One of the many beliefs that people hold, especially the older generation, is that the new way of living, which is highly protected and sanitized, has made kids weaker. While there are certain evolutionary changes we have developed over the past few centuries, it is arguable whether we are . However, their theory may not be far from the truth, but how do we know that? To this day, there are certain communities who enjoy a quiet living, void of modern possessions like the Amish community.
Surveys have noted that Amish children tend to have lesser allergies or asthma cases, but how?
Scientists have long known that kids who grow up on traditional farms are less likely to have asthma and allergies. This is called the "farm effect," and it seems to be caused by being around farm animals, especially cows, and the microbes (tiny living things) that are found there.
In a 2018 study, researchers from The University of Manchester and Northern Care Alliance NHS Foundation Trust studied two unique farming communities in the U.S.: the Amish and the Hutterites. Both groups have similar genes and lifestyles, but they farm in very different ways, and this seems to be the reason for their different health outcomes.
Another 2020 study done by the American College of Allergy Asthma & Immunology compared the living of Amish and Old Order Mennonite, who also have a similar style of living, with a few comparable changes.
The Amish and Hutterites both came from the same group in Europe and have similar lifestyles. They eat similar foods, have large families, and avoid many modern habits like having indoor pets or using the internet. However, their farming practices are completely different.
The Amish use old-fashioned, family-run farms with horses for work. Their barns are close to their homes, so children are around the animals and barn dust from a young age.
The Hutterites live on large, modern, industrial farms. Their barns are big and located far from their homes, so children have little contact with the animals or barn environment.
This difference in lifestyle led to a major difference in health. The study found that Amish children have a very low rate of asthma (just 5.2%), while Hutterite children have a much higher rate (21.3%). This shows that the environment, not their genes, is the most important factor in preventing asthma.
The 2020 study researchers created a survey to compare the health of these two groups. They asked families about different types of allergies they had, as well as their lifestyle and farming practices.
They found that families in both groups lived on farms and drank raw, unprocessed milk. However, the Amish families had more children on average and lived on smaller farms with fewer animals compared to the Mennonite families. The survey results showed a significant difference in health between the two groups:
The Amish families reported having a much lower rate of allergies overall. Only about 26% of Amish households had a family member with an allergy.
The Mennonite families had a much higher rate of allergies, with nearly 47% of households reporting an allergy.
One key difference is that while both the Amish and Mennonites have large families, Mennonite communities sometimes use modern technology like tractors and electricity. In contrast, the Amish stick to traditional, old-fashioned farming.
This difference in farming methods could change the types of microbes (tiny living things) found in the farm environment. Since other research has shown that these specific microbes are important for preventing allergies, the different farming practices might explain why the Amish have a much lower allergy rate.
The scientists found a key difference in the homes of the two groups: Amish homes had much more endotoxin, a type of dust from bacteria. When this dust was tested on mice, the dust from Amish homes protected the mice from developing asthma. However, dust from Hutterite homes actually made the mice's asthma worse.
This suggests that the kind of dust and microbes you are exposed to matters. The dust in Amish homes is full of "good" microbes that help a child’s immune system grow and develop correctly, preventing it from overreacting and causing asthma.
The study also looked at the children's blood and immune systems. They found that the Amish children’s immune systems were very different from the Hutterite children's. The Amish kids had a stronger innate immune system, which is the body's first defense against germs. Their immune cells were "calm" and seemed to be trained to not overreact to things that can trigger asthma.
This research strongly suggests that the farm effect works by "training" the immune system. Early exposure to a wide variety of microbes helps the body learn how to respond correctly, which in turn protects against asthma.
While these studies give us a lot of great information, there are still many questions to answer. Scientists still need to figure out exactly which microbes or substances in the farm environment are the most protective. They also need to study children at a younger age to see how their immune systems change over time.
But for now, the findings from this research confirm that growing up on a traditional farm and being exposed to its rich environment is a powerful way to protect against asthma and allergies.

We live in a world that treats sleep like a competitive sport. Everyone has got a hack: tape your mouth shut, stretch your nostrils wider, eat two kiwis before bed. But according to experts, the real secret is not exotic fruit or gadgets; it is light, or rather, the absence of it.
Scroll through wellness feeds and you will find people swearing by everything from magnesium powders to bedtime meditation playlists. Some tricks have merit; others are straight out of the pseudoscience playbook. But amid the noise, one factor keeps coming up: how much light your body gets and when.
Let us start with night. Darkness is not just cosy; it is medicine. When the lights go out, your brain flips into melatonin-making mode. That is the hormone that whispers, “Hey, it is time to crash.” But throw in a glowing phone screen or a streetlamp sneaking past your curtains, and suddenly your brain thinks it is noon in July.
The fix is to go all dark with blackout curtains, eye masks, and unplugged chargers. The darker your sleep space, the deeper and less interrupted your rest will be.
The irony? The same thing that wrecks your sleep at night is exactly what you need when you wake up. Sunlight is like nature’s alarm clock, telling your body to get moving, boosting your energy, and resetting your circadian rhythm so you do not feel like a zombie.
Experts say the trick is to step into daylight as soon as possible, before checking your phone, brewing coffee, or turning on the TV.
Of course, there is a modern nemesis in this story: blue light. Your phone, laptop, and TV blast out wavelengths that convince your brain it is still daytime. This results in no melatonin, no drowsiness, and no sleep.
The cure is not complicated; shut the screens at least an hour before bed. If you cannot, at least switch to night mode or throw on a pair of blue-light glasses. Better yet, trade doomscrolling for something less… glowy.
At the end of the day, you do not need kiwis or space-age gadgets. The best sleep formula is old-school:
Sure, studies suggest nutrients like magnesium might help you snooze, but the clearest evidence points to light as the MVP of sleep health. Darkness at night, sunlight in the morning – it is free, it is effective, and it is a lot less weird than mouth taping.

Living past 100 does not require magic potions or futuristic science; Dr John Scharffenberg proves it with simple daily habits. At 101, this Harvard-trained physician is still actively sharing what he calls the very simple, very human secrets to longevity. His approach is not about chasing immortality but about maintaining a body and mind that allow you to enjoy your years—whether you are at 30, 60, or, in his case, well past a century.
Dr Scharffenberg insists exercise is not just a nice-to-have; it is non-negotiable. He puts it bluntly: a woman who is overweight but exercises daily will outlive a lean woman who avoids movement. That is how powerful regular activity is.
What is more, he stresses that midlife is the most crucial time to stay active. Consistent exercise during those years does not just help with weight; it may reduce the risk of Alzheimer’s and slow down other age-related declines.
Even at 101, the doctor has not hung up his walking shoes. While he no longer pushes himself through intense workouts, he makes sure to walk daily, recommending seniors aim for at least two miles a day. Walking, he says, builds muscle strength, maintains independence, and could even add hours to your lifespan for every hour you put in.
As a Seventh-Day Adventist living in Loma Linda, California—one of the world’s rare “blue zones” where centenarians thrive—Dr Scharffenberg follows a largely vegetarian diet. And it is not a trend. Research shows Adventists live longer than the average American, with vegetarians among them adding up to two extra years on average.
The Adventist kitchen is built around five food groups that Scharffenberg swears by:
He also has a soft spot for mangoes, praising them not just for their taste but also for their brain-boosting vitamin B6 and antioxidants that protect eyesight and may even reduce cancer risks.
One of Dr Scharffenberg’s biggest concerns is how many people, even those who think they eat well, are quietly deficient in crucial vitamins. He points out three that are often lacking, especially in older adults:
Dr Scharffenberg has seen health fads come and go, some with more harm than good. His philosophy is almost shockingly ordinary: eat mostly plants, stay active, avoid smoking and alcohol, and keep an eye on vitamins that silently decline with age. He believes these basics do not just add years to your life but add life to your years, keeping both body and brain in shape.
In his words, you do not need miracle cures. You need to walk, to eat beans and greens, and to give your body the nutrients it quietly depends on. It’s the steady choices, repeated daily, that build the foundation of longevity.
As people look for high-tech hacks to outsmart ageing, Dr Scharffenberg embodies a simpler truth: living long and well is not about beating biology; it is about working with it. His century-long experiment in health proves that small, consistent habits can outpace even the best modern medicine.

Cannabis-induced psychosis is becoming increasingly common across the UK. With stronger strains easily available and a perception that weed is harmless, doctors are seeing worrying consequences for mental health.
Psychosis is not just a medical term; it describes a mental state where someone loses touch with reality. A person in a psychotic episode may hear voices, see things that are not there, or believe unusual ideas with unshakeable certainty. Everyday surroundings feel warped, thoughts become jumbled, and behaviour can change dramatically. These episodes can last days, weeks, or longer, and while many people recover, some continue to experience symptoms for years.
Psychosis is not a condition in itself but a symptom of underlying mental illnesses such as schizophrenia, bipolar disorder, or drug-induced disorders. And cannabis, once dismissed as a “soft” recreational drug, is increasingly proving to be a serious trigger.
The UK has no shortage of cannabis users. In the year to March 2024, about 2.3 million people reportedly admitted to using the drug. But while regular use has halved over the past two decades, psychiatrists are alarmed by a sharp rise in cannabis-induced psychosis cases. The problem is potent modern strains and the growing popularity of “skunk”.
Skunk is produced from unpollinated cannabis plants with naturally higher levels of THC, the psychoactive compound responsible for the drug’s “high”. Unlike traditional varieties, these turbocharged versions can push the brain into paranoia, hallucinations, and even long-term mental health conditions.
According to reports, the public health problem is deepening. There has been a visible rise in the number of people needing intensive support for psychosis as a result of cannabis use. What begins with smoking a few ‘joints’ and feeling a bit paranoid can easily escalate.
The issue is compounded by the fact that cannabis is readily available online. High-strength weed can be bought and delivered with the same ease as ordering a takeaway. For some users, that ease leads them into dangerous territory. Over time, repeated exposure to potent cannabis does not just spark temporary paranoia; it can cement itself into a chronic psychotic state.
For those caught in its grip, cannabis-induced psychosis can be terrifying. Hallucinations distort familiar environments, creating confusion and fear. Dissociation leaves people feeling detached from their own bodies or surroundings. Everyday interactions can feel hostile or threatening, and the person’s sense of what is real becomes fragile.
While these symptoms may fade once the drug wears off, for some they linger, leading to severe depression or even suicidal thoughts. Studies suggest cannabis can also trigger schizophrenia in vulnerable individuals, an illness characterised by recurring psychotic episodes, delusions, and long-term disability.
You might wonder, why is today’s cannabis so much more risky? The answer lies in THC levels. Traditional cannabis varieties contained lower amounts of this psychoactive compound, and many also carried cannabidiol (CBD), a chemical thought to counteract some of THC’s mind-altering effects. Skunk, however, has been bred to maximise THC and reduce CBD.
This results in a product that is stronger, more destabilising, and far more likely to provoke psychosis. While occasional users may brush it off as a “bad trip”, for others, the effects can be life-altering.
Despite the popular image of cannabis as a “chill” substance, psychiatrists are dealing with an entirely different reality. Hospitals and rehab centres across the UK are seeing more young people admitted with psychosis linked to cannabis. Over time, people can reach a psychotic state which would not go away, even if they stop smoking. They can become very depressed or suicidal.
The public health implications are significant. Not only do psychotic disorders put immense strain on the NHS, but they also derail lives, disrupting work, education, and relationships.
The narrative around cannabis has long been tangled. To some, it is a natural plant, a stress reliever, even a medicine. But the reality is more complicated. Yes, cannabis contains compounds with therapeutic potential, but when engineered for potency and consumed regularly, it can become a gateway to enduring mental illness.
People need to know that today’s cannabis is not the same mellow joint their parents smoked in the 1970s. It is stronger, riskier, and capable of tipping vulnerable minds into frightening psychological territory.
