Every human being is born with two hippocampi, located on each side of their head. An essential part of the limbic system, it is essential for memory formation, learning, memory and spatial navigation. Now, new research has claimed that physical movement, even for 10 minutes, can significantly boost the efficiency of this part of the brain. This could, in turn, mitigate the risk of Dementia and other neurodegenerative diseases.

In a compelling interview with Big Think, Dr. Wendy Suzuki, Dean of the College of Arts and Sciences at New York University and Professor of Neuroscience and Psychology, argued that even minimal physical activity can have a profound impact on cognitive functions and emotional well-being.

Dr. Suzuki's fascination with the hippocampus—a critical brain structure involved in forming and retaining long-term memories—was sparked by the case of Henry Molaison. He underwent an experimental surgery to alleviate severe epilepsy, resulting in the removal of both hippocampi. While the procedure reduced his epileptic symptoms, it left him unable to form new memories, highlighting the hippocampus's essential role in memory formation.

Regular Physical Activity Stimulates Growth Of Hippocampus

Building on this foundation, Dr. Suzuki's research reveals that regular physical activity stimulates the growth of new brain cells, particularly in the hippocampus, thereby enhancing memory and increasing its volume. She emphasises that one doesn't need to engage in intense workouts to reap these benefits; even a 10-minute walk can trigger a "neurochemical bubble bath," releasing neurotransmitters like dopamine, serotonin, and endorphins that boost mood and mental clarity.

Beyond memory enhancement, exercise has been shown to improve focus and emotional resilience. Dr. Suzuki notes that consistent physical activity can lead to long-term brain health, making it a powerful, yet often overlooked, tool for cognitive improvement.

In addition to her work on exercise and the brain, Dr. Suzuki explores the interplay between anxiety and neuroplasticity. She explains that while anxiety is a natural response, our modern lifestyles can exacerbate it. However, practices like meditation and regular physical activity can recalibrate neural pathways associated with anxiety, leading to improved stress responses and overall mental health.

Dr. Suzuki's insights underscore the importance of integrating physical movement into our daily routines. Whether it's a brief walk or a structured exercise regimen, moving our bodies can lead to significant improvements in brain function and emotional well-being. Her research serves as a compelling reminder that taking care of our physical health is intrinsically linked to our cognitive and emotional health.

Climate change has become a big concern for people all around the world. We are observing temperatures rising every year, and the effect of global warming. Things like the heat affecting the ice caps, living conditions of people as well as the flora and fauna in various places. However, this climate change may also be the reason for increasing diseases among people. Passive effects of the climate change may be something we all deal with, but the increase in temperatures could also be a reason for increase in diseases like cancer in women.

A recent study published in the Frontiers in Public Health journal suggested that as the world gets hotter due to climate change, women may face a greater risk of certain cancers. This research looked at countries in the Middle East and North Africa where rising temperatures have been linked to more cases and deaths from cancers affecting women, like breast, ovarian, and uterine cancers.

What is The Link Between Heat and Cancer?

The study found a clear pattern, whenever the temperature rose, there was an increase in both new cancer cases and deaths among women. This means that as temperatures climb, more women are getting and dying from these specific cancers, especially ovarian and breast cancers.

Even small increases in temperature can have a big impact on public health over time. What's happening in these already hot countries could be a warning sign for other places, like those with cooler climates now, about what might come.

Researchers examined cancer data from 17 countries in the Middle East and North Africa over two decades. These countries are already experiencing significant temperature increases because of climate change.

The study showed that women are more sensitive to health risks related to climate, especially during pregnancy. The findings highlight a strong connection between rising heat and an increase in cancer cases and deaths among women.

Specifically, for every extra degree Celsius, there were an estimated 173 to 280 more cancer cases per 100,000 women. Ovarian cancers saw the biggest increase in cases, while breast cancers had the smallest. Similarly, cancer deaths rose by 171 to 332 per 100,000 women for each degree of temperature rise, with ovarian cancer deaths increasing the most and cervical cancer deaths the least.

Six countries were particularly affected by these increases - Qatar, Bahrain, Jordan, Saudi Arabia, the United Arab Emirates, and Syria.

How Does High Temperature Increase Risk of Cancer?

While higher temperatures are likely a direct risk factor, the heat might also worsen other things that cause cancer, like air pollution. Scientists believe that rising temperatures can work in several ways to increase cancer risk. This includes increasing exposure to known cancer-causing substances, making it harder to get healthcare, and possibly even changing how cells in the body behave. All these factors together could raise the risk of cancer over time.

It's important to understand that this study shows a connection, but it doesn't directly prove that climate change causes these cancers. More research is needed to fully understand how higher temperatures might affect cancer risk.

In the meantime, experts say that public health officials should start considering climate-related risks in their plans. This means improving cancer screening programs, creating healthcare systems that can handle climate challenges, and reducing exposure to things in the environment that cause cancer. If we don't address these underlying vulnerabilities, the number of cancer cases linked to climate change will likely keep growing.

The India Meteorological Department (IMD) has warned that many regions across the country will experience above-normal temperatures and a rise in the number of heatwave days this May. According to IMD Director General Mrutyunjay Mohapatra, the number of heatwave days is expected to increase by one to four days across most parts of Rajasthan, Haryana, Punjab, Madhya Pradesh, Uttar Pradesh, Bihar, Jharkhand, and Gangetic West Bengal.

Heatwaves are extended periods of abnormally high temperatures, which can range from a few days to several weeks or even months. They pose significant health, social, environmental, and economic challenges. With the rising threat of heat waves, it is crucial to understand the various health issues triggered by extreme heat conditions.

Heat Stroke

Heat stroke is the most serious heat-related illness. It occurs when the body’s natural temperature regulation fails, pushing the core body temperature above 104°F (40°C). The condition can develop suddenly and become life-threatening if not treated promptly. Heat stroke requires emergency medical attention.

Heat Exhaustion

Though milder than heat stroke, heat exhaustion remains a serious concern. It results from the excessive loss of water and salt through sweating, especially during physical activity in high temperatures. People working outdoors or engaging in exercise during the peak heat hours are particularly vulnerable.

Dehydration

In extreme heat, the body loses fluids more rapidly through sweat. If these fluids are not replenished, dehydration can occur. Symptoms include fatigue, headache, dry mouth, decreased urine output, and dizziness. Severe dehydration may impair organ function and poses a significant risk to vulnerable groups such as the elderly, children, and those with chronic medical conditions.

Heat Cramps

Heat cramps are painful, and involuntary muscle spasms are caused by electrolyte imbalances and fluid loss due to intense sweating. These cramps often affect the muscles of the abdomen, arms, or legs and are common among people performing strenuous physical activities in hot environments.

Sunburn

Prolonged exposure to sunlight can lead to sunburn, which is an inflammatory reaction of the skin to ultraviolet (UV) radiation. While mild sunburn may cause redness and discomfort, severe cases can result in blistering, peeling, infections, and long-term damage, including an increased risk of skin cancer.

With much of India bracing for hotter-than-usual weather, health experts urge people to take precautions: stay hydrated, avoid peak sun hours, wear protective clothing, and seek immediate medical attention if symptoms of heat-related illnesses arise.

Late-night hustle culture may still be glorified in some corners of the tech world, but not everyone is buying into it—especially not billionaire entrepreneur and longevity advocate Bryan Johnson. The 46-year-old tech mogul, known for his extreme anti-ageing lifestyle, recently called out an Indian software engineer who boasted on social media about working until 4 a.m. "It's 4 AM, guys, but builders are building. What’s your excuse?” the programmer posted on X (formerly Twitter), celebrating his grind.

Johnson, however, wasn't impressed. "It may feel heroic," he replied, “but you’re spending down your human capacity.” He went on to explain the physiological cost of burning the midnight oil: a 30% reduction in brain oxygen, suppression of melatonin due to blue light, disrupted deep sleep, and impaired insulin sensitivity the next day. “The missed sleep raises cortisol, increases visceral fat, and decays memory,” Johnson added. His critique struck a nerve, triggering a wave of agreement from other users on the platform.

"No good code is being written at 4 a.m. and ruining your morning focus—the best focus of the day,” one commenter noted. Another wrote, “Whatever they are building now by staying awake will be built by an AI agent in 10 minutes, five years from now. What’s the point?" A third user summed it up bluntly: “The excuse is to feel good, rest, be healthy, and make better decisions.”

Man Behind The Mission

Johnson is not your average tech mogul. Best known for founding Braintree (later acquired by PayPal) and Kernel, a company developing brain-machine interfaces, he has poured millions into an audacious personal experiment: to slow, and possibly reverse, ageing.

Through what he calls Project Blueprint, Johnson adheres to a meticulous regimen involving diet, exercise, and sleep optimisation. He follows strict health protocols, including unconventional methods like plasma transfusions from his teenage son—a procedure that has sparked both fascination and ethical debate.

In a recent post on X, Johnson shared his detailed morning routine, which begins at 4:30 a.m. and lasts until 10 a.m. His day starts with monitoring his inner ear temperature, applying a custom "BP hair serum," and donning a red light cap. He then exposes himself to 10,000 lux of light to reset his circadian rhythm.

Breakfast is a carefully curated "Longevity Mix" consisting of protein, collagen, extra virgin olive oil, and antioxidant-rich berries, followed by a personalised supplement stack. His morning workout includes strength training, flexibility drills, balance exercises, and either Zone 2 cardio or high-intensity intervals. Johnson’s message is clear: productivity shouldn’t come at the cost of long-term health. In his eyes, sacrificing sleep to meet deadlines is not a badge of honour—it’s a sign of unsustainable living. As more voices from the tech community question the glorification of burnout culture, Johnson’s warning serves as a timely reminder: no innovation is worth your health.
