(Mercola)—A healthy cognitive function is vital for navigating daily life, but it’s something many take for granted until it starts to slip. Alzheimer’s disease is a striking example of what happens when cognitive decline worsens. Characterized by the accumulation of amyloid plaques and tau tangles in the brain, Alzheimer’s disease disrupts neuronal communication and causes brain cell death, leading to impaired memory, language and daily functioning.
Globally, an estimated 47 million people worldwide are living with dementia, with Alzheimer’s disease accounting for 60% to 80% of these cases. This number is expected to surge to over 131 million by 2050 as the global population ages. In the United States alone, the prevalence of Alzheimer’s among those aged 65 and older is projected to rise significantly, with life expectancy after diagnosis typically ranging from three to nine years.1
Alzheimer’s disease (AD) presents significant challenges due to its progressive nature and lack of a cure. Conventional treatments, which include medications, often focus on managing symptoms rather than stopping its progression, but they often come with side effects and have limited efficacy. As a result, there is a growing interest in alternative approaches, such as physical activity, which offers a low-cost and accessible means to combat cognitive decline.
Daily Activity, No Matter How Small, Boosts Brain Speed
A recent study2 from Penn State College of Medicine explored how different types of physical activity affect cognitive processing speed. To conduct this study, the participants were asked to log their physical activities and complete cognitive tests five times a day for a week using a mobile app. This approach allowed researchers to gather dynamic, real-time data, providing a more comprehensive understanding of how daily movements influence cognitive processes.
The results showed that participants experienced improved cognitive processing speed by approximately 60 milliseconds immediately after physical activity. This is equivalent to a reduction in cognitive age by about four years. The improvement was evident in tasks like symbol-matching, which assesses how quickly the brain processes and responds to visual information.3
One of the key mechanisms behind these cognitive benefits is the heightened sense of alertness that accompanies physical activity. Movement increases physiological arousal in the brain, which in turn boosts alertness and cognitive readiness. As a result, you’re better prepared to focus your attention and perform tasks with greater efficiency.
Interestingly, while higher-intensity exercises benefit cognitive health by releasing beneficial chemicals and neurotransmitters that support neuronal function and enhance communication between brain cells, the research confirms that even everyday activities deliver meaningful cognitive advantages.
Physical activity, regardless of intensity, is also linked to improved cardiovascular function, which enhances blood flow to the brain, creating an environment that supports optimal brain performance.
These findings highlight the profound impact that everyday physical activities have on cognitive processing speed. Whether it’s a brisk walk, a household chore or light stretching, engaging in any form of movement leads to significant short-term improvements in brain function. Hence, incorporating regular physical activity into your daily life is a simple yet effective strategy for enhancing your mental performance and maintaining cognitive health.4
Exercise Fuels Your Brain Flexibility and Sharpens Your Memory
The Penn State College of Medicine study aligns with earlier research from 2015, published in Cellular and Molecular Life Sciences,5 which demonstrated how aerobic and resistance exercises enhance cognitive functions and maintain brain health without the use of medications. By examining adult and elderly populations, the study provided comprehensive insights into how different types of physical activity influence the brain.
Participants engaged in aerobic activities, such as running or cycling, and resistance training, like weightlifting. Both types of exercise significantly improved spatial learning and memory, skills essential for navigating environments and recalling locations. Regular physical activity was found to induce structural changes in the hippocampus, a region responsible for memory and navigation.
In both human and animal models, exercise increases the size of the dentate gyrus, where new neurons are generated. Remarkably, in rodents, this area could double or triple in size with consistent activity, directly enhancing memory and learning outcomes.
Another striking finding was the impact of aerobic exercise on visual pattern separation, which helps you distinguish between similar images — a key component of memory retention. Young adults who maintained a routine of aerobic exercise showed superior memory performance compared to less active individuals.
Resistance training provided unique benefits for elderly participants, leading to sustained improvements in spatial memory and other cognitive functions over six months.6
The study also explored biological mechanisms underlying these improvements. One major factor identified was the increase in brain-derived neurotrophic factor (BDNF), a protein that plays an essential role in brain plasticity, enabling the brain to adapt, reorganize and form new connections. Higher BDNF levels were consistently linked to improved memory and cognitive flexibility.
Exercise also boosts insulin-like growth factor 1 (IGF-1), which supports neuron growth and survival, further enhancing learning and memory.7
Synaptic plasticity (how efficiently neurons communicate) was another area of focus. Exercise-induced increases in BDNF and IGF-1 improved synaptic plasticity, creating an environment conducive to efficient information processing and retrieval. Long-term potentiation (LTP), a mechanism essential for memory formation, was also enhanced. In rodent models, running significantly strengthened LTP, highlighting exercise’s role in memory storage and recall.
Moreover, the study emphasized that regular physical activity supports neurogenesis, particularly in the hippocampus. The ongoing generation of new neurons fosters cognitive resilience, helping the brain adapt to age-related decline or neurodegenerative conditions. This continuous renewal process ensures the brain forms new memories and responds effectively to new challenges.8

Two Storms, One Harvest
Every food crisis in living memory has been a one-shock event. The 2008 price spike was a commodity bubble. The 2020 shortages were a logistics failure. The 2022 grain scare was a war on one exporter’s ports. Each time, the system bent, adjusted, and recovered, and each time the experts assured us afterward that global markets are simply too big and too diversified to fail.
What nobody in Washington seems eager to discuss is that 2026 is shaping up to be something the modern food system has never actually faced. Two independent shocks, one climatic and one geopolitical, are converging on the same harvest cycle at the same time. Not sequentially. Simultaneously.
Start with the weather. The Pacific Ocean is currently building toward what forecasters now openly call a record event. NOAA’s Climate Prediction Center puts the odds of at least a strong El Niño near 88 percent, with roughly two in three odds it reaches “very strong” status, the tier reserved for perhaps three or four events in the entire satellite era. Every major global model now projects a median peak in Super El Niño territory, and most of them project it exceeding the 2015-16 event, which until now held the modern record. Sea surface anomalies were already brushing the super threshold in mid-July, months before these events normally peak. The atmosphere has already shifted into El Niño mode, and the event is forecast to crest in late fall and early winter.
This is not about “climate change.” It’s about the standard cycles of weather, and the cycle we’re currently in is one that has likely devastated societies in the past. We’re better prepared as a society today, but not all Americans are equally prepared.
Serious households have started doing the quiet math on their own. Grocery bills tell part of the story, and the forecast maps tell the rest, which is why long-term food storage has moved from fringe hobby to mainstream line item in the family budget, with established suppliers like Heaven’s Harvest seeing demand from people who five years ago would have rolled their eyes at the idea. That instinct is not paranoia. It is pattern recognition, and the pattern is worth walking through carefully.
Editor’s Note: Heaven’s Harvest IS a sponsor, but the warnings of this article are real and would be written even if we didn’t have a survival food sponsor. With that said, those who take advantage of what they offer can use promo code “Patriot” for 15% off.
The Fertilizer Clock Is Already Running
While the Pacific warms, the second shock has been unfolding in the Strait of Hormuz. The conflict with Iran turned the world’s most important energy chokepoint into a contested waterway, and the consequences reach far beyond the gas pump. Roughly a third of global fertilizer trade moves through Hormuz, and the disruption sent urea prices up 86 percent year over year by March, with a 53 percent jump in a single month.
The World Bank projects energy prices rising about 24 percent in 2026 and fertilizer about 31 percent. By its own accounting, fertilizer prices ran 35 percent higher in the first five months of this year than the same period last year.
Here is the mechanism the nightly news will not explain. Fertilizer is not a grocery item. It is a time-delayed input. The nitrogen a farmer in Iowa or Punjab could not afford to apply this spring does not show up as a problem this spring. It shows up as a thinner harvest six to twelve months later.
The World Bank’s own food security brief concedes that the effects of reduced applications earlier this season “are likely to become visible only later in harvest outcomes.” Translate that from institutional language into plain English and it means this. The damage is already done, it is already in the ground, and we are simply waiting for it to arrive on the shelf.
Now check the calendar. Six to twelve months from the spring planting season lands us squarely in late 2026 and early 2027. Which is precisely when the strongest El Niño in the instrumental record is forecast to peak, bringing its signature droughts to Southeast Asia, Australia, southern Africa, northern Brazil, and South Asia, the very regions that grow the world’s rice, sugar, and oilseeds.
The World Bank warns openly that a strong El Niño “could disrupt multiple crop belts simultaneously” on top of the conflict-driven input costs. Their baseline projection assumes the Middle East disruptions ease by autumn. What in the last two years of Middle East history suggests that assumption is safe?
The System Has No Slack Left
The comfortable answer is that global markets always adjust. But adjustment requires slack, and the slack is gone. Global cereal production is expected to decline from last year’s records even before El Niño does its work. The UN World Food Programme, hardly a den of right-wing preppers, is calling this the most significant disruption to its supply chains since Covid and the invasion of Ukraine, and its supply chain director put the stakes bluntly.
Today’s supply chain challenges are tomorrow’s hunger crisis.
There is also a political dimension that markets cannot price. When food gets scarce, governments do not behave like economists. They behave like politicians. Export bans, hoarding mandates, and panic buying at the national level turned the modest rice shortfall of 2008 into a global crisis, and analysts are already warning that import-dependent nations are the first dominoes.
The 2015-16 Super El Niño, a far weaker event than what is now forecast, threw tens of millions into food stress across Africa and Asia. This one is projected to be stronger, and it arrives with fertilizer already rationed by price and shipping lanes already contested by missiles.
What Joseph Knew
Scripture does not treat preparation for lean years as faithlessness. It treats it as wisdom delivered in advance to those willing to act on it.
Behold, there come seven years of great plenty throughout all the land of Egypt: And there shall arise after them seven years of famine; and all the plenty shall be forgotten in the land of Egypt.
Joseph did not respond to that warning with a hashtag or a committee. He stored grain during the years of abundance, and when the famine came, Egypt stood while its neighbors begged. The lesson is not that famine is certain. It is that the time to prepare is precisely when preparation still looks optional.
Nobody who filled a pantry in a year of plenty has ever regretted it, and nobody standing in an empty aisle has ever been glad he waited for certainty.
None of this calls for panic, and panic is the enemy of sound judgment anyway. It calls for the same unglamorous prudence our grandparents considered ordinary. Keep some cash margin, know your local growers, and put real food in deep storage while it is cheap and available, because the entire arc of this story is that cheap and available is a closing window.
Families looking for a straightforward place to start can visit Heaven’s Harvest and use promo code Patriot for 15 percent off long-term storable food. The forecasts may yet soften, the strait may yet reopen, and we should pray they do. But hope is a fine thing to hold and a foolish thing to eat.
