Yes, Eating Cheese Gives You Nightmares, Research Finds

A recent study published in Frontiers in Psychology found that people with lactose intolerance were more likely to experience nightmares, especially when they consumed dairy, like cheese, late in the day. The study looked at over 1,000 college students and revealed a pattern of worse sleep and more nightmares among those with food sensitivities, particularly to dairy. Women were more likely to report sleep issues and food intolerances than men, with dairy, sweets, and spicy foods being common triggers for disturbed sleep and bizarre dreams.

The study suggested that dairy, high in fat and protein, could lead to disrupted sleep and nightmares, especially for lactose intolerant individuals. Plant-based cheese options were recommended as a better alternative for those who experience sleep disturbances after consuming dairy. Keeping a sleep and food journal to track any patterns between diet and dreaming was also suggested for those who suspect that food may be influencing their sleep quality and dream content.
