Man reveals the horrifying - and potentially deadly - impact of going 264 hours without sleeping
A man who stayed awake for a shocking 264 hours has detailed the horrifying toll it took on his body and mind.
In 1963, 17-year-old Randy Gardner made a pact to stay up for a record length of time with two friends, in a bid to win first prize at their local annual greater San Diego science fair.
The teenagers were aiming to go 260 hours, or just under 11 days, without sleep in order to break the world record—as well as discover what the experiment would do to the human brain.
But within just a few days, the endeavour began to yield some concerning results.
Now, one of the teens involved in the schoolboy experiment has revealed what really happened during the record-breaking stunt, deemed so dangerous that the Guinness World Records will no longer monitor it.
'For years and years I've just hibernated,' admitted Mr Gardner, now 67, in a video posted to the Guinness World Records YouTube account. 'I don't know why I agreed to talk.'
Shortly after Christmas in 1963, Mr Gardner recruited Bruce McAllister, and Joe Marciano Jr. to help keep him awake.
After flipping a coin, it was decided that Mr Gardner would be the guinea pig.
Following 72 hours of no sleep, Mr Gardner experienced concentration issues and short-term memory loss, as well as bouts of moodiness, paranoia and hallucinations.
'About the forth or fifth day, I was like-are you kidding me, this is hard,' Mr Gardner said.
'By then it had gotten out to the newspapers and the wire services picked it up and it was too late, I couldn't back out.
'So there I was, stuck in this thing. So I thought, let's do it, let's do the 11 days.'
In the meantime, a sleep researcher at Stanford University, William Dement, had read about the experiment in the news, and decided to join the boys for the last three days.
Later dubbed Dr Sleep and named the father of sleep science, Dr Dement studied Mr Gardner's physical and mental wellbeing, keeping close records of his state.
He drove the sleep-deprived 17-year-old around in a convertible, with the radio on full-blast, and challenged him to games of pinball.
Miraculously, Mr Gardner actually managed to win the match-despite at that point having gone ten days without rest.
'We did everything. We walked the beaches at all hours. We visited the county jail at three in the morning,' Mr Gardner said. 'You name it, we did it.'
His only stimulants during the challenge were Coca Cola, loud music and hot and cold showers.
His classmates Mr McCallister and Mr Marciano also administered a set of 20 tests every six hours, to assess his mental state.
By the end of the experiment, Mr Gardner was experiencing memory loss, slurred speech and hallucinations.
He was also having trouble with his coordination.
But the teen prevailed—finally surpassing the 260 hours of sleeplessness previously claimed in 1959 by Honolulu DJ Tom Rounds.
Mr Gardner had been awake for 11 days and 25 minutes.
Afterwards, he slept for 14 hours and 45 minutes at the Naval Hospital in San Diego, under observation by Dr Dement and his team, who monitored his brain waves, heartrate, temperature, muscle activity and blood pressure.
But despite the stunning length of time spent without sleep, the teen was deemed fine—quickly returning to a normal sleep schedule.
The record was since broken multiple times until 1997, when Guinness World Records stopped accepting new attempts for safety reasons.
At that point, it was held by Robert McDonald, who spent 18 days and 21 hours (453 hours and 40 minutes) awake.
Years since the experiment, Mr Gardner has reported suffering from decades of unbearable insomnia—which he blames on his long bout without sleep as a teen.
Poor sleep has been linked to a number of health problems, including cancer, stroke and infertility.
Experts have long advised that waking up during the night does not necessarily mean you have insomnia, which figures suggest affects up to 14million Brits.
Still, sleep deprivation takes its own toll, from irritability and reduced focus in the short term, to an increased risk of obesity, heart disease and diabetes.
According to the American Sleep Association, nearly 70 million Americans also have a sleep disorder.

Deadly fungus that 'eats you from the inside out' invades US: 'Hundreds of thousands of lives at risk'
A lethal fungus that can rot human tissue from within is spreading rapidly across the US, and experts warn the problem could worsen as temperatures rise. Aspergillus fumigatus is airborne and nearly impossible to avoid. Its spores are so tiny that people inhale them without noticing. It can cause a serious lung infection called aspergillosis, which in vulnerable individuals can lead to organ failure and death. Those with weakened immune systems, such as patients with cancer, asthma, or HIV, are especially at risk. Scientists have found the fungus invading parts of the US, with Florida, Louisiana, Texas, Georgia, and California seeing the highest exposure due to hot, humid climates and farming activity. Major cities like New York, Houston, and Los Angeles face added risks from dense populations and aging infrastructure. Officials said that aspergillosis isn't a reportable disease in the US, meaning infections, hospitalizations, and deaths aren't tracked, making it hard to detect. Doctors advise people with weakened immune systems to avoid soil, gardening, and moldy environments, wear masks in dusty areas, and maintain clean air in hospitals and homes. US hospitals have stepped up mold inspections and antifungal protocols. Co-author Norman van Rhijn, from the University of Manchester, told the Financial Times: 'We're talking about hundreds of thousands of lives, and continental shifts in species distributions. 'In 50 years, where things grow and what you get infected by is going to be completely different.' About 400,000 of these cases develop into chronic pulmonary aspergillosis, a long-term lung infection. Invasive aspergillosis is less common but far deadlier. It mainly targets people with weakened immune systems and can spread from the lungs to the brain, heart, and kidneys. One study found only 59 percent of organ transplant patients survived a year after infection, and just 25 percent of stem cell transplant patients. Hospitalizations for invasive aspergillosis in the US rose about three percent annually from 2000 to 2013. By 2014, nearly 15,000 hospital stays were recorded, costing an estimated $1.2 billion. ICU autopsies show aspergillosis ranks among the top four infections likely to cause death. The World Health Organization lists Aspergillus fumigatus as a 'critical priority' fungal threat due to rising drug resistance and high death rates. The fungus thrives in warm, damp environments, even surviving temperatures above 120 degrees Fahrenheit in compost piles. Climate change is making it easier for the fungus to survive inside the human body as global temperatures rise. A new study conducted by University of Manchester found that if fossil fuel use continues at current levels, the fungus could expand by more than 75 percent by 2100, putting millions more at risk in the southern US, where conditions mirror those forecasts. Azole drugs, widely used to treat fungal infections in humans, are also heavily applied in agriculture to protect crops. Experts warn this overuse may be driving drug resistance, which can transfer from the environment to humans and reduce treatment effectiveness. A study published in the Applied and Environmental Microbiology, found azole-resistant, Aspergillus fumigatus in farm soil across at least seven US states, with many strains resistant to standard antifungal drugs. Scientists warn the mixing of different fungal types is speeding resistance spread and suggests the problem is already deeply rooted in US soil. The WHO urges immediate investment in safer drugs, faster testing, and better training for health workers, while calling on drug companies to prioritize fungal research and include children in clinical trials. 'This isn't science fiction,' said Dr Vyas, an infectious disease expert at Columbia University. 'These infections are real, and we're not ready.'

Gen X and millennials three times more likely to be diagnosed with appendix cancer than their parents, study finds
Cases of appendix cancer appear to be rising among Gen X and millennials, according to a new study that found those age groups are three times more likely to face a diagnosis than their parents. The research, published in Annals of Internal Medicine earlier this month, found that the diagnosis of the rare disease is sharply rising among people in those generations. Cancer of the appendix, the small pouch-like organ attached to the large intestine that supports the immune system, affects 1 or 2 people for every million people in the U.S., according to the research. Compared to those born between 1941 to 1949, incidence rates of appendix cancer have more than tripled among people born between 1976 and 1984 and more than quadrupled among people born between 1981 and 1989, according to the new report. 'It's alarming overall,' Dr. Andreana Holowatyj, the lead study author and an assistant professor of hematology and oncology at Vanderbilt University Medical Center and Vanderbilt-Ingram Cancer Center told CNN. 'We're seeing some of these generational effects for cancers of the colon, the rectum, the stomach, and so that's one of the reasons why we were curious to explore this in rare appendix cancers. But nonetheless, the rates and trends which we observed were alarming and worrisome,' she said. Researchers conducting the study looked at data from 4,858 people in the U.S. who were 20 or older and had been diagnosed with appendix cancer between 1975 and 2019. The data was separated into five-year age groups and showed rising rates of appendix cancer by group, especially among those born after 1945. The study did not clarify why cases of appendix cancer are on the rise, though researchers said it is 'unlikely' to b down to advances in screening and diagnostic methods. Instead, they speculate it may be tied to environmental exposures, such as obesity. Those exposures may increase the risk for generations now entering mid-adulthood, the researchers wrote, noting similar trends 'have also been reported for colon, rectal, and gastric cancer.' 'The fact that we're seeing these trends parallel across other cancers of the gastrointestinal tract does tell us, or suggest, that there may be both shared and distinct risk factors that can contribute to cancer development across younger generations in the gastrointestinal tract,' Holowatyj said. There is currently no screening recommendations for appendix cancer, but symptoms of the disease are similar to appendicitis and include abdominal or pelvic pain, bloating, nausea and vomiting. Appendix cancer may be treated with surgery, in which the appendix is removed. If the cancer has spread, patients are often given chemotherapy. 'This is a disease where, if not caught before the appendix ruptures, tumor cells disperse throughout the abdominal cavity often,' Holowatyj said. 'That's why up to 1 in every 2 patients are diagnosed with metastatic disease' or cancer that has spread.

Be aware of the hidden dangers of your guilty pleasures that could cause cancer, including being busy
A sip of wine, a craving for pizza, having a full calendar may all seem like harmless aspects of life but a scientist has revealed such seemingly innocent actions could be putting you on the brink of developing cancer. University of California's Dr Raphael Cuomo claims chronic stress, fast food, alcohol, and drugs are an almost surefire way to set yourself up for a diagnosis with the disease later in life. In Dr Cuomo's new book Crave: The Hidden Biology Of Addiction And Cancer, he noted that the body's repetitive desire to indulge in junk food and addictive behaviors drove the body to the deadly condition: 'Crave reveals how modern habits like vaping, binge-eating, and daily cannabis use hijack our biology.' The expert added: 'These behaviors quietly damage the body's ability to repair itself. Over time, they open the door to cancer. It is not about genetics or bad luck. It is about the choices we make every day.' Over 600,000 Americans and more than 150,000 Brits die of various cancers every year. After studying 'millions of patient records' from across the University of California hospitals and spending months reviewing studies on cancer biology, Dr Cuomo revealed what he says are the top habits most likely to cause the destructive illness. Fast food Dr Cuomo called eating fast food 'slow poison', and noted that its effects could not be seen immediately but might cause long-term damage. Earlier this year, researchers tested more than 300 foods sold at restaurant chains and in grocery stores across America for two microscopic toxins that have been linked to cancer, infertility, and autism. They found that of all fast-food restaurants, the salad chain Sweetgreen and coffeehouse Starbucks scored poorest. Sweetgreen's Chicken Pesto Parm Salad and Starbucks' Matcha Latte was found to contain the highest amount of phthalates, a group of chemicals used to make plastics more flexible and transparent. Studies showed that phthalates, commonly used in food packaging material, imitate the body's hormones and interfere with the production of and response to natural hormones like estrogen and testosterone. Some phthalates were linked to certain cancers, particularly breast cancer and lymphoma. However, Dr Cuomo pointed towards fiber consumption as a critical part of reversing damage as it would help improve gut bacteria, reduce inflammation, and keep cells healthy. Smoking and drinking Smoking causes about 30 per cent of overall cancer deaths in the U.S. and is a leading cause of lung, brain, neck, and bladder cancer. Alcohol consumption's been linked to an increased risk of several types of cancer, including breast, colon, liver, and esophageal cancer. About 20,000 people die of booze-related cancers, annually. Researchers in Germany found that a combination of drinking and smoking significantly raised the risk of colon cancer in young Americans. Researchers analyzed two dozen studies, comparing regular drinkers and smokers with people who abstained from both. Just 100 cigarettes in a person's lifetime - the equivalent of one per week for two years - was linked to a 59 per cent higher risk of colon cancer compared to people who never smoked. They also found drinking alcohol every day raised the risk of developing early onset colon cancer by 39 per cent, even if it's just one or two drinks per day. Alcohol and smoking have both been linked to cancer in the past, as they release chemicals that destroy DNA and cause cells to mutate. Also, each daily can of beer or glass of wine further increased the chance by an additional two per cent. In his book, Dr Cuomo noted that deep sleep is the 'most underestimated tool' to improve damage caused by addictions, such as smoking and drinking. He explained that during consistent deep sleep, the body performs critical tasks such as repairing tissues, regulating hormones, consolidating memory, and clearing metabolic waste. Stress A 2024 study presented at the United European Gastroenterology congress by a group of Chinese researchers noted that a combination of chronic stress and anxiety has been linked to colorectal cancer in young people. They explained when a body is under frequent stress, a number of healthy bacteria that live in the gut start dying off, making it easier for cancer to move in. When the bacteria die off, tumors grow more quickly, leading to more aggressive, rapidly growing colorectal cancers. Research from Trinity College in Ireland suggested these bacteria support the body's immune system, can protect against virus and bacteria, and prevent damage in gut cells. Apart from this, chronic stress can lead to increased levels of cortisol and other stress hormones in the body that can promote cancer growth and its spread to various parts of the body. A constant state of stress can also weaken the immune system's ability to effectively fight off cancer cells. However, Dr Cuomo believes that there are ways to break free from all addictions and prevent cancer development in the body. He said: 'The real threat is not a single cocktail or slice of cake. It is the craving that drives you back again and again. 'That craving is what wears down your body's defenses. I tell people to test their control. Start with one week of abstention. Not forever. Just seven days. That short reset reveals a lot. 'You learn what your body depends on. During that time, focus on physical recovery. Sleep deeply. Move your body. Eat real food. 'Spend time with people you trust. Addiction thrives in isolation. Recovery begins with reconnection.' Additionally, Dr Cuomo suggested replacing the habit by engaging in some form of movement, such as taking regular walks.
