Does olive oil help with sleep disruption during perimenopause?

Extra virgin olive oil is not a sleep aid in the conventional sense, but it is a meaningful component of a dietary pattern that research has linked to better sleep quality, including in midlife women. Sleep disruption during perimenopause has multiple causes: night sweats that wake you up, anxiety that prevents falling asleep, cortisol dysregulation, and direct effects of declining estrogen and progesterone on sleep architecture. Diet influences several of these pathways.

A 2022 review by Gaeta and colleagues examined the relationship between Mediterranean diet adherence and sleep quality, finding that greater adherence to the Mediterranean dietary pattern was associated with better sleep quality, shorter sleep onset time, and fewer nighttime awakenings. Extra virgin olive oil is the foundational fat of the Mediterranean diet, so it is embedded in the pattern that produced these associations. The research does not single out olive oil as the active ingredient, and it would be misleading to suggest it does, but it is a core piece of the pattern.

The mechanisms linking diet to sleep during perimenopause are worth understanding. Systemic inflammation disrupts sleep architecture. Elevated inflammatory markers, including IL-6 and CRP, are associated with poorer sleep quality and more fragmented sleep in multiple studies. Oleocanthal in extra virgin olive oil inhibits COX-1 and COX-2 enzymes (Beauchamp et al., 2005, Nature), reducing pro-inflammatory prostaglandin production, which may help support the quieter inflammatory environment that healthy sleep requires.

Blood sugar stability through the night matters too. Blood glucose drops in the early morning hours can trigger cortisol release, which wakes you up and makes it hard to fall back asleep. Monounsaturated fats from olive oil slow digestion and contribute to more stable glucose levels after an evening meal, potentially reducing this pattern.

The polyphenols in extra virgin olive oil, particularly hydroxytyrosol, also support the gut microbiome by acting as prebiotics. Gut bacteria play a role in producing and metabolizing serotonin, which is the precursor to melatonin, the hormone that governs sleep timing. A healthier gut environment may therefore support better melatonin production indirectly, though this specific pathway is still being studied in human trials.

For practical use, using extra virgin olive oil as your primary fat throughout the day, around 2 to 4 tablespoons within a Mediterranean-style eating pattern, is what the research examined. For sleep specifically, it is worth considering the timing of your largest fat intake. A light evening meal centered on olive oil-dressed vegetables and lean protein is generally more sleep-supportive than a heavy, late-night meal, regardless of the fat source.

Alcohol is worth highlighting here because it is often perceived as sleep-promoting but actually fragments sleep architecture in the second half of the night. If you are using wine as part of your Mediterranean diet practice, keeping intake moderate is important for not undermining the sleep benefits of the overall pattern.

Tracking your sleep quality alongside dietary habits over several weeks can help you identify what is and is not working for your body. The PeriPlan app lets you log sleep patterns and symptoms daily, making it easier to see connections that are invisible when relying on memory alone.

When to see a doctor: If sleep disruption is severe, persistent across multiple weeks, leaving you significantly impaired during the day, or accompanied by symptoms like loud snoring or gasping (which may suggest sleep apnea, a condition that becomes more common after menopause), speak with your healthcare provider. A provider can evaluate whether night sweats, anxiety, or sleep apnea are primary drivers, and discuss evidence-based options including cognitive behavioral therapy for insomnia (CBT-I), hormone therapy, or other interventions.

Olive oil is safe for most people at culinary doses. It is calorie-dense and is best used as a replacement for other fats rather than an addition to an already high-calorie diet.
