Understanding the Science: Why Does Olive Oil Make You Sleepy?

3 min read

A significant portion of the population struggles with getting restful sleep. Yet, the connection between olive oil and improved sleep is often overlooked.

Quick Summary

The sleepiness some experience after consuming olive oil is linked to its effects on digestion, blood sugar, and hormone production. Healthy fats promote satiety and calm the body.

Key Points

  • Blood Sugar Stabilization: Olive oil's monounsaturated fats help stabilize blood sugar, preventing energy crashes after meals.

  • Hormone Production: Olive oil supports the absorption of tryptophan, which is converted to serotonin and melatonin, aiding the sleep cycle.

  • Reduced Inflammation: Olive oil's anti-inflammatory compounds reduce systemic inflammation, promoting sleep.

  • Enhanced Digestion: Olive oil can improve digestion and promote a feeling of fullness, which can lead to less gastrointestinal discomfort during the night.

  • Natural Relaxation: The combined effects of stabilized blood sugar and reduced inflammation can create a calmer state, potentially promoting a deeper sleep.

The Postprandial Phenomenon: Why We Get Sleepy After Eating

Postprandial somnolence, commonly known as a food coma, is a natural response to digestion. After a substantial meal, the body directs significant energy toward the digestive process. This shift in blood flow away from the brain and toward the gut can lead to feelings of lethargy. This phenomenon is not unique to olive oil but is a contributing factor when consuming a meal rich in fats. The specific effect olive oil has on the body, however, goes beyond this general digestive process.

The Hormonal Connection to Sleepiness

When food is consumed, the body’s hormonal balance is affected. For instance, consuming healthy fats, like those found in olive oil, can influence the production of sleep-related hormones. Tryptophan, an amino acid, is a precursor to serotonin and melatonin. Melatonin is the hormone responsible for regulating sleep-wake cycles, or circadian rhythm. Insulin spikes can alter the ratio of amino acids in the bloodstream, allowing more tryptophan to cross the blood-brain barrier and convert into serotonin and then melatonin, potentially inducing sleepiness. Olive oil's role in moderating these insulin spikes is a key factor.

The Impact on Blood Sugar Levels

One of the most significant ways why does olive oil make you sleepy is its impact on blood sugar. The healthy monounsaturated fats in olive oil help stabilize blood glucose levels. Instead of a rapid spike and crash that can occur with high-carb meals, olive oil promotes a slower, more sustained release of energy. This prevents the rapid crash that can leave you feeling tired. This effect is particularly noticeable in the evening, as it can help promote a calm, sustained state of energy, which the body can then convert into a restful, uninterrupted sleep cycle.

Anti-inflammatory Effects for Better Rest

Chronic inflammation can disrupt sleep patterns, leading to restless nights. Olive oil is well-known for its anti-inflammatory properties, thanks to compounds like oleocanthal and its high content of oleic acid. By reducing inflammation throughout the body, olive oil can help create a more favorable environment for deep, restorative sleep. This is particularly beneficial for individuals with inflammatory conditions that might interfere with their slumber.

How to Incorporate Olive Oil for Restful Sleep

To experience the potential sleep benefits of olive oil, consider these additions to your evening routine:

  • A Spoonful Before Bed: Some people report that taking a small spoonful of extra virgin olive oil before bed helps them feel more satiated, preventing late-night hunger pangs that could wake them up.
  • Evening Meals: Drizzle extra virgin olive oil over dinner salads or incorporate it into your evening meal to enhance the absorption of fat-soluble vitamins and support digestion.
  • Infused Oil: Create a relaxing experience by infusing olive oil with calming herbs like lavender and massaging a small amount into your temples or adding it to a warm bath.

Comparison: Olive Oil vs. Other Fats for Sleep

Feature Olive Oil Refined Seed Oils (e.g., Canola) Saturated Fats (e.g., Butter)
Fat Profile High in monounsaturated fats High in polyunsaturated fats High in saturated fats
Effect on Blood Sugar Stabilizes blood sugar levels Can contribute to unstable blood sugar Often consumed with carbs, causing spikes
Digestive Ease Supports digestion Difficult to digest for some Can be heavy and slow digestion
Anti-inflammatory Contains strong anti-inflammatory compounds (oleocanthal) May be pro-inflammatory when over-processed Neutral, but often combined with inflammatory foods
Sleep Hormones Aids in tryptophan absorption Minimal or no effect Minimal or no effect

Conclusion: Olive Oil as a Potential Sleep Ally

The notion that olive oil can make you sleepy is rooted in several scientific principles. The healthy fats stabilize blood sugar, promote satiety, and aid in the absorption of sleep-regulating hormones like melatonin. Furthermore, its anti-inflammatory properties help calm the body and pave the way for more restorative rest. While not a magic cure for insomnia, incorporating high-quality extra virgin olive oil into your diet, particularly in the evening, may offer a gentle, natural way to support a better night's sleep. As with any dietary change, moderation is key, and it is always wise to consult a healthcare professional for personalized advice.

Yes, extra virgin olive oil is generally better for promoting sleep because it contains a higher concentration of beneficial compounds, like anti-inflammatory polyphenols, that are largely preserved due to minimal processing.

The effect of olive oil on sleep can vary among individuals. While many find it beneficial, others may not notice a significant difference.

For optimal sleep benefits, you can take a small spoonful of extra virgin olive oil before bed, or incorporate it into your evening meal, such as drizzling it over a salad or vegetables.

Some evidence suggests that the anti-inflammatory properties and blood sugar stabilizing effects of olive oil may help manage certain factors that contribute to insomnia, but it is not a proven cure.

While generally safe, excessive consumption can lead to digestive discomfort or an unwanted increase in caloric intake. It is recommended to start with a small amount and monitor your body's response.
