New Study Links Cheese Consumption to Increased Nightmares in Sleep

A recent study published in the journal *Frontiers in Psychology* has unveiled a surprising correlation between cheese consumption and the occurrence of nightmares, particularly among individuals who are lactose intolerant. The research, conducted by a team at MacEwan University in Alberta, Canada, surveyed over 1,000 psychology students to explore how dietary choices may influence dream content and sleep quality.

The study's findings suggest that while only 5.5% of respondents reported a direct influence of food on their dreams, dairy products emerged as a significant factor in the dreams of participants. Researchers noted that lactose-intolerant individuals who consumed dairy before bedtime experienced increased instances of nightmares and unusual dream narratives. Dr. Tore Nielsen, the lead researcher from Université de Montréal, attributed these disturbances to gastrointestinal discomfort caused by lactose intolerance, which can disrupt sleep patterns.

"Nightmares are worse in lactose-intolerant individuals who experience severe gastrointestinal symptoms and whose sleep is disrupted," stated Dr. Nielsen in an official press release dated July 6, 2025. The study highlights that symptoms such as bloating, heartburn, and indigestion can interfere with restful sleep, leading to a heightened likelihood of disturbing dreams.

Moreover, nearly 40% of participants acknowledged that food influenced their overall sleep quality, with desserts, spicy foods, and dairy identified as the primary culprits. The correlation between poor dietary habits and increased nightmares was also evident, as healthier eating patterns and avoidance of late-night snacks were associated with improved dream recall and more restful sleep.

This research aligns with previous studies indicating the intricate relationship between diet and sleep health. For instance, a 2019 study published in the *Journal of Clinical Sleep Medicine* found that late-night eating can exacerbate sleep disorders, emphasizing the importance of mindful eating for improved sleep quality.

Experts in the field have echoed these findings. Dr. Sarah Johnson, a Professor of Nutrition at Harvard University, noted, "Understanding how specific foods impact sleep can be crucial for those struggling with sleep-related issues. This study adds to the growing body of evidence that diet plays a significant role in sleep health."

In light of these findings, health professionals may advise individuals, particularly those with lactose intolerance, to reconsider their nighttime snacking habits. Alternatives such as bananas, almonds, or chamomile tea can provide a pleasant pre-sleep snack without the adverse effects associated with dairy.

As sleep quality remains a critical component of overall health, further research is warranted to explore the broader implications of diet on sleep and dream states. This study not only sheds light on the specific impact of cheese but also opens the door for future investigations into how various foods may influence our nightly experiences. The implications of these findings reach beyond individual dietary choices, indicating a need for increased awareness of how food can affect mental health and well-being during the sleep cycle.
