As the first generation raised with modern technology begins to enter their golden years, scientists are starting to uncover how decades of tech use may impact brain health—and the results are surprising.

A new study published in Nature Human Behavior reveals that regular use of technology—like smartphones, computers, and the internet—may lower the risk of developing cognitive decline, including conditions like dementia. In fact, researchers found that tech-savvy seniors were 42% less likely to experience cognitive impairment compared to their less tech-involved peers.

The study, a meta-analysis from two Texas universities, examined 57 research papers involving over 411,000 adults—mostly aged around 68. Researchers wanted to test the “digital dementia hypothesis,” which claims that relying on technology weakens the brain over time. Instead, the results point toward the opposite: thoughtful tech engagement might strengthen cognitive resilience.

“The effects remained strong even after factoring in things like income, education, and lifestyle,” said Dr. Jared Benge, a neuropsychologist at UT Austin’s Dell Medical School and co-lead author of the study.

While social media use showed mixed results, none of the studies reported an increased risk of cognitive decline from technology use. That’s a level of consistency that experts call “rare” in this kind of research.

Well, yes—but with a few caveats. Experts emphasize that this doesn’t mean endless scrolling on your phone is suddenly healthy.

“Our findings aren’t an endorsement of mindless tech use,” Benge said. “But they do show that engaging with tech tools can provide some cognitive benefits—especially for the generation that helped build the digital world.”

And it’s not just about swiping through apps. Learning how to use new devices or navigating unfamiliar programs can provide powerful mental stimulation. That effort is what researchers say may help preserve brain function as we age.

While the results are encouraging, the study also had limitations. It didn’t track how long or how people were using their devices. Was it brain-teasing activities like problem-solving and communication, or more passive scrolling and streaming?

“We don’t yet know how much is too much, or what types of tech engagement are the most helpful,” said Dr. Christopher Anderson, a neurologist at Brigham and Women’s Hospital in Boston.

That’s partly because technology has evolved so quickly. The types of tech used 20 years ago required more effort—think dial-up internet and early desktops. Today’s tech is often faster and more passive, so it’s unclear if future generations will experience the same benefits.

The study leans toward the “cognitive reserve” theory, which suggests that mentally stimulating activities—like using tech—can build up resilience in the brain. This reserve can help buffer against age-related decline and even mild forms of dementia.

Tech can also foster social connections, which are crucial for mental health. Loneliness, on the other hand, has been consistently linked with a higher risk of cognitive decline.

Even though the study didn’t pinpoint exact best practices, experts do have some guidance:

• Use tech in moderation. Overuse can still cause issues like eye strain or neck pain.
• Engage meaningfully. Seek activities that involve creativity, learning, or connection—like video calls, online classes, or puzzle games.
• Mix it up. Combine tech use with offline activities such as reading, walking, or socializing in person.
• Don’t be afraid to learn. Even older adults with mild cognitive issues can benefit from learning to use new devices, and that mental challenge can be a healthy brain workout in itself.

“Too much of anything can be a bad thing,” said Dr. Amit Sachdev, a neurologist at Michigan State University. “But purposeful tech use that stimulates, connects, or educates? That’s a win.”

We often hear a lot about how frequently people should poop, with experts suggesting that it varies depending on various factors. But what about urination? How often should you pee, and what does your frequency say about your health?

How Often Should You Pee?

According to Dr. Jamin Brahmbhatt, a urologist at Orlando Health, the average person should urinate about six to eight times a day. Ideally, you shouldn’t be waking up at night to pee, but if you find yourself getting up more than once, it could be an indication that something isn’t quite right. During the day, it’s normal to pee every three to four hours.

However, some people may urinate up to 10 times a day, especially if they’re drinking a lot of water or beverages that stimulate frequent urination, like coffee, tea, or alcohol. These drinks can have diuretic effects that irritate the bladder. Dr. David Shusterman, a board-certified urologist, advises those bothered by frequent trips to the bathroom after drinking these beverages to cut back on caffeine or alcohol, or try diluting them.

Everyone’s body is different, and there’s no “one-size-fits-all” rule. What’s most important is knowing what’s normal for your body. If you suddenly find yourself running to the bathroom much more or much less than usual, and it’s affecting your daily life, it might be time to check in with a doctor.

Excessive Urination: What Could Be the Cause?

If you’re urinating more than usual and it’s not related to your beverage intake, several medical conditions could be to blame. Overactive bladder syndrome, diabetes, urinary tract infections (UTIs), or medications like diuretics (commonly prescribed for high blood pressure) can cause excessive urination.

Urination is controlled by a complex neurological system involving the bladder, urethra, and brain. Conditions that affect this system, like stroke, spinal cord injuries, and neurological diseases such as Parkinson’s, multiple sclerosis, and even tumors, can also lead to frequent urination.

Pregnancy can also contribute to more frequent urination since increased fluid intake and metabolic changes put more pressure on the bladder. In addition, stress and anxiety can stimulate the bladder, increasing the need to pee, as the body releases adrenaline during the fight-or-flight response.

For women, hormonal changes — especially during menopause — can affect urination. Reduced estrogen levels can lead to an overactive bladder. Dr. Jason Kim, a clinical associate professor of urology, explains that estrogen receptors are present in the bladder, which is why treatments like vaginal estrogen creams can be beneficial in managing overactive bladder symptoms.

When to Seek Help

If you notice that your frequent urination is affecting your quality of life, or if you’re waking up at night to pee regularly, it may be time to consult a urologist. They can help determine whether bladder training exercises or other treatments, such as medications, bladder Botox injections, or nerve stimulation, are necessary.

Bladder Botox, for instance, weakens the bladder’s nerves to reduce involuntary contractions and decrease the urge to urinate. This can be far more effective than medications for many patients.

Not Peeing Enough: What Does It Mean?

On the flip side, if you find that you’re only peeing every six to eight hours or less than four times a day, this could be a sign of dehydration or a problem with your bladder or kidneys. Low urinary frequency can increase your risk of developing a urinary tract infection (UTI), as regular urination helps flush out harmful bacteria.

If you’re not urinating often, make sure you’re getting enough fluids. The National Academy of Medicine recommends that women consume 2.7 liters (91 ounces) of fluids daily, and men should aim for 3.7 liters (125 ounces). This includes all fluids and water-rich foods, like fruits and vegetables.

If you’re holding it in too long, this could cause long-term damage, leading to kidney infections or weakened bladder muscles. If you are still not urinating enough despite maintaining healthy hydration, it’s time to see a doctor.

Why Aren’t You Peeing Enough?

Not urinating frequently enough could indicate an obstruction, such as a blocked urethra, or it could be a behavioral issue, especially for men as they age and experience prostate enlargement. For women, a tightened urethra could contribute to retention issues.

Neurological conditions like those mentioned earlier can also affect urinary function.

Treatment for Infrequent Urination

Unfortunately, there are fewer treatments available for underactive bladder. Depending on the cause, treatment options include self-administered catheterization, long-term catheterization, or sacral neuromodulation — a procedure that involves a bladder pacemaker to regulate urination. These treatments can be life-changing, so if you’re dealing with underactive bladder issues, don’t hesitate to seek help.

Conclusion

Your urination frequency can be a key indicator of your overall health. Whether you’re peeing more or less than usual, it’s important to understand what’s normal for you and take action if something changes. If you’re concerned, speak to a urologist who can help you get to the root of the issue and find an appropriate solution.
