As the summer heat intensifies across the country, dehydration becomes a common and potentially dangerous concern. This condition can have severe implications, particularly for seniors who are more vulnerable due to several physiological factors. Seniors face unique challenges, especially when it comes to the impact of their medication on hydration.

Why Are Seniors More Prone to Dehydration?

Seniors are at an increased risk for dehydration for several reasons:

     Reduced Thirst Signal: As people age, their bodies lose their ability to recognize thirst, making it harder to drink fluids.

     Lower Body Water Volume: Older adults generally have a lower total volume of body water, meaning they have less fluid to lose before dehydration sets in. 

     Kidney Function Decline: Kidneys become less efficient at conserving water with age, further contributing to fluid loss.

     Chronic Illnesses: Conditions such as diabetes can worsen the risk of dehydration since they affect the body's ability to control water.

 

In addition to these factors, medication plays a significant role in influencing fluid balance in seniors.

The Impact of Medication on Dehydration

As a clinical pharmacist, I've seen firsthand how medications can contribute to dehydration, especially in older adults. One of my clients, an active senior, nearly passed out while cycling in the summer. As it turned out, he was on a diuretic medication, commonly referred to as a "water pill." 

Diuretics are a class of drugs that increase urination, leading to reduced fluid levels in the body. These medications, often prescribed for conditions like hypertension and heart failure, can inadvertently lead to dehydration if fluid intake isn't carefully managed. Some commonly used diuretics include bumetanide, chlorothiazide (Diuril), hydrochlorothiazide, and furosemide (Lasix). 

But diuretics aren't the only medications that can cause dehydration. Other drugs like these can also affect your body's water balance.

     Antihistamines: Often used for allergies, these can cause dry mouth and reduced fluid intake.

     Blood Pressure Medications: Certain blood pressure medications can increase urine output.

     Laxatives: They can cause fluid loss through increased bowel movements.

     Chemotherapies: These treatments often lead to side effects like vomiting and diarrhea, contributing to dehydration.


Managing Dehydration Risks

It's important to be aware of dehydration risks, particularly for those taking medications that impact fluid balance. Regardless of whether one feels thirsty, it’s important to drink water throughout the day. Staying alert to the signs of dehydration—such as increased thirst, dry mouth, dark urine, fatigue, and dizziness—can also help address the issue early. These symptoms are early warning signs that the body may need more fluids. 

Finally, anyone concerned about dehydration should consult a healthcare provider. They can adjust medication and advise seniors on managing fluid intake to prevent dehydration.

Read on to learn about some of those benefits as experienced by older adults who appreciate the joy of laughter.Increases Immunity:A stronger immune system is one result of laughing more, supporting improved overall well-being, better blood flow and increased oxygen intake. Greater immunity helps you fight off some of the common diseases and complaints were more vulnerable to as we age.Lowers Stress:Studies show that cortisol, the bodys stress hormone, is found in smaller amounts in people who laugh more often. Lowered stress levels also lead to lowered blood pressure and reduced muscle tension, resulting in fewer aches and pains and a better nights sleep.Reduces Blood Pressure:Laughing helps improve the function of your blood vessels and increases blood flow throughout the body, lowering your blood pressure.

When the entire body is engaged, it raises your energy and makes it easier to engage with others and get up and move.Curbs Depression:Depression can affect seniors transitioning to a new phase of life, but laughter releases endorphins and can help decrease depressive symptoms. It can also help shift your focus from thoughts that lead to unpleasant feelings.As you walk the halls of Golden West, youre likely to hear laughter as residents chat with their neighbors, enjoy engaging activities and share time together in the dining room.

Aging Gracefully and Making the Most of Your Golden Years

After spending your life working and taking care of others, its important to take care of yourself as well. You want to be able to continue doing the things you enjoy for as long as possible and maintain good health. There are a variety of steps you can take and changes you can make to support healthy aging and improve your quality of life.Stay ActivePhysical activity is essential at any age. It supports weight management, strengthens bones and muscles, improves cardiovascular health, and enhances balance and mobility. You dont necessarily have to hit the gym to stay fit, though using free weights and equipment can be beneficial. Sign up for a senior fitness class, walk or bike around the neighborhood, practice yoga or Pilates, go swimming, or enjoy a rousing game of tennis. Try new activities and find things you enjoy to keep you active.Eat a Healthy DietAs you age, your dietary needs change. You may need to eat more fiber or cut back on your sodium. Create a well-balanced diet that incorporates lean proteins, low-fat dairy, whole grains, and plenty of fresh fruits and vegetables. Add a punch of flavor by experimenting with different herbs and spices rather than using salt or butter.Exercise Your BrainKeeping your brain sharp is part of healthy aging too. Spend time reading each day or doing puzzles like crosswords or Sudoku. Challenge yourself to learn new skills or hobbies. Even playing video games (and board games!) with the grandkids can work different parts of your brain and make you think and problem solve.Get Quality SleepRecovering or catching up from lost sleep can be difficult, so make it a point to try to get at least seven to eight hours of sleep each night. Keeping your room cool and dark can create a more ideal environment for rest. Pay attention to medications you take and how they may affect your ability to fall or stay asleep. Working out during the day can help you burn off excess energy and feel more tired at night.Find a Sense of PurposeGive yourself something to look forward to, whether that is volunteering in the community, attending a weekly book club, or learning to play the piano. This can help boost your mood and keep you more engaged, which is great for your mental health.Socialize with OthersThis is especially important if you live alone. Unfortunately, isolation and loneliness can contribute to depression. Make plans to have lunch with friends once a week or meet to go walking in the park. Sign up for activities or volunteer opportunities where you can connect with others while doing things you enjoy. Stay in touch with family and friends in person, over the phone, or through video calling. Surrounding yourself with people who make you happy can be very energizing.Manage Your HealthFinally, ensure youre keeping up with doctor appointments and screenings so you can stay on top of your health. Speak up if you have concerns and seek out support groups if youre dealing with chronic or life-altering conditions.Partnering with an in-home care provider can help you navigate aging with more confidence. A caregiver can support you with a wide range of activities of daily living, provide welcome companionship, and empower you to continue living your best life. Contact Always Best Care at (720) 494-8407 to schedule a free consultation and learn more about how in-home care can benefit you as you age.

Martial Arts for Seniors and the Elderly

When it comes to movement and flexibility as we age, the old adage use it or lose it definitely applies. The more sedentary a person becomes, the harder it becomes to get up and move around. This can also become dangerous, since as we lose flexibility and mobility, injuries and falls become more likely. Exercise programs as we age are a must to stay healthy and safe. But what exercise program will be enjoyable and also appropriate for your age?It might surprise you to hear that martial arts are a great choice for seniors who want to stay active and mobile. Martial arts for seniors are the perfect tool to help you stay motivated to exercise and maintain a sense of independence. Elderly martial arts also offer an opportunity to socialize in a group class setting. The Four Best Martial Arts for SeniorsTai ChiWhen it comes to martial arts for older adults, Tai Chi is an excellent choice. Tai Chi has no contact, so it is gentle, safe, and comes with very minimal risk for injury. It focuses on balance, stability, flexibility, and muscle control all things seniors need to stay healthy and injury free. Tai chi can also help reduce knee and back pain, including the pain associated with arthritis. Brazilian Jiu JitsuBrazilian Jiu Jitsu adds some light contact to your martial arts practice. Designed for self-defense, Jiu Jitsu is a great martial arts practice for older people as it gives you a sense of empowerment and self-reliance. It comes with its own special vocabulary, which will boost mental acuity while also building physical strength. It is a great choice for those who want to try contact martial arts but not put too much strain on their joints. AikidoAikido is another safe choice when looking for martial arts for the elderly since it focuses mainly on standing movements with minimal sparring. Some studios will offer a specialized aikido class called no fall aikido for seniors. Like other martial arts for old people, it will help you build confidence and learn a form of self-defense. It also helps develop the ability to stay calm in stressful or unfamiliar situations. KarateThe Japanese art of Karate is often associated with young people, but it has many benefits for the elderly as well. It is safe and easily adaptable to various skill levels. There is no age limit on earning a black belt. Martial arts are great for seniors who want to stay active but feel bored by safer or mundane activities like walking or yoga (which are both great and useful, but not right for everyone). They help increase strength, confidence, and mental health. They offer a sense of community and accomplishment, both things' seniors need as they age to stave off potential depression and loneliness. They are also just fun!As always, chat with your doctor or primary care provider before jumping into any exercise program. They may be able to offer helpful tips or information you should share with your trainer to help you modify the exercise program to keep you safe and healthy. And never be afraid to tell your trainer you need help or adjustments it is what they are there for. They also want to keep you happy, safe and injury free. To learn more about our home care services, contact our caregiving team today at 1-800-GRISWOLD
