Eating Habits and Insomnia: Exploring the Connection

Insomnia is a condition with causes that vary from person to person and can be a result of stress, caffeine, and excessive screen time. Can modifying eating habits help reduce episodes and improve sleep patterns?

 

Eating Habits and Insomnia

Insomnia is a common sleep disorder characterized by persistent difficulty falling asleep, staying asleep, and/or both. Individuals often experience daytime sleepiness, mood disturbances, or cognitive impairments. There are two types:

• Primary insomnia, which is not linked to other health conditions.
• Secondary insomnia is associated with other health issues like asthma, depression, or heartburn. (National Library of Medicine, 2024)

While there are various causes of insomnia, researchers have recently learned more about its impact on eating habits. New data has found that an individual’s dietary pattern may impact sleep habits. (Gan Z. H. et al., 2024)

Risk Factors

Chronic insomnia is linked to negative health outcomes, including an increased risk of high blood pressure, diabetes, obesity, depression, heart attack, and stroke. (Chalet F. X. et al., 2023) (Marie-Pierre St-Onge et al., 2016) Researchers recruited over five thousand participants who did not have insomnia and evaluated their eating habits and insomnia incidence. (Gan Z. H. et al., 2024) Results showed that 464 of the participants developed insomnia, and of those, the risk was lower in vegetarians than those who ate more meat. Males who followed a more plant-based diet had a reduced incidence of insomnia; however, this relationship was not seen among females. The research suggests that a diet with more vegetables may positively affect sleep. Many plant-based foods are rich sources of sleep-supporting compounds, such as melatonin. Treating and preventing insomnia is important for restoring health and daily functioning.

Past nutritional data highlights the relationship between healthy sleep and a diet rich in fruits, vegetables, legumes, and other sources of tryptophan and melatonin. (Zuraikat F. M. et al., 2021) Prior research also shows how vegetarian diets can help reduce chronic inflammation, positively impacting sleep. (Dzierzewski J. M. et al., 2020) Specifically, the Mediterranean diet, known for its anti-inflammatory effects, is linked to improved sleep and reduced insomnia. (Zaidalkilani A. T. et al., 2021) Also, data links a vegetarian diet to improved mood, which might enhance the quality of sleep by moderating mental health, including depression condition. (Wang X. et al., 2023)

Support Quality Sleep

According to dieticians, looking at an individual’s eating habits during the day is crucial in determining why they can’t sleep at night. Often, making a few small dietary adjustments is enough to help with better sleep. Some steps to try include:

• Increase magnesium by adding more leafy greens, nuts, and seeds.
• Incorporating melatonin-rich foods like walnuts rather than relying on melatonin supplements.
• Easing off caffeine, alcohol, and refined carbohydrates can help improve sleep quality.

Dietary changes should not be the only way to combat insomnia. Cognitive behavioral therapy (CBT-I) is a recommended first-line treatment rather than sleeping medications, along with learning healthy sleep habits and using the right mattress. This therapy can help improve sleep habits and behaviors by rethinking sleep and current practices that could affect an individual’s ability to sleep well. Combining CBT-I with a healthy diet and regular physical activity can significantly impact overall health and sleep patterns.
