Does exercise sharpen your memory? How long do the benefits last? New research

Most of us have forgotten where we put our phones or car keys or what we ate for dinner last night. We’ve walked into a room and wondered why we even walked in there in the first place. A sharper memory helps us retain the information we’ve learned and remember what’s important. We’re always hearing about this superfood or this special drink or supplement that can boost memory, and we wonder if there’s any merit to many of these claims. 

With all the benefits of exercise, from lowering blood pressure to perking up your mood, researchers wanted to explore if exercise could boost memory and how long these benefits last. If working out is effective, how many hours or days do those short-term cognitive benefits last? Does working out the day before improve your memory the following day? Let’s look at the new research.

The study

In a small study published in the International Journal of Behavioral Nutrition and Physical Activity, researchers analyzed data from 76 adults. Participants were aged 50 to 83. Over eight days, participants took daily cognitive tests and wore activity trackers.

Researchers revealed that participants who engaged in more moderate to vigorous physical activity performed better in memory tests the following day. The adults who had better scores on the memory tests:

Moderate activity can include brisk walking, cycling, or jogging. Participants who spent more time being sedentary performed worse on the tests.

This isn’t the first study to associate exercise with a better memory, and it certainly won’t be the last. Research has shown that moving your muscles enhances your neuronal activity, which refers to the chemical and electrical signals generated and transmitted by neurons in your brain. Previous studies found that people had better results on memory tests in the hours following exercise, but researchers weren’t sure how long these positive effects stick around.

Interestingly, researchers in one study determined that high-intensity interval training or HIIT and cycling were the types of exercise most likely to enhance memory, executive function, attention, and information processing.

Why does exercise improve recollection and cognition?

Researchers and experts believe exercise can improve memory and cognition by increasing blood flow and stimulation of neurotransmitters. Neurotransmitters help transmit messages between nerve cells to assist memory and thinking. Exercise can also prompt the hippocampus to form new neurons. The hippocampus in your brain plays a big role in your learning and recollection. 

Neuroplasticity of the brain

Research highlights that exercise promotes neuroplasticity in the brain. Neuroplasticity refers to your brain’s ability to adapt and form synaptic connections, particularly in response to learning, experience, or after an injury.

The takeaway

Spending less time sitting and getting a minimum of 6 hours of sleep every night is beneficial for your mental faculties and overall health.  If you get a good workout in the day before, your mind and memory could be sharper the following day. It turns out that working out really could enhance your memory, at least for the next 24 hours, which is worth keeping in mind if you have a big presentation or test coming up. The research is mounting.

Gym member’s shocking hair loss proves why exercise equipment hygiene is so important: ‘I’m so scared’

This is a warning for all avid gym-goers.

Fitness enthusiast Hillary Nguyen recently shared a video on TikTok describing the health crisis she dealt with after interacting dirty gym equipment.

“PSA to all my gym girlies, if you’re not wiping down every single piece of equipment before you use it you’re gonna want to start,” Nguyen said, per Daily Dot, in a clip shared on the now-defunct video-sharing platform.

“Three months ago I discovered that I had scalp ringworm and it literally made go bald,” she explained

Nguyen continued, “That same day I went to the doctor’s and they did a black light test on me and that’s how they discovered that it was ringworm. She asked me if I go to the gym and I said basically every day, so that was most likely why.”

In another video, Nguyen said that her scalp improved after three months of treatment.

Nguyen’s first video had over 40,000 likes and over 491,000 views on Saturday before TikTok was shut down that night following a temporary federal ban on the app.

Viewers weighed in on her PSA about gym sanitation in the comments section.

“I sanitize my phone with alcohol wipes and wash my hands right after the gym. I’m so scared to catch something!!! No one wipes stuff down at my gym,” one person wrote.

Another said, “Well new fear re-unlocked. I do wipe all equipment but this was like not an active conscious thought about ringworm avoidance til now.”

Someone else commented, “I got ringworm from the mats at my gym a while back it sucked! Def bring wipes and disinfectant if you can [i know] some gyms don’t keep up with it like they should.”

According to the American Academy of Dermatology Association (AAD), people are at risk of getting ringworm at the gym.

“This is because bacteria, viruses, and fungi that cause skin infections to develop, thrive in warm, moist places like sweaty exercise equipment and locker room showers,” the AAD’s website says.

The AAD recommends several tips for preventing skin infections at the gym, including wearing loose-fitting, moisture-wicking clothes, always wearing shoes, disinfecting equipment before and after using it, washing or sanitizing your hands immediately after working out, and showering as soon as possible.

Sports Column: Finding the time to exercise in winter is difficult – The Vicksburg Post

Sports Column: Finding the time to exercise in winter is difficult – The Vicksburg Post

Sports Column: Finding the time to exercise in winter is difficult

Published 4:00 am Sunday, January 19, 2025

Like a lot of people, I made a New Year’s resolution to exercise more, lose a little weight, and get into shape.

All right, “resolve” might be a strong word. Let’s call it a desire to get a little more value for my $50 a month gym membership than the once-a-month visits that became the norm in 2024.

For a while I’ve been stuck in the fitness paradox. When starting a regimen your muscles hurt after a workout so you want to rest, but the more you exercise the less they’ll hurt. Give it a couple of weeks and you’ll power through it.

It’s one of the biggest hurdles to getting into shape, and one I was reminded of again this week. I hit the pool for a modest 2,000-yard swimming workout, my first since Christmas, and had to grind hard to finish the last half of it. If I’d been in the water a couple times a week it would not have been nearly as taxing.

Time and work are big obstacles to exercising, of course. Especially this time of year. Getting home at 5 or 6 p.m. as the sun is setting and the temperature is dropping limits the neighborhood walks that are an easy way to burn calories. Covering a basketball game at Vicksburg High once a week and trekking up the hill from the parking lot in the dark isn’t going to cut it.

Another roadblock, for me at least, is other people.

I’m primarily a lap swimmer, so access to an indoor pool is the main reason I joined my gym. Unfortunately, it also means everyone else has access.

Besides other lap swimmers, that pool is used for children’s lessons and water aerobics classes.

When you lap swim you can’t see what’s in front of you — you look down, not ahead — so you’re trusting other people to watch out for you. Young kids trying to stay afloat have bigger concerns than avoiding you, so you need to develop a high level of ESP to avoid smashing into them like a torpedo into the side of a destroyer. It’s stressful.

The water aerobics folks have been nice and friendly when we’ve crossed paths — maybe a little too friendly. They tend to hang out and float for a while after their classes and get chatty. I don’t want to be rude, but also don’t want to swap life stories and recipes when I’m trying to stay on an interval and in rhythm.

The water aerobics folks have also scheduled thrice-weekly evening classes from 6 to 7 p.m., which is primetime for a post-work workout. I have to leave work early and go in the middle of the afternoon, or squeeze in a late swim and hope the gym managers don’t decide to lock up early.

Getting forgotten about and trapped in the pool overnight is a weird but not irrational fear, right?

I know there are more forms of exercise than swimming, and I probably need to explore those and stop making excuses. Hit the exercise bike or treadmill, for crying out loud. Lift a weight heavier than a 12-ounce Coke can.

Or just complain and rant. That burns calories, too.

Exercising regularly is important for preventing dementia. But if it’s hard to rack up the recommended amount of activity during the five-day work week (150 minutes of moderate-intensity activity, like brisk walking, or 75 minutes of vigorous activity, like swimming), consider the “weekend warrior” approach — fitting it all into one or two weekly sessions. The approach might offer the same brain health benefits, according to a study published online Oct. 29, 2024, by the British Journal of Sports Medicine. Researchers analyzed the health and self-reported activity information of more than 10,000 dementia-free people in Mexico who were followed for about 16 years. After accounting for factors that could influence the results, such as lifestyle habits, scientists found that weekend warriors were 13% less likely to develop mild cognitive impairment (MCI), a precursor to dementia, compared with people who didn’t exercise — about the same benefit seen in those who exercised during the work week. While the study was observational and can’t prove cause and effect, it supports the idea that even less frequent exercise might help protect brain health, and it might be a more convenient option for busy people.
