Does spinach help with sleep disruption during perimenopause?

Spinach contains several nutrients with documented roles in sleep regulation, making it a genuinely useful food for perimenopausal women struggling with disrupted sleep. While no single food fixes the hormonal underpinning of perimenopausal sleep problems, spinach addresses multiple biological pathways that influence sleep quality, sleep onset, and nighttime awakening.

Magnesium is the most compelling nutrient. Cooked spinach provides approximately 78mg of magnesium per 100 grams. Magnesium supports sleep through its action on GABA-A receptors. GABA is the brain's primary inhibitory neurotransmitter, responsible for the neurological quieting that allows sleep to occur and to be maintained. Magnesium enhances GABA receptor sensitivity, making inhibitory signaling more effective. A 2012 clinical study by Abbasi and colleagues found that magnesium supplementation improved measures of sleep quality including sleep efficiency, sleep time, and early morning awakening in older adults with poor sleep. Magnesium deficiency is common in perimenopausal women, as hormonal fluctuations and elevated stress hormones increase urinary magnesium excretion.

Folate supports the melatonin synthesis pathway. Cooked spinach provides around 146 micrograms of folate per 100 grams. Folate is a cofactor in serotonin production, and serotonin is the precursor from which melatonin is synthesized in the pineal gland as darkness falls. When folate is insufficient, serotonin synthesis is limited, which in turn reduces melatonin availability. Adequate melatonin is essential for a robust sleep signal at night and for maintaining sleep through the early morning hours.

Spinach also provides a small amount of tryptophan through its protein content. Tryptophan is the amino acid precursor to serotonin and ultimately melatonin. While spinach is not a concentrated tryptophan source the way turkey or pumpkin seeds are, it contributes to tryptophan availability within a mixed diet.

Blood glucose stability is a practically important factor for perimenopausal sleep. The hormonal changes of perimenopause reduce insulin sensitivity, making blood sugar drops more likely during the night. When blood glucose falls during sleep, the body releases cortisol and adrenaline to raise it, causing nighttime awakening, racing heart, and difficulty returning to sleep. These episodes are sometimes mistaken for or combined with night-sweat-driven awakenings. Spinach's fiber content helps buffer the glycemic impact of the evening meal, contributing to more stable overnight blood glucose.

Night sweats are the most common cause of sleep disruption in perimenopause, and while spinach has no direct phytoestrogenic effect on vasomotor symptoms, its anti-inflammatory compounds, kaempferol and quercetin, may reduce the background inflammatory load that worsens symptom severity. And better blood sugar stability, as noted above, can reduce the adrenergic nighttime events that compound genuine night sweats.

Iron is worth noting in the sleep context as well. Insufficient iron has been linked to restless legs syndrome, a condition that causes uncomfortable sensations in the legs at rest and an urge to move them, which significantly disrupts sleep onset and maintenance. Spinach provides non-heme iron enhanced by its own vitamin C content, making it a useful dietary iron source.

The PeriPlan app can help you log your diet and sleep quality together, so you can track whether dietary patterns like consistently including magnesium-rich vegetables correlate with better sleep over several weeks.

Practical guidance: Eat cooked spinach several times per week, ideally as part of an evening meal that also includes protein, complex carbohydrates, and healthy fats. Avoid eating very late at night, as digestion and blood sugar fluctuations can also disrupt sleep. Pair spinach with pumpkin seeds, almonds, or legumes, which are also magnesium-rich, to collectively support adequate dietary magnesium intake.

When to see a doctor: Sleep disruption that is severe, persistent beyond a few weeks, or significantly impairing daytime functioning warrants medical evaluation. Sleep apnea, thyroid dysfunction, depression, anxiety disorders, and restless legs syndrome are treatable conditions that can masquerade as or worsen perimenopausal sleep problems. Cognitive behavioral therapy for insomnia (CBT-I) is an evidence-based treatment that does not require medication.
