Sleep is a vital component of our overall health and well-being. It is during sleep that our bodies and minds rejuvenate, enabling us to tackle the day ahead with energy and focus.
However, many people struggle to get quality rest, often unknowingly sabotaging their sleep with certain foods and drinks.If you’re aiming for better sleep hygiene and improved energy levels during the day, it’s essential to pay attention to your diet, especially in the hours leading up to bedtime.
Below, we delve into six foods and beverages that can significantly disrupt your sleep.
Caffeine

Caffeine is renowned for its ability to keep us awake and alert, making it one of the most common culprits of poor sleep. Found in coffee, tea, chocolate, energy drinks, and even certain medications, caffeine is a stimulant that interferes with the sleep cycle.
How Caffeine Affects Sleep
When consumed, caffeine blocks adenosine receptors in the brain, which promote sleep. This leads to heightened alertness and can delay sleep onset. Even consuming caffeine up to six hours before bed can delay sleep and decrease sleep quality, leading to a restless night.
Studies have shown that caffeine, even in small amounts, can reduce total sleep time and alter sleep stages, particularly REM sleep, which is crucial for memory consolidation and mental restoration. Individuals sensitive to caffeine may experience more pronounced effects, which is why it’s recommended to limit caffeine intake in the afternoon and evening.
Alternatives
If you’re craving a late-night drink, opt for herbal teas like chamomile or valerian root tea. These natural options promote relaxation and may help prepare your body for sleep.
Spicy Foods
While spicy foods can add flavor to a meal, they can also make it harder for you to fall and stay asleep. Hot peppers, chili, and other spicy foods can trigger indigestion and exacerbate symptoms of acid reflux and heartburn.
The Impact of Spicy Foods on Sleep
When you eat spicy foods, capsaicin, the compound responsible for the heat, increases your body’s core temperature. This spike in temperature can make it more challenging for your body to cool down and enter the deeper stages of sleep.
Additionally, spicy foods can cause discomfort in the digestive system, which becomes more pronounced when you lie down. The reflux of stomach acid into the esophagus can cause a burning sensation in the chest, disrupting your ability to rest.
Alternatives
To avoid digestive discomfort, opt for lighter meals and avoid rich, spicy dishes close to bedtime. Choose easily digestible foods such as lean proteins, leafy greens, and complex carbohydrates.
High Glycemic Foods
Foods with a high glycemic index (GI), such as white bread, pasta, sugary cereals, and pastries, can cause rapid spikes in blood sugar levels. While this might give you a quick burst of energy, it can disrupt your sleep later.
The Link Between High Glycemic Foods and Sleep
High-GI foods trigger an insulin response, which causes a sharp rise and fall in blood sugar levels. This fluctuation can lead to feelings of anxiety, hunger, and irritability, making it harder to relax and fall asleep. Studies have also shown that diets rich in refined carbohydrates and added sugars are associated with an increased risk of insomnia.
Additionally, the blood sugar drop that follows the initial spike can lead to wakefulness during the night, disrupting the sleep cycle.
Alternatives
Switch to low-glycemic foods, such as whole grains, legumes, and non-starchy vegetables. These foods provide a steady source of energy and help ensure a more restful night’s sleep.
Fatty Foods

High-fat foods, particularly those rich in saturated fats, have been shown to negatively impact sleep quality. While fat is an essential nutrient, excessive consumption of fried foods, fatty meats, and dairy products can disrupt sleep.
How Fatty Foods Interfere with Sleep
Fatty meals take longer to digest, which can lead to discomfort, bloating, and indigestion, especially when consumed close to bedtime. Furthermore, high-fat diets have been linked to less restorative sleep, as they interfere with the body’s natural ability to enter deep, restorative sleep stages, including REM.
In particular, diets high in trans fats and saturated fats have been associated with an increased risk of sleep disorders, such as insomnia.
Alternatives
Choose healthy fats like those found in avocados, nuts, and olive oil. These fats are not only beneficial for overall health but are also easier on the digestive system when consumed in moderation.
Ultra-Processed Foods
Ultra-processed foods, including fast food, packaged snacks, and sugary beverages, can significantly impact your sleep patterns. These foods are often high in refined carbohydrates, unhealthy fats, and added sugars, all of which can disrupt sleep.
Why Ultra-Processed Foods Affect Sleep
The high levels of added sugars and fats in ultra-processed foods can cause blood sugar imbalances and inflammation, both of which can interfere with the sleep cycle. Additionally, the artificial additives and preservatives found in processed foods may directly affect the nervous system, contributing to sleep disturbances.
Studies have also shown that a diet rich in ultra-processed foods is associated with poorer sleep quality and shorter sleep duration, particularly among adolescents and young adults.
Alternatives
Opt for whole, unprocessed foods such as fresh fruits, vegetables, and lean proteins. These foods provide essential nutrients that support better sleep without the added risks associated with processed foods.
Alcohol

Many people turn to alcohol as a way to unwind and promote sleep, but while it may help you fall asleep faster, it can ultimately lead to poor-quality rest.
The Effect of Alcohol on Sleep
Alcohol initially acts as a sedative, making it easier to fall asleep. However, as the body metabolizes alcohol, it causes sleep disruptions. Alcohol suppresses REM sleep, the most restorative phase of the sleep cycle, and often leads to wakefulness during the night. As blood alcohol levels drop, your body experiences withdrawal, which can lead to restlessness, anxiety, and frequent waking.
Alternatives
If you enjoy a drink in the evening, try limiting your intake and avoiding drinking right before bed. Herbal teas or warm milk may offer a soothing alternative without affecting your sleep.
Conclusion
Achieving restful sleep requires more than just a good bedtime routine—it also involves making mindful choices about the foods and drinks you consume, particularly in the hours leading up to sleep. By avoiding or limiting caffeine, spicy foods, high glycemic foods, fatty meals, ultra-processed foods, and alcohol, you can improve the quality of your sleep and wake up feeling refreshed and energized.
