Dairy products might be meddling with your dreams.
\n
\nNew research published Tuesday in the journal\u00a0Frontiers in Psychology\u00a0surveyed sleep habits, particularly dreams, and compared them with peoples\u2019 eating habits. One of the findings? The worse lactose intolerance symptoms people had, the more\u00a0intense their nightmares were.<\/p>\n
The study may offer some answers to questions raised by\u00a0research from 2015\u00a0that looked at factors that influence \u201cfood-dependent dreaming\u201d \u2014 in other words, how foods affect dreams.
\n\u201cIn the earlier study, people were blaming cheese all the time for their bad dreams,\u201d said Tore Nielsen, a professor of psychiatry at the University of Montreal who co-authored both studies. \u201cAnd so I think we got some better answers in the study for that.\u201d<\/p>\n
The study included just over 1,000 participants.\u00a0People who responded that they had severe gastrointestinal symptoms from their\u00a0lactose intolerance\u00a0reported stronger nightmares, measured by the frequency of nightmares, the level of distress they caused, how much they impaired daily activities and the duration of the nightmares across months. The participants most commonly blamed their bad dreams on dairy and sweets.
\nThe participants took the survey as part of an undergraduate introductory psychology class. Because of that, the results may not apply to the wider population.<\/p>\n
Still, both the researchers and outside experts said there are plausible explanations for why a cheesy meal before bed could lead to bad dreams.
\nSymptoms of anxiety that might accompany lactose intolerance could be creating more nightmares, Nielsen said.
\nMarie-Pierre St-Onge, the director at the Center of Excellence for Sleep & Circadian Research at Columbia University Irving Medical Center, said the\u00a0sleep disturbances\u00a0caused by gastrointestinal issues may explain the link.
\n\u201cIf you have GI issues, that could account for a lot of what\u2019s happening in terms of your sleep disturbances that could be associated with different dreams,\u201d St-Onge said.
\nPatrick McNamara, an associate professor of neurology at Boston University Chobanian & Avedisian School of Medicine who studies the brain and sleep, said eating a trigger food for lactose intolerance may cause \u201cmicro-arousals\u201d that disturb sleep quality, resulting in stronger nightmares.<\/p>\n
However, both McNamara and the study authors cautioned that other factors unrelated to gastrointestinal symptoms could play a role, as well.
\nNielsen said he wants to see more research done on the link between dairy and dreams. Russell Powell, a co-author of the new study and professor emeritus of psychology at MacEwan University in Alberta, said they plan to try to replicate the findings in other groups.
\nStill, people can look at their own diets and make decisions about aspects to change \u2014 interventions that don\u2019t necessarily need the assistance of a medical professional to do, Nielsen added.<\/p>\n
In conclusion, the study suggests a possible link between lactose intolerance and intense nightmares. While the results are intriguing, more research is needed to fully understand the relationship between dairy consumption and dreams. Individuals who experience frequent nightmares may want to consider their diet and lifestyle habits as a potential contributing factor.<\/p>\n
Q: Can cheese really turn my dreams into nightmares?
\nA: According to the study, people with severe lactose intolerance symptoms reported stronger nightmares, and dairy products were commonly blamed for bad dreams.
\nQ: What are the possible explanations for the link between dairy and nightmares?
\nA: Symptoms of anxiety accompanying lactose intolerance, sleep disturbances caused by gastrointestinal issues, and "micro-arousals" that disturb sleep quality may all contribute to the link.
\nQ: Should I change my diet if I experience frequent nightmares?
\nA: While the study suggests a possible link between dairy consumption and nightmares, more research is needed to fully understand the relationship. However, individuals may want to consider their diet and lifestyle habits as a potential contributing factor.<\/p>\n","protected":false},"excerpt":{"rendered":"
