Everyones heard the old saying Use it or lose it.There is some truth to thatadage: Our brain has a wonderful ability to adapt and changeeven as we age. This ability is called neuroplasticity, and it means that we can keep learning for as long as we want to. But just as with any other muscle, our brain needs regular exercise.

According toexperts, agood brain workoutis one thatis a bit challenging and teaches you something new. Maybe youve always wanted to try your hand atphotographyor throwing a pot. Or maybe youre planning a trip toItalyand youd like to brush up on your Italian.Have youbeen working on your memoirs?You could join a class to get tips on how to organize yournotes,andshare your journey with others. If you long for something moreenergetic,there are many types ofdance classes. Any activitythat keeps you challenged and focusedwillstimulate your brain andimprove your memory.

Manylifestyle factors affect memory. Experts recommendtakingthe followingstepsto improve memory andbrainhealth:

Get regular physical exercise.The best thing for memory is exercise, says RickHuganir, PhD, director of the Johns Hopkins Department of Neuroscience.Researchers arenot clear exactlyhowit works, butit has to do withgetting more blood to your brain.Physical exercise also helps prevent diseases that can be damaging to memory, such as diabetes and hypertension.

Aerobic exercise is the best kind: if its good for your heart, its good for your brain,is a good mantra to follow.Try takingexercise breaks throughout the day, whether you are still working or retired; even a few minutes of getting your heart rate going will help reboot your brain. Activities that require hand-eye coordination (such asany racket sportandmany dance classes) are particularly good for the memory circuits.

Housework and yardworkmayalsocountas aerobic exercisesometimes.Also, if youre pressed for time,you coulddo a power walk through the grocery storeor the mall and complete errands at the same timeas youfill yourexercise quota.

Handle any medical problems,especially circulatory diseasessuch as high bloodpressure,highcholesterol, diabetes, and strokeall ofthese conditions can damage the brain and affect your memory.A nationwidetrialcalled the Sprint-Mindstudyshowed that intensive lowering of blood pressurereduces the risk for mild cognitive impairmentwhich isa risk for dementia.Hormone imbalance in both women and men, including thyroid problems, may also be of concern.

Get enough sleep. Sleep apnea and stress are two sleep disruptions that can damage brain functions, includingmemory.Experts believe that 95% of adults need 7.5 to 9 hours of sleep, whereas many of us are getting by on 6 or less. Sleep is necessary for the essential function ofmemory consolidation,which occurs only in the deepest stage of sleep. Youmay haveheard some orall ofthe following suggestions before, but they really are the best way to begin sleeping more and better:

Turn off all screens at least an hour before bed; the blue light emitted by TVs, phones, and computers causes wakefulness and interferes with the hormones that cause sleepiness, such as melatonin.
Go to bed and get up at the same time every day, even on weekends and holidays.
Cut back on caffeine if you suspect that it's interfering with your sleep. People react differently to caffeine;you may beso sensitive that even one morning cup of coffee can keepyoufrom sleeping at night,or it may haveno effect at allon you.


Review your medicationswith your doctor; some, such as anxiety meds, can affect memory. Other medications may also have side effectsthat affectmemory as well asother brain functions.Your doctor should also check for possible drug interactions.Be sure to also tell your doctor about any supplements that you take regularly.

Stay social!Crosswords and sudoku are great for keeping you sharp, butitseven bettertoplay Bridge, Scrabble, or other challenging games with friends.Keeping your memory healthy is as good an excuse as any for getting out and getting together!Now that more and more people have been vaccinated, social rules in more places are being eased somewhat. A 2008 studyfrom the Harvard School of Public Health found that people with the most active social lives had the slowest rate of memory decline. Remember to get your hearing tested at least yearly, as it often declines gradually and can contribute to social isolation.

Manage your stress. Stress is not something you can avoid; in fact, stress is a part of life. Rather than try to avoid stress itself, the key is to look at how you react to it,physically and emotionally. Over time, poorly managed stress reactions can destroy brain cells, damaging the areas in the brain that deal with memory, making it harder to make new memories or retrieve older ones. Here are a few ways to manage stress:

Learn to meditate.Meditation is easy to learn and has wonderful benefits, both physical and mental.Besides helping you with daily stress relief, meditation can help improve memory and focus, and reduce anxiety. On the physical side, a regular meditation practice has been scientifically shown to help with chronic pain, high blood pressure, and diabetes.
Learn to say No.If your to-do list is one of the sources of your stress, take steps to shorten it.
Learn how to play. Finish this saying: All work and no play If you can learn to bring joy and spontaneity back into your life, you might feel a little happier and more relaxed.
Simplify. Step outside the Rat Race and slow your life down a bit. If you can stopor at least reducemultitasking, youll enjoy the peaceful Zen feeling of focusing on one thing at a time.


Laugh more. Laughingand responding to funny situations or jokes requires several areas of the brain to work together, stimulatinglearning and creativity, according toHelpGuide. Laughter also relaxes you physically, by alternately tensing and relaxing your facial and stomach muscles. Dose yourself with your favorite radio or TV comedyshows, orlook up on-demand programs on cable. As the saying goes, Laughter is the best medicine!

Eat healthy.Is there a memory diet?Not exactly. But some foods are better for a healthy brain than others, and some foods aredefinitely NOTso good for your brain. The best overall diet, as you probably know, isbased on fruits, vegetables, whole grains,healthy fatsolive oil, nuts, fishandlean protein. Here are some additional pointers:

Getomega-3 fatty acids, either fromcoldwaterfatty fish such as salmon, trout, herring, andtuna;or from walnuts, flaxseed, winter squash, pumpkin seeds, kidney beans, and soybeans.
Limit calories from saturated fatit increases the risk of dementia and impairs concentration andmemory.
Eat more fruitsand vegetablesthey are full ofantioxidants, important in protecting brain cells from free radical damage, thus improvingmemory.
Drink green teait containspolyphenols, which protect against free radical damage and may enhance memory andalertness.
Have somered wine (in moderation), or grape juice, or eat fresh grapes and berriesall of these containresveratrol, an antioxidant which boosts blood flow tothebrain and in doing so may improve cognitive function, including memory, according to several recentstudies.

The Impact of FTRI Specialized Phones: Enhancing Communication for Floridians

Since 1991, Florida Telecommunications Relay, Inc. (FTRI) has improved the lives of Floridians experiencing hearing loss and speech impairments, through its specialized telecommunications Equipment Distribution Program (EDP). Established by Floridas Telecommunications Access Systems Act (TASA) in response to the passage of the Americans with Disabilities Act of 1990, FTRIs EDP oers an array of devices designed to bridge communication gaps.  Per TASA, a monthly 7-cent surcharge on landline phone bills covers the cost of FTRI distributed equipment, and the Florida Relay Service.  By providing equipment at no cost to consumers, FTRI is empowering individuals to lead more independent lives while remaining connected to the world. Let's take a look at several FTRI specialized devices and explore some heartwarming client stories that illustrate their profound impact on everyday lives.   Understanding FTRI Specialized Phones   FTRI specialized equipment caters to a range of communication needs. The devices include amplified phones, cell phone amplifiers, captioned telephones, text telephones (TTYs), and alerting devices. Each type is engineered to address specific needs:   1.     Amplified Phones: These phones are equipped with volume controls that can amplify sound significantly, up to 50 decibels, making it easier for individuals with hearing loss to understand conversations. They also feature tone settings, loud speakerphones, back-lit buttons, and loud ringers.2.     Cell Phone Amplifiers: Amplifiers use Bluetooth technology to wirelessly   pair with smart phones (Android, iPhone).  These portable, rechargeable devices allow a user to enjoy many of the same features found on standard amplified phones, such as volume and tone controls, hearing aid compatibility, and loud speakerphones.   3.     Captioned Telephones:  These devices display real-time captions of the conversation on a large screen, helping those with severe hearing loss to  read what the other party is saying.  Screens can be customized to a users preference, and call transcripts can be saved for future review.   4.     Text Telephones (TTYs): TTYs allow individuals with hearing or speech impairments to communicate via typed messages.   5.     Alerting Devices: These include flashing lights and loud ringers to alert individuals to incoming calls.   Transformative Client Stories   Jack and His Amplified Phone   Jack, a 75-year-old retired teacher, began experiencing hearing loss a few years ago. As his hearing deteriorated, he found it increasingly difficult to keep up with phone conversations, particularly with his grandchildren who live out of state. The frustration of missing out on these precious interactions led him to seek help from FTRI.   Upon receiving the Clarity XLC8, John noticed an immediate improvement. The adjustable volume and tone controls allowed him to customize each call. For the first time in years, he could clearly hear his grandchildren's voices. The device not only restored his ability to communicate, but also brought immense joy back into his life, through an improved connection with his loved ones.   Dave and his Cell Phone Amplifier   Like so many other Floridians, Dave disconnected his landline years ago.  He relied on his iPhone to make all his phone calls. Over time, however, he found himself using texting to avoid making calls whenever possible, because the iPhones volume was simply not loud enough for him to hear conversations clearly.   Daves daughter reached out to FTRI with questions about the Clarity XLCgo Cell Phone Amplifier, hoping it might be easy enough for her father to operate.  Both father and daughter were delighted to learn that the XLCgo connects to smart phones by Bluetooth quite easily, and is designed to be used both at home and on the go.  Once Dave had paired his iPhone to the XLCgo and realized he could once again enjoy conversations over the phone, there was no looking back for him.   Maria and Her Captioned Telephone   Maria, a 62-year-old librarian, was diagnosed with profound hearing loss, which made phone conversations nearly impossible.  This posed a significant challenge in her life, where communicating over the phone was essential for both personal and professional reasons.  Feeling isolated and frustrated, Maria turned to FTRI for a solution.   FTRI provided Maria with a captioned telephone.  This device transformed her ability to communicate. The real-time captions allowed her to read conversations, ensuring she could understand every word spoken.  Saving call transcripts for future reference became routine for her, especially for calls with her doctor to discuss medications. The captioned phone improved her life by restoring her sense of independence, safety, and competence.   Sam and His TTY Device   Sam, a 45-year-old software developer, was born with a severe speech impairment. Communicating over the phone was always a daunting task for him, often requiring the assistance of a family member or colleague. This dependency made Sam feel self-conscious and restricted his ability to handle personal and professional matters independently.   FTRI introduced Sam to a TTY device and the Florida Relay Service, which revolutionized his communication experience.  The TTY allowed Sam to type his messages, which were then converted into voice for the person on the other end of the line by the Relay Service.  Likewise, he received typed responses that he could read. This device gave Sam the autonomy he craved, enabling him to manage personal communications without assistance. The TTY device empowered   Sam, boosting his confidence and fostering a greater sense of independence. The Broader Impact of FTRIThe stories of Jack, Dave, Maria, and Sam are just a few examples of how FTRI specialized phones are transforming lives across Florida. By providing these devices at no cost, FTRI is removing financial barriers that might otherwise prevent individuals from accessing essential communication tools. This initiative is fostering inclusivity, ensuring that everyone, regardless of their impairments, can stay connected with the world around them. Moreover, FTRI's eorts extend beyond just providing devices. The organization also oers training and support to help users get the most out of their specialized phones. This comprehensive approach ensures that individuals are not only equipped with the necessary tools but are also confident in using them eectively. To learn more about FTRIs Equipment Distribution Program, visit www.ftri.org, or call 800-222-3448.

How Heat Affects Older Adults and Ways to Stay Safe

When temperatures rise, older people are among those most likely to become sick and die from the damaging effects of heat. Of the estimated 12,000 people in the U.S. who die from heat-related causes each year, 80 percent are over age 60. Its clear that senior adults are most vulnerable to the stresses of heat. This article will explore how heat affects older adults while offering ways to stay safe during the heat waves of summer.Why Older Adults Are More Vulnerable to HeatBiological factors play a role in the dangers of high temperatures when youre over 60. Even if youre healthy, it can be difficult to discern when its too hot or that youre becoming dehydrated. This means you may be slower to take measures to protect yourself from the heat or intake more fluids.To make matters worse, as you age, your body holds more heat as temperatures increase. This is because your glands dont release as much sweat as when you were younger, so your internal cooling system isnt as effective or efficient. Additionally, your blood circulation diminishes with age, which means less heat is released from your blood vessels through your skin.Medications can also make you more heat intolerant as an older adult. If your doctor makes you aware of this and offers insight in how to manage this side effect, the problem can be overcome. You dont necessarily have to choose between your medication and heat safety.What Are the Signs of Overheating for Older Adults?You may experience several of these symptoms when you are overheated:Sudden dizzinessHeat crampsSwelling your legs or anklesHeat exhaustionHeath StrokeHeat exhaustion happens when your body can no longer cool itself. You can address the situation by removing yourself to a cool environment, loosening your clothes or putting on cooler clothes. You can also try taking a cool bath. Some people find it helpful to drink a sports beverage that contains electrolytes. This can hydrate your body more rapidly than water alone.Symptoms of heat exhaustion include:ThirstDizzinessWeaknessStumbling, becoming uncoordinatedNauseaIncreased sweatingCold, clammy skinRapid pulseHeat stroke surpasses heat exhaustion and is a medical emergency. If you suspect a heat stroke, call 911 immediately. Get to a cooler place and put on cooler clothes. Do NOT have anything to drink, as this could make the problem worse.Symptoms of a heat stroke include:FaintingIncreased body temperature over 104 degrees FahrenheitDry skinStrong and rapid pulseOr a slow and weak pulseNo longer sweating (even though its still hot)Heat Safety Tip #1: Avoid the OutdoorsIts best to avoid direct sun and stay inside an air conditioned building when its especially hot outside. Try planning your outdoor activities for early in the morning and finish by 10 a.m. If morning isnt ideal, you can plan to be outdoors as the sun starts to set. Otherwise, stay where there is air conditioning. If you dont have air conditioning or cant afford it, spend some time in places that do, especially when there is a heat wave. You could read a book at the library, walk at an indoor mall, or meet your friend for ice coffee.Heat Safety Tip #2: Stay HydratedThis is another obvious one, but it can also slip your mind if youre not making an effort to pay attention to your fluid intake. Ensure you drink plenty of cool or cold water, clear juices, electrolyte drinks, or anything that is alcohol and caffeine free. Both alcohol and caffeine are diuretics that expel fluid from your body. They counteract hydration.Most experts agree that you should drink one-third to one half your body weight in ounces each day. During the summer, its best to drink at the higher end of the range to prevent dehydration.Heat Safety Tip #3: Dress for the WeatherIts best to wear looser, light-colored clothes that are also lighter in weight. These materials are more breathable, so they dont trap heat. And the lighter colors reflect more of the suns energy rather than absorbing it like darker colors. Its also a good idea to wear a broad-brimmed hat if youre in the sun.Heat Safety Tip #4:Use SunscreenUse broad spectrum sunscreen that is SPF 15 or higher. You may choose a lotion or a spray, but whats most important is that you apply it liberally to all sun-exposed skin. While youre aware that sunscreen helps protect your skin from damaging UV rays and sunburns, you might not realize that it can also help prevent heat exhaustion and heat stroke.Heat Safety Tip #5: Apply Cool WaterWhen youre feeling too warm, take a cool (but not too cold) shower or bath. This can help to regulate your system and bring relief to the discomfort. If youre short on time or have another reason for not wanting to get completely wet, you can apply cool, wet washcloths to key areas like your wrists, ankles, neck, and armpits.Be Aware and Proactive This SummerThe best way to beat the heat this summer is to be conscious of outdoor temperatures, sun exposure, and your own bodys reactions. Remember that you may not recognize your overheating until you are already dehydrated or experiencing heat exhaustion symptoms. So its best to stay proactive and be sure youre dressing for the heat, staying hydrated, using sunscreen, and applying cool water when needed.TYE Medical offers premium incontinence products in a variety of sizes and absorbency levels.

Swimming with Incontinence: How to Enjoy the Pool or Beach with a Leaky Bladder

Most people love being near water during the hot months of summer. Relaxing by the pool or on the beach is a favorite summer pastime. But if youre living with bladder incontinence, your favorite warm-weather activities may become a burden. The idea of wearing swimwear can cause anxiety as you consider the consequences of leaks and worry about disguising your incontinence products.While these are legitimate concerns, swimming with incontinence while maintaining peace of mind is possible. Here are some tips for the best wet n wild summer yet.Dont Stress About Small Leaks While SwimmingLight bladder leaks are no problem whether youre swimming in the ocean or a pool. Its completely harmless to yourself and others. Even people without incontinence empty their bladder in the ocean (not that its recommended).In either case, its best to empty your bladder before entering the water. This will buy you some time without any concern about leaks. This is especially important when swimming in a pool. When urine mixes with chlorine it can irritate skin. Small leaks may not be an issue, but larger leaks can cause problems for yourself and others.If your leaks are larger, its important not only to empty your bladder before swimming, but also to wear incontinence swimwear.Buy Quality Incontinence SwimwearIts critical that you dont wear any incontinence products into the water that arent specifically designed for that purpose. Typical incontinence aids are created to absorb liquid and will absorb the water around you until they burst or break. Remnants of the product can clog pool filters and be harmful to marine life if youre swimming in the ocean. All of this can be quite embarrassing and is avoidable.Instead, purchase incontinence swimwear that is specially made to wear in the water. Just be sure that the swim product is the right fit and absorbency level for you to prevent any unfortunate accidents. These products are made to absorb urine from the inside while not taking on water from the outside.Just be sure to change out of your incontinence product for swimming when you leave the water. You can swap your swim product for your regular leak protection until you swim again.Try Other Incontinence Devices for SwimmingYou may prefer to temporarily use an incontinence device while swimming. The two common devices are the pessary (for women) and the penile cuff (for men).The pessary device is inserted into a womans vagina and applies pressure against the urethra, stemming the flow of urine. Its like a tampon but serves a different purpose. It isnt suitable for everyone and may be too uncomfortable, especially at first. Some women prefer this because its discreet and simple. A pessary temporarily reduces leaks to a minimum and gives you great freedom while swimming.The penile cuff compresses a mans urethra so that little to no urine passes through. It is placed about halfway down the penis, and similar to the pessary, greatly reduces the flow of urine. But these should only be used on a short-term basis and must be released every one to two hours, according to the manufacturer.This device isnt for everyone, even though most men report that after the initial adjustment period, they became accustomed to the device and found it relatively comfortable. For some men, using the device is preferable to not swimming or dealing with incontinence swimwear.Both the pessary and penial cuff have side effects if you wear them too long or dont use them correctly. Before using them, get some advice from your primary care doctor or your urologist.Watch What You Eat and Drink Before SwimmingBefore and during your pool or beach outing, you want to avoid irritating your bladder with foods and beverages that arent agreeable. Bladder irritation can make bladder leaks worse or cause overactive bladder.Before and during your water activities, avoid caffeine, alcohol, spicy foods, and acidic foods. Instead, stay hydrated with water and opt for snacks that are easier on your bladder. This will ensure you stay comfortable and dont experience unnecessary bladder leaks while swimming or relaxing by the water.Enjoy Your Summer (Even with Incontinence)Incontinence doesnt mean you must stop living. Summers can still be an enjoyable and memorable time of the year. But a fantastic summer requires some planning ahead and maybe even a few changes to the norm. But were confident it will be worth the effort as you enjoy a relaxed and fun summer.TYE Medical offers premium incontinence products in a variety of sizes and absorbency levels.
