Though we often view the body and mind as separate entities, emerging research reveals they are more connected than we realize. Studies continue to uncover that the brain holds a remarkable ability to influence the body’s functions. These 10 examples highlight how the mind/body connection can either benefit or harm us, depending on our understanding of a situation and our capacity to control our thoughts.
10. Drying Clothes with the Power of the Mind
Tibetan Monks are often admired for their ability to meditate for extended periods, go without food for days, and maintain silence. However, what’s truly remarkable is that some of them can control physiological functions like blood pressure and body temperature—accomplishments that many doctors find astonishing.
In one of the most remarkable demonstrations of their abilities, a group of Tibetan monks allowed doctors to observe the changes in their bodies while performing a meditative yoga practice called g Tum-mo. During this procedure, the monks were wrapped in cold, wet sheets (49°F / 9.4°C) and placed in a room at 40°F (4.5°C). Under such harsh conditions, an ordinary person would likely shiver uncontrollably and soon develop hypothermia. However, through intense focus, the monks were able to generate heat, and within moments, researchers saw steam rising from the sheets. Within an hour, the sheets were completely dry.
Although the demonstration was awe-inspiring to the physicians, for the monks, it was a routine feat. In fact, novice monks often use g Tum-mo to showcase their meditative prowess and even hold competitions to see who can dry the most sheets in a single night.
Buddhists believe the heat they produce is a natural result of meditation, as it takes energy to enter an alternate state of consciousness—a state that is untouched by the realities of the everyday world.
9. Dissociative Identity Disorder
Multiple Personality Disorder, or Dissociative Identity Disorder, is a psychological condition that holds fascination for many reasons. Perhaps the most captivating aspect is how some individuals not only show changes in personality and behavior as they shift between their various identities but also experience measurable physiological differences with each persona. For example, one identity may require eyeglasses, while another does not. Or, one persona could be diabetic, while another enjoys perfect health. In such instances, it’s not just a matter of the patients believing they need glasses or insulin; their bodies undergo actual changes, such as variations in intraocular pressure or blood sugar levels.
In a case reported by the American Psychiatric Press, a physician observed how medications prescribed to a patient with Dissociative Identity Disorder had different effects depending on which personality took the drug. For instance, when a tranquilizer was administered to the patient’s childlike persona, it made the individual drowsy and relaxed. However, when the adult identity took the same drug, it caused anxiety and confusion. Similar results were found in other patients with different medications. Doctors also noted that visible traits, like a lazy eye, would appear or disappear depending on which personality was in control.
This phenomenon is especially intriguing because neither the patients nor anyone else claims that mysticism is involved. On the contrary, it offers a genuine example of how the mind can influence the body.
8. The Placebo Effect
A placebo is an inactive substance or belief that induces genuine biological effects in humans. It’s such a well-established phenomenon that most medical trials include a placebo variable to determine if a drug’s effects are due to its actual properties or simply because people 'believe' it works.
There are countless experiments that demonstrate the placebo effect. However, one of the most entertaining was conducted by a group of Princeton students who decided to throw a non-alcoholic keg party for their unsuspecting peers. The students secretly filled a keg with O'Douls (which contains around 0.4% alcohol, compared to the typical 5% in regular beer) and observed their classmates behave as though they were intoxicated—slurring words, stumbling around, and even sleeping on the ground. Despite the near impossibility of becoming drunk on O'Douls, the belief that they were drinking normal beer altered their actions.
Interestingly, researchers have found that the placebo effect is becoming stronger. Some drugs that have been available for years, like Prozac, are now proving less effective than placebos. This is a significant concern for major pharmaceutical companies, many of which are scrambling to conduct neurological research to protect their industry from the influence of ordinary sugar pills. For reference, Big Pharma is currently more profitable than Big Oil, which means a lot is at stake.
7. The Nocebo Effect
Placebos are typically linked to positive outcomes, such as curing illnesses or enjoying a good time after consuming O’Douls, while the nocebo effect leads to negative consequences. This might include a cancer patient feeling nauseous before chemotherapy or someone developing a rash after mistakenly believing they touched poison ivy, even when the plant was harmless.
A well-known example of the nocebo effect appeared in an article in 'New Scientist.' It told the story of a man named Vance from Alabama who encountered a witch doctor one night in a cemetery. The witch doctor ominously told Vance that he would die soon. Consumed by this belief, Vance rapidly grew ill and wasted away in a matter of weeks. Despite extensive hospital tests revealing no physical cause, Vance’s wife shared the story with Dr. Doherty. This prompted Dr. Doherty to concoct a solution: he claimed to have found the witch doctor and forcibly extracted a lizard from Vance’s body, which, according to the doctor, had been eating him from the inside out. The lizard was merely a planted prop, but the dramatic intervention led to Vance making a miraculous recovery the following day.
This strange tale was corroborated by four medical professionals and is frequently used as an example of why practices like Voo Doo sometimes work—not due to mystical powers, but due to the powerful influence of the nocebo effect.
6. Dreams Have the Power to Cause Real Harm
There are numerous accounts from people who claim to have sustained injuries in their dreams, only to wake up and find physical evidence of the injuries on their bodies. For example, some have dreamt of being burned in a fire and then discovered actual burn marks on their skin upon waking. Others report being attacked during their dreams and then finding scratches on their bodies. However, most of these stories appear in online forums or message boards, making it difficult to verify their authenticity.
However, there is one well-documented case, reported by renowned psychiatrist Ian Stevenson, involving an Indian man named Durga Jatav. During his battle with typhoid fever, Jatav experienced an extraordinarily vivid dream in which he was imprisoned in another realm. His captors cut off his legs to prevent him from escaping. Unfortunately, the captors realized too late that they had the wrong man and no longer needed to keep Jatav. When Jatav asked how he could leave without legs, they offered him a selection of pairs, and after choosing, his legs were miraculously reattached.
While Jatav was experiencing this dream, his body became extremely cold, leading his family to believe he had passed away. A few days later, he revived. Upon waking, his sister and neighbor noticed deep fissures around his knees, which had not been there before. X-rays showed no abnormalities beneath the skin, leading Jatav and his family to believe the marks were a result of his dream. In 1979, Dr. Stevenson visited Jatav and took photos of the scars, which were still visible after 30 years. While Stevenson did not witness the event himself, he accepted the story, which was corroborated by those involved, and included it in his book 'Reincarnation and Biology: A Contribution to the Etiology of Birthmarks and Birth Defects.'
While there is no scientific evidence to support this intriguing story, it is not entirely implausible, considering what we know about the brain's remarkable influence on the body.
5. Yogis Achieve Near-Complete Heartbeat Suspension
Much like the Tibetan monks, Indian Yogis seem to possess an extraordinary ability to control their bodily functions during deep meditation. In 1936, after hearing stories of yogis surviving underground for 28 days, French cardiologist Therese Brosse traveled to India to investigate the validity of these claims. In her experiments, the yogis reportedly slowed their heart rates to such an extent that it could only be detected through an EKG machine.
In the 1950s, Brosse’s research was further expanded by a team of researchers who traveled across India, equipped with an eight-channel electroencephalograph and various other devices. They used these tools to measure the yogis’ brain activity, respiration, skin temperature, blood-volume fluctuations, and skin conductivity. Two of their subjects were placed in airtight sealed boxes on two separate occasions, where they were monitored for 8 to 10 hours. During this period, the yogis exhibited biological traits similar to those seen during sleep. They were able to slow down their heart rate and breathing to such low levels that the concentrations of oxygen and carbon dioxide inside the box remained virtually unchanged from the proportions found in the air at sea level. This demonstrated that by controlling their bodily processes and avoiding panic, the yogis could endure live burial far longer than most people, possibly for weeks.
4. Imagery & Visualization
Many athletes assert that visualization techniques help them perform better by mentally “playing” the game before stepping onto the field or court. While this may seem like just a mental exercise to improve focus, it’s possible that more substantial changes are occurring within the body.
For instance, Air Force Colonel George Hall spent seven years confined to a small, dark North Vietnamese prison. While most would likely lose their sanity under such conditions, Hall mentally escaped by visualizing playing golf every day throughout his imprisonment. His mental imagery was vivid and detailed, from hitting the ball off the tee to raking the sand traps, feeling the wind, and, of course, tapping the ball into the hole.
Despite being weakened and 100 pounds lighter than before his capture, one of the first things Hall wanted to do upon his release was play a real round of golf. He was invited to participate in the Greater New Orleans Open, where he astoundingly shot a 76. When a reporter suggested his performance was merely beginners’ luck, Hall responded, “Luck, I never 3-putted a green in the last five years!”
Despite his physical decline and not having stepped onto a golf course in over seven years, his body had developed muscle memory purely through his vivid visualizations.
3. Boosts Weight Loss
It seems contradictory that, while more people are claiming to put extra effort into exercising and eating healthier, the global obesity rate continues to rise. Some researchers suggest that a lack of positivity is a key missing factor in the weight-loss equation, and this absence could be what’s keeping people from shedding pounds.
To demonstrate the powerful effect the mind can have on the body, Harvard psychologist Ellen Langer conducted an experiment with a group of predominantly overweight hotel maids who, based on their daily activity levels, should have been thin. Even though they were essentially exercising all day through their work, Langer discovered that 67% of the maids felt they weren’t exercising at all. Langer hypothesized that the maids’ beliefs were hindering their weight loss, so she explained to half of the group that their cleaning tasks were actually equivalent to meeting the Surgeon General’s definition of an active lifestyle, in addition to taking their physical measurements. The other half of the maids received no such explanation.
A month later, Langer’s team revisited the hotel and reassessed the maids. The group that had received the information showed a noticeable reduction in systolic blood pressure, weight, and waist-to-hip ratio. The other group showed no significant physical changes. Although some might suggest that merely talking about exercise influenced the women’s behavior, Langer asserted there was no evidence that the maids had altered their routines. She believes the results were due to a shift in mindset alone.
2. Positivity and Meditation
It can be extremely challenging to maintain a positive outlook when battling a life-threatening illness. However, based on numerous medical studies, adopting a positive mindset might be the key to surviving rather than succumbing to the disease.
For instance, in 1989, Dr. David Spiegel from Stanford University conducted a study with 86 women diagnosed with late-stage breast cancer. Half of the women received only standard medical care, while the other half participated in weekly support sessions in addition to their treatment. These sessions provided an opportunity for the women to express their emotions, connect with other patients, and find a positive outlet for coping with their illness. By the end of the study, the women who attended the support sessions lived twice as long as those who didn’t. A similar study in 1999 revealed that cancer patients who felt helpless and hopeless had a significantly lower chance of survival.
David Seidler, the writer of “The King’s Speech,” claimed to have cured his cancer through meditation and visualization. After years of battling bladder cancer, with only two weeks left before surgery, Seidler decided to try using his imagination to heal himself. Though he initially considered it a far-fetched idea, he felt he had nothing to lose. He spent the next two weeks envisioning a clean, healthy, cream-colored bladder. When Seidler went in for his pre-surgery biopsy, the doctor was shocked to find no trace of cancer. The biopsy was sent to four different labs for testing, but the result was the same. While Seidler believes his visualization was responsible for the cancer’s disappearance, the doctor referred to it as a “spontaneous remission.”
1. Block Out Pain
Jack Schwarz, a Dutch Jewish writer, endured unimaginable suffering while imprisoned in a Nazi concentration camp during World War II. Like countless others, he was subjected to severe beatings, starvation, and torture that most people cannot fathom. To cope with this horrific reality, he turned to meditation and prayer, eventually refining his practice to the point where he could mentally block out the pain of his torment, allowing him to endure his dire circumstances.
After his release, Schwarz continued to master the power of his mind over his body, occasionally demonstrating his extraordinary abilities by pushing a long sailmaker’s needle through his arm without harm. He also exhibited his skill in controlling his body's blood flow, manipulating the wound on his arm to bleed or stop bleeding at will. Researchers from the Menninger Foundation studied Schwarz and confirmed his ability to control numerous bodily functions using only his mind. Additionally, an electroencephalograph revealed that his brain exhibited electrical activity unlike that of most other subjects. Schwarz also possessed the ability to see auras, enabling him to sense the physical, emotional, spiritual, and mental states of others.
