Snacking on cheese late at night may haunt your dreams, Canadian study finds
A new Canadian study has found that a late-night cheese snack could lead to nightmares. The study, published in psychology journal Frontiers on June 30, looked at the link between food, sleep quality and dreams. It revealed that just over 40 per cent of participants said eating certain foods affected their sleep, with nearly a quarter saying some foods worsened sleep. A small group of participants, 5.5 per cent of them, said food even affected their dreams. The culprit for both pleasant and disturbing dreams? Dairy. It was most frequently identified as the food category with the most influence. When it came to nightmares, researchers found that a contributing factor was lactose intolerance. That could explain why munching on cheese before catching some Zs led to bizarre, disturbing dreams for some. According to the study, it's possible that gastrointestinal (GI) symptoms increase nightmares by 'increasing symptoms of anxiety and depression,' which can also impact sleep quality. As well as dairy, other types of foods linked to nightmares were sweets, meat and spicy foods. The belief that food can affect dreams goes back centuries, based on old tales and anecdotal evidence, the study explained. One such example, cited in the study, is a cartoon by artist Winsor McCay, showing a character that blames eating cheese before bed for bizarre dreams and nightmares. We certainly weren't expecting to see the relationship to nightmares to be so robust Tore Nielsen 'Although we had predicted that lactose intolerance might be related to dreaming… we were a bit skeptical and we certainly weren't expecting to see the relationship to nightmares to be so robust,' the study's lead author Dr. Tore Nielsen told National Post over email on Wednesday. Nielsen said, in a Frontiers news release, that it makes sense for lactose intolerant people who suffer from GI symptoms and disrupted sleep to have worse nightmares 'because we know that other bodily sensations can affect dreaming.' 'Nightmares can be very disruptive,' he said, 'especially if they occur often, because they tend to awaken people from sleep in a dysphoric state. They might also produce sleep avoidance behaviours. Both symptoms can rob you of restful sleep.' Nielsen, a University of Montreal psychiatry professor and director of the Dreams and Nightmares Laboratory, told National Post that researchers also didn't expect to see a link between food allergies and nightmares. Participants with food allergies and gluten Intolerance were more likely to report that food affects dreaming, while those with lactose intolerance were more likely to report that food causes worse sleep, per the study. Those with food allergies may be 'more sensitive and attuned to what they eat,' the authors wrote, making them more likely to attribute dream changes to diet. Meanwhile, having pleasant dreams was linked to eating fruits and vegetables and drinking herbal tea, as well as desserts and dairy. Researchers linked an unhealthy diet, in general, to nightmares. 'An unhealthy diet included eating in the evening before bed and not paying attention to internal cues about being hungry or full in deciding when or how much to eat,' Nielsen told National Post. 'It is possible that people with nightmares could find some relief not only by checking on their lactose intolerance and food allergy status and dosing their intake of the problematic foods accordingly, but by following a healthier diet.' Although the study's authors said that they still 'lack substantive evidence that these participant observations for food and dreaming are, in fact, accurate, there is some suggestive evidence for their accuracy.' The study's findings show how diet could inform interventions for sleep disturbances that don't rely on medication. Although the latest findings uncovered some answers, there is still a need for more research, including studies to find out if people can truly detect the effects of specific foods on dreams, Nielsen said in a Frontiers news release. There were 1,082 participants in the study, who were all undergraduate students at MacEwan University. The data was collected online from January to April 2023. The study's authors noted that those who took part could have been biased due to having academic exposure to related topics that influenced how they interpreted or reported the perceived effects of food on sleep and dreaming. One study published in 2022 in the International Journal of Dream Research observed whether or not substances and foods had any effects on dreams and lucid dreams (the person is aware they are dreaming). It found that eating fruits correlated to dream recall, while eating fish correlated with the frequency of lucid dreams. However, it determined that research on the topic is 'scarce' and more testing is needed. In 2005, the British Cheese Board said that different kinds of cheese can influence dreams based on the group's own research. In an interview with NPR, the board's secretary Nigel White said that although some people had 'wacky' dreams, none of the volunteers who took part in the survey had nightmares. As well as Nielsen, researchers from the University of British Columbia in Vancouver and Grant MacEwan University in Edmonton co-authored the study.

Cheese May Actually Fuel Nightmares, Surprising Study Confirms
Weird dreams and vivid nightmares following late-night consumption of cheese products are surprisingly common complaints, but scientific evidence linking the two has been lacking. A new study investigating the relationships between food, sleep, and dreams confirms a number of foods you eat before bed may indeed have a very real impact on the night ahead. Dream neuroscientist Tore Nielsen of the University of Montreal, who led the study, is often asked whether food affects dreaming, and has published research on the topic before. In the new study, he and his team recruited 1,082 psychology students from Canadian MacEwan University to undertake an online survey that probed their food habits, sleep time and quality, dreams, and nightmares. It also assessed their perception of how certain kinds of food, and time of eating, impacted their sleep and dreams, if at all. Related: "These new findings imply that changing eating habits for people with some food sensitivities could alleviate nightmares. They could also explain why people so often blame dairy for bad dreams," says Nielsen. Only 5.5 percent of respondents believed the type of food being eaten and the timing of its consumption before sleep affected their dreams, but most people in this group blamed either dairy or sweet foods for changes. This was especially true of disturbing or bizarre dreams: 31 percent blamed these on desserts or sweets, while 22 percent blamed dairy. The researchers also found a strong association between lactose intolerances and food allergies and nightmares and poor sleep, perhaps because gas and stomach pains interrupted sleep in ways that increased the chances of experiencing and recalling dreams. This suggests that treating food intolerances and allergies with dietary changes may improve people's sleep, as well as their gastrointestinal comfort. "Nightmares are worse for lactose-intolerant people who suffer severe gastrointestinal symptoms and whose sleep is disrupted," says Nielsen. "This makes sense, because we know that other bodily sensations can affect dreaming. Nightmares can be very disruptive, especially if they occur often, because they tend to awaken people from sleep in a dysphoric state. They might also produce sleep avoidance behaviors. Both symptoms can rob you of restful sleep." The study also found that people who eat healthier (better food, more intuitive eating, and less food in the evening) report better dream recall, while people who ate less healthily (more junk food, less reliance on hunger and satiety, eating more food in the evening) tended to have more severe nightmares, or dreams with a more negative tone, and (perhaps thankfully) lower dream recall. Because the study is based on self-reported data from university students, it's not necessarily representative of the broader population. And it can only tell us about people's perception of the relationship between food and dreams, not the actual mechanisms that could cause such a phenomenon. "We need to study more people of different ages, from different walks of life, and with different dietary habits to determine if our results are truly generalizable to the larger population," Nielsen says. "Experimental studies are also needed to determine if people can truly detect the effects of specific foods on dreams. We would like to run a study in which we ask people to ingest cheese products versus some control food before sleep to see if this alters their sleep or dreams." We're sure it won't be difficult to find volunteers. The research was published in Frontiers in Psychology.

Waking from weird nightmares? You might need to cut this from your diet
Don't miss out on the headlines from Lifestyle. Followed categories will be added to My News. The theories about food's impact on our sleep are never-ending, but new research suggests this snack could be fueling your nightmares. If you're constantly waking up surprised by how bizarre your nightmares are, shocking your friends with perfectly dramatised voicenotes of your night running through a hellscape, or have been told more than once that your subconscious' nighttime escapades could make for a great blockbuster movie, you may want to look at your diet. Researchers in Canada have done a deep dive on the causes of weird dreams, and sadly, one of our favourite snacks is listed as a possible culprit. You may need to leave the cheese in the fridge before bed if you want to sleep soundly. X SUBSCRIBER ONLY How does cheese impact your dreams? 1082 people participated in the study to try to assess how food affects people's dreams. While you'd be hard pressed to find them as listed symptoms of food intolerances, the article tied worse perceived sleep to lactose intolerance. Studies and wivestales have linked cheese to poor sleep before, with the researchers referencing a 20th-century cartoon series where characters blamed their bizarre dreams on 'having eaten Welsh rarebit — a spicy melted cheese toast — or other cheese dishes prior to sleep.'' In a previous study, the team had seen people 'blaming cheese all the time for their bad dreams'. Image: Pexels In a previous study, the team had seen people 'blaming cheese all the time for their bad dreams', but co-author Tore Nielsen told NBC News, 'I think we got some better answers in the study for that.' 21 per cent of participants reported changes to their dreams after eating dairy, and 22 per cent said their dreams were more disturbing after consuming the milk-based products. And after measuring the frequency, level of distress and impact on daily life of their nightmares, the team determined that those who had severe gastrointestinal symptoms from lactose intolerance had more intense nightmares. According to the study, food allergies and gluten intolerance could also play a part in our bad dreams. Image: iStock Nielsen suggested that the anxiety that comes with symptoms could contribute to the frequency of nightmares, while associate professor of neurology at Boston University Chobanian and Avedisian School of Medicine, Patrick McNamara said people with lactose intolerance who eat triggering foods could have their sleep disturbed by 'micro-arousals', which could contribute to worse nightmares. Other foods that could bring on bad dreams It's not just cheese, milk and ice cream triggering your most insane, hard-to-follow nightmares either. According to the study, food allergies and gluten intolerance could also play a part in our bad dreams. Dairy, gluten and sweets were linked to nightmares. Image: iStock More than a quarter of participants noted that eating desserts or sweets triggered dreams and a worse night's sleep too. The research team concluded that ''the frequency of dream recall was associated with indicators of healthy eating, i.e., higher scores on a subscale of the Intuitive Eating Scale-2 and less frequent eating in the evening'. 'While both negative emotional tone of dreams and (measured) nightmare severity… were associated with unhealthy indicators, i.e., combinations of Lactose Intolerance, GI symptoms, less reliance on hunger and satiety cues, and a tendency to eat in the evening.'

Can consuming cheese trigger bad dreams?
Woke up sweaty because of a bad dream? Maybe it's the cheddar cheese pizza that you had for dinner that is keeping you and bad dreams have been the centre of debate for a long time. Even Ebenezer Scrooge from A Christmas Carol blamed his 'crumbs of cheese' and his food for the ghost he saw. Now, a recent peer-reviewed study claims that there can be a link between nightmares and out, cheese and crackers might be racking up more than calories; they could be stealing your sleep!The study says... What we eat does not only affect the waistline or growth, it can affect our sleep patterns too. There are studies where participants have perceived a relationship between food and a study published in Frontiers Psychology, over 1000 participants were surveyed for the concept of food-dependent dreaming. Around 40.2 per cent reported that certain foods affected their sleep. About 31 per cent blamed desserts or sweets, while 22 per cent held dairy as the when it comes to dairy, cheese takes the spotlight owing to all the folklore it has driven in the past. Cheese may affect sleep (Photo: Unsplash) advertisementWhat's interesting is that most people who reported bad dreams due to dairy products were also lactose intolerant.'Nightmare severity is robustly associated with lactose intolerance and other food allergies,' said Dr Tore Nielsen, Universite de Montreal, lead author of the article in Frontiers in Psychology, in a statement. "These new findings imply that changing eating habits for people with some food sensitivities could alleviate nightmares. They could also explain why people so often blame dairy for bad dreams!'Say cheese or not?In agreement with Dr. Nielsen's statement, Dr. Pushkar Arvind Shikarkhane, Internal Medicine, Lilavati Hospital, Mumbai, explains India Today how cheese can affect sleep and dreams."Some cheeses, especially aged and fermented varieties like cheddar, blue cheese, and camembert, contain higher levels of tyramine. Tyramine is an amino acid that can stimulate the brain and adrenal glands, potentially leading to a "fight or flight" response. While most people can process tyramine without issues, in sensitive individuals or those on certain medications, it can potentially interfere with sleep and may lead to nightmares."Experts believe that certain kinds of cheese may affect the body more due to its tyramine content, which makes it hard to fall asleep. Mild cheese like mozzarella and cottage cheese are generally considered less likely to cause sleep if your midnight snack is a slab of stinky blue cheese, don't be surprised if your dreams get equally it's not just cheeseDo you remember the episode from Disney's show Hannah Montana where Miley Cyrus experiences bad dreams after sipping a piping cup of hot chocolate right before bed? Well, cheese might not be the only in desserts may disrupt your sleep cycle because of a blood sugar spike. "Eating sugary or fatty foods at night, like sweets, desserts, or ice cream, can mess with your blood sugar and digestion. This may lead to poor-quality sleep, more awakenings during the night, and sometimes restless or bad dreams," says Dr. Rahul Agrawal, HOD and clinical director of internal medicine, dietician, diabetologist, CARE Hospitals, food is not the only villain. Lifestyle and health issues can trigger it as well. "Nightmares are not caused only by food. They can happen due to Obstructive Sleep Apnea (OSA) also. The most common symptom of OSA is snoring," cautions Dr for thoughtBefore you toss every candy bar, there's more to the story. Experts say that moderation and time are key. Here are some expert-backed tips for a good night's sleep and to avoid nightmares:advertisementAvoid heavy meals, cheese, sweets, and desserts at least two - three hours before light snacks like a small banana or nuts if you are drink tea, coffee, or chocolate in the a two-three-hour gap between dinner and bedtime. Going to bed by 11 pm is ideal as per should consume balanced meals inclusive of protein, veggies, and whole grains, to keep sugar hydrated throughout the day, but don't drink too much water right before research on food-dependent dreams and their impact on the sleep cycle is still limited, it's gradually growing. The study's author also notes the need to expand this research across diverse age groups, backgrounds, and habits to better understand and generalise the findings for a broader population.- Ends

Urgent 'nightmare' warning issued to anyone that eats cheese
A study claims that fans of cheese should be warned about the potential side effects and impact. A study of over 1,000 people found that those with lactose intolerance reported overall worse quality sleep and significantly more bad dreams Can say with 100% certainty that cheese before bed does not give me nightmares. They said dairy may cause 'gastrointestinal disturbance' that can disrupt sleep. Study author Dr Tore Nielsen, from the University of Montreal, in Canada, said: 'Nightmares are worse for lactose-intolerant people who suffer severe gastrointestinal symptoms and whose sleep is disrupted. 'This makes sense because we know that other bodily sensations can affect dreaming. These findings imply that changing eating habits for people with food sensitivities could alleviate nightmares. 'They could also explain why people so often blame dairy for bad dreams. We're routinely asked whether food affects dreaming. Now we have some answers.' Experts reckon digesting dairy can cause gut pain that plays havoc with the sleeping brain. Speaking previously, Dr Dennis Schmoltzi, CEO at Emma Sleep, said: 'Whether scientifically proven or just an old wives' tale, there's no doubt that Brits have identified a link between their cheese intake, and the strange visions that feature in their dreams. Recommended reading: 'Unfortunately for those who believe they have had a cheese-induced night-fright, 'tis the season to be cheesy – and vivid dreams may be part and parcel with Christmas celebrations. 'The admiration and love for cheese felt by Brits is clear to see – and with Christmas on the horizon, I have no doubt that households across the country are dusting off their cheese boards. 'It is interesting to note the number of cheese-lovers who feel snoozy after indulging in their favourite snack – a relationship which might account for a portion of the unscheduled festive naps taken this Christmas.'
