The Results Are In: Exercise Improves Memory And Learning. But How?

By Beth Shelper

Here at Innermost, we’re all about looking after your health: body and mind. So when we heard about this (may we say, ground-breaking) study published in the Proceedings of the National Academy of Scientists, we just had to shout about it.

The results are in: exercise improves memory.

That settles it then. As if you needed more reasons to exercise, a recent study has confirmed that small amounts of exercise can improve memory function. How neat is that?! This exercise / memory study has shown that there are a range of exercises to improve memory and concentration, answering the age-old question in the fitness (and neurology) world: can exercise improve memory?

Ground-breaking exercise memory study: the details

So, here’s the 4-1-1. The exercise and memory retention study was conducted in 2018, and it’s results have revealed that exercise (even mild exercise) can improve memory function. Not only that, but these mild exercises can improve memory function… immediately!

Researchers at the University of California have recently found that light exercise increase the connectivity between the parts of the brain that are responsible for memory: both formation and storage, suggesting that we should all be implementing exercise into our daily lives (if we don’t already…)

Who was involved in the exercise and memory retention study?

We all know that the results of a study are only as trustworthy as the study’s methods, so don’t worry: we’ve done a deep dive to get the nitty and gritty out of this investigation.

The study involved thirty-six adults (all of whom were not reported to have any health issues and were young). The study involved scientists monitoring the participants’ brains after a short, ten-minute stint of exercise, to monitor brain activity and the functioning of the brain’s different areas, to determine the effect (if any) on exercise and memory retention.

Warning: scientific language incoming. After these ten minutes, researchers studied the thirty-six participants and found that there were far greater connectivity levels between the Hippocampal Denate Gyrus (aka, the area of the brain that creates our memories), and the Cortical areas, that are responsible for memory processing. Truly incredible stuff.

Not only is this a pretty monumental finding, but our Hippocampus is one of the areas that sees the greatest impact of deterioration as we age, so any research that provides opportunities to slow down (or even stop) this awful side effect of aging is more than welcomed by us here at Innermost (and by you, we’re sure).

Does this prove that exercise improves memory?

If you’re still not convinced, stick around. We’ve found some more studies to back up the science, so there should be no doubt in your mind by the end of this article. None at all.

The results of this 2018 exercise and memory retention study reinstated the results of a slightly older study conducted in 2011. The 2011 study, published in the Proceedings of the National Academy of Sciences of the United States of America, or PNAS - for short, found that in a randomised (but controlled) trial with 120 adults, aerobic exercises such as running, swimming and walking reversed the hippocampal volume decrease that is synonymous with memory loss (and old age).

Exercise improves memory and learning. Fact. Case closed.

If you’re anything like us, you’re probably looking for some quick ten minute exercises to slot into your day now, correct?

Well, because you asked so nicely…

Our favourite exercises to improve memory and concentration

If you’re someone that spends a lot of time sat down at a desk (aka, a very large proportion of us), It’s super important to be getting up and about every hour to ensure you’re staying active (and improving your memory!)

Here are some of our favourite, short (and mild) exercises to help you stay active:

  • Star jumps (or jumping jacks, for our American friends)
  • Marching (on the spot, if you’re limited for space)
  • Wall sits
  • Lunges
  • Side lunges
  • Step ups
  • Seated knee-to-chest
  • Seated leg extensions
  • A brisk walk

Summary

Can exercise improve your memory? It absolutely can: you can’t argue with the science.

The Truth About Electrolytes
Electrolytes. You’ve seen the word plastered across sports drinks, hydration tablets, and wellness blogs. You know they have something to do with hydration and performance. But do you really need them? Or is this just another overhyped wellness trend? The Hard Truth About Hydration Most people think hydration is as simple as drinking enough water. Wrong. If you’ve ever felt exhausted despite drinking litres of water, struggled with brain fog, or suffered from muscle cramps and sluggish recovery after exercise, there’s a good chance you’re missing a key piece of the puzzle: electrolytes. Electrolytes are essential minerals like sodium, potassium, and magnesium that keep your body running smoothly. They: Regulate hydration – Helping your body absorb and retain water effectively. Boost performance – Ensuring muscles contract properly, nerves fire efficiently, and your body keeps up with demands. Reduce muscle cramps – Preventing painful spasms and fatigue caused by mineral depletion. Improve brain function – Supporting cognitive performance, reaction times, and mental clarity. Maintain pH balance – Keeping your body’s internal systems stable for overall well-being. But here’s the problem: when you don’t replenish electrolytes, your body feels it. Dehydration, fatigue, dizziness, and even impaired cognitive function can all stem from electrolyte imbalances. If you’re training hard, sweating, fasting, or simply not eating enough electrolyte-rich foods, you’re losing more minerals than you think. The Science of Electrolytes & Hydration Even mild dehydration affects brain function. Studies show that a 2% drop in hydration can impair memory, focus, and reaction time (Journal of the American College of Nutrition, 2019). Electrolytes prevent muscle cramps. Sodium, potassium, and magnesium imbalances are the biggest culprits behind muscle cramps and post-workout fatigue (Sports Medicine, 2021). Performance drops by up to 20% when you’re dehydrated. A 2020 study found that a 1-2% decrease in hydration levels can lead to a 10-20% decline in endurance and power output (European Journal of Applied Physiology, 2020). Water Alone Won’t Cut It A lot of people assume that staying hydrated is just about drinking more water. But here’s the problem—drinking too much water without electrolytes can actually make things worse. Overhydration (yes, that’s a thing) can dilute sodium levels in your blood, leading to hyponatremia. Symptoms range from headaches and dizziness to nausea, confusion, and in extreme cases, even life-threatening complications. That’s why professional athletes, marathon runners, and high performers don’t just drink plain water—they strategically replenish electrolytes to keep hydration levels balanced. How to Stay Properly Hydrated Want to make sure you’re actually hydrating your body the right way? Here’s how: Drink smarter, not just more. Hydration isn’t just about intake—it’s about absorption. Your body needs minerals to properly retain water. Eat water-rich foods. Cucumbers, watermelon, oranges, and leafy greens naturally contain electrolytes and help with hydration. Replenish electrolytes, especially after sweating. Whether you're working out, fasting, or in hot weather, your body needs sodium, potassium, and magnesium to maintain hydration and muscle function. Ditch sugary sports drinks. Many electrolyte drinks are loaded with sugar, artificial flavours, and unnecessary additives. Your body needs the right balance of minerals—not a sugar spike. Electrolytes & Everyday Life Think electrolytes are only for elite athletes? Think again. They play a vital role in daily life, too. Morning sluggishness? Your body loses electrolytes overnight. A small dose first thing in the morning boosts energy and mental clarity. Post-workout fatigue? Sweat = lost minerals. Replenishing prevents muscle cramps and aids recovery. Fasting or low-carb diets? When you reduce carbs, your body flushes more sodium and potassium—leading to fatigue and dizziness if you don’t replenish. After drinking alcohol? Alcohol is a diuretic, meaning it causes fluid and mineral loss, which is why you wake up dehydrated and groggy after a night out. Proper electrolyte replenishment before bed can help reduce hangovers. The Problem With Most Electrolyte Drinks The issue with many “electrolyte” products on the market? They don’t contain every electrolyte your bodies need or they contain electrolytes in super low concentrations so it’s more of a marketing gimmick than anything else. In addition, many are loaded with sugar and artificial ingredients including silica; an ingredient I despise and will be talking more about on our social channels. Most mainstream electrolyte drinks contain: Excess sugar – Leading to unnecessary calorie intake and blood sugar crashes. Artificial additives – Unnecessary chemicals that do more harm than good. Cheap mineral sources – Making them less effective at restoring balance. Your body deserves better. The Innermost Solution The Hydrate Blend – a science-backed, 100% natural electrolyte formula that’s free from silica, artificial ingredients, and sugar. It hydrates up to 5x more than water alone, making it perfect for everyday hydration and workouts. Unlike most sports drinks, it delivers every single electrolyte in the right balance without sugar or synthetic fillers. Whether you’re an athlete, a busy professional, or just trying to stay sharp and feel great, The Hydrate Blend helps you stay hydrated, recover faster, and perform at your best. Final Thoughts Hydration isn’t just about drinking more water—it’s about absorbing it effectively. If you’re constantly feeling tired, sluggish, or cramping up, chances are your electrolyte balance is off. So next time you feel off, don’t just chug another glass of water—make sure you’re replenishing the right minerals, too. Read more
