 8-9 cups).

A Simple Hydration Formula

• Morning: 1 glass when one woke up.
• Meals: The number of meals is one glass per meal.
• Noon: One glass between dinner and lunch.
• Evening: little gulps after dinner.

The elderly who are not fond of plain water can add back herbal teas, watered down juice, or flavored water to make it more palatable as a source of hydration.

The reason why many seniors do not take enough water is why.

There are a number of behavioral and psychological causes of dehydration among elderly:

• Fear of Incontinence: Most elderly people restrict water usage because they do not want to go to the restroom frequently and especially during the night. Ironically, it increases the chances of bladder irritation and infections.
• Mobility Problems: The inability to walk or rise might deter drinking.
• Forgetfulness or Cognitive decline: Elderly patients with dementia do not always remember to drink or feel thirsty.
• Bad Taste: There are drugs that make the mouth taste metallic and this makes water unattractive.
• Loss of Appetite: Elderly people with lower frequency of eating also consume less water as food constitutes some of the daily hydration.

Knowledge of such barriers can guide caregivers to develop reasonable plans to maintain constant hydration.

Ultimate Hydration and Prevention Strategies.

Seniors do not just need hydration. It involves establishing a setting and a habit that will allow one to be hydrated without struggling- by incorporating fluids, foods, and habits that will fit into everyday living.

Serve a Selection of Hydrating Beverages.

Plain water is most appropriate but many of the elderly consider it dull or distasteful. Other alternatives available are:

• Infused water: slice up lemon, cucumber or mint and infuse the water.
• Herbal teas: Teas that are caffeine-free such as chamomile or hibiscus hydrate and relaxing to the stomach.
• Milk or fortified plant-based milk: The hydration is one that contains protein and calcium.
• Broths and soups: This is fine in colder weather or when one has lost any appetite.
• Electrolyte beverages: Useful to the elderly who take diuretics or sweat too much. For detailed recommendations, see our guide on electrolyte drinks for seniors.

The seniors need to drink electrolyte drinks that have lower sodium, potassium, and magnesium content. Learn more about elderly dehydration drinks to find safe and effective options.

Eat Water-Rich Foods

Food supplies about 20 percent of daily intake of hydration. The elderly who have difficulty in taking enough fluids can increase their consumption of hydrating foods like:

• Stone: watermelon, oranges, peaches, strawberries, grapes.
• Vegetables: celery, tomatoes, lettuce, cucumbers, zucchini.
• Soft products: Yogurt, smoothies, soups, and oatmeal.

Fluids are also a good option to use with elderly persons who have difficulties in swallowing food or experience decreased thirst.

Hydrating foods are eaten by the older generation to improve the body capacity to assimilate the food and fluidary matter.

Develop a Hydration Schedule.

Routine builds consistency. The elderly do have their way and caregivers can assist in creating more routine practices.

Practical ideas:

• Have a glass of water or a bottle of water within your reach at all times.
• Take medications with a little bit of water.
• Create alarms or smart gadgets.
• Label water bottles with time objectives (8 am, 10 am, etc.) to time water consumption during the day.
• Combine water consumption with current routines (brushing teeth or television).

This is the case since in most cases, the elderly people are not able to realize the need to stay hydrated in their bodies.

Calculate Weather and Activity Adjustments.

The levels of hydration require rise in hot weather or light exercises, e.g. walking or gardening. Elderly lose water by sweat and breathing despite not feeling hot.

Sip and swallow in small portions instead of gulping in big portions to prevent bloating or discomfort.

Measure Hydration periodically.

Straight forward examination is urine color: a pale yellow color means that a person is well hydrated whereas dark yellow or amber means that a person is dehydrated.

Caregivers are also able to check the change of weight (a sudden loss of more than 1-2 pounds per day can be some indicator of fluid loss).

Visual cues are beneficial to the seniors who are less aware. It is possible to have a glass jug of water at hand or colored cups that can become soft reminders.

The Relation Between Water and the Brain.

Among the side effects of dehydration among the elderly, one should not ignore its influence on the brain. The slight amount of fluid loss impacts mood, concentration and memory.

It has been found out that dehydration may:

• Raise the chance of delirium and confusion particularly when ill.
• Decrease vigilance and weakens response time.
• Add to depression and tiredness.
• Affects the metabolism of medications that influence the brain chemistry.

This is because rehydration can restore mental clarity in a matter of hours. In the case of seniors, particularly those who stay alone or in nursing homes, frequent water intake can be seen boosting the mood and consciousness.

The researchers developed a literature review to determine common pathways of hydration and cognitive impairment in elderly people.

Medication Safety and hydration.

Water affects the absorption and processing of drugs. Some of the drugs are likely to be concentrated in the blood without enough fluids, which enhances side effects.

Common examples include:

• Painkillers (NSAIDs): In dehydration there is an increase of the risk of the strain of the kidney.
• Blood pressure drugs: May cause too low pressure in the case of low fluids.
• Laxatives: Have the potential to increase dehydration unless taken together with sufficient water.

Ask the elderly to use a full glass of water to take medications unless the doctor specifies otherwise.

The hydration of elderly individuals is influenced by medication, as is the reverse (Related: [How Medication Affects Hydration in Seniors])

Hydration in various Living Conditions.

The requirement of hydration also relies on the location and the residence of the seniors.

At Home

Get water within reach: place water close to the body, get light weight bottles, and make water-giving foods.

In Assisted Living

The staff members are supposed to arrange frequent periods of hydration in the form of pre-meal, activity, and medication rounding periods. Use hydration charts to monitor the intake.

In Nursing Home or Hospitals.

Fluid intake logs are common in medical teams. Caregivers may also represent seniors through ensuring that fluids are served in high frequency and preferences recorded.

The target population is elderly people and their immediate caregivers living in assisted living and nursing homes respectively.

When to Seek Medical Help

In case of a severe case of dehydration like confusion, fainting or no urine over 8 hours or more, then seek medical assistance. Oral hydration may be insufficient in such situations; the intravenous fluids may be required to restore the balance safely.

Aging people should pay attention to the medical prescriptions prescribed by the doctor, as in other instances, overhydration may also be dangerous. Personalize hydration plans at all times and with advice of a professional.

A good book on rehydrating fluids in older people is that written by Ripley and Dore (2000); it is not organized as a book but it contains a plethora of sub-topics divided by sub-headings.

Conclusions: The Simple and the Strong Water.

The hydration of the elderly is not merely a health tip but a key to a long life and a healthy one. Aging has an impact on the process with which the body utilizes water, however, it does not reduce the body water requirements.

By making minor daily routines, older adults will be able to significantly enhance their:

• Energy levels
• Mental clarity
• Mobility and joint comfort
• Medication effectiveness
• Overall quality of life

One of the easiest, cheapest, and most efficient methods of aging well is proper hydration. It does not need fancy supplements and expensive beverages but merely perseverance, consciousness and attentiveness.

The promotion of hydration is not just about avoiding dehydration, but a better life on a daily basis.
