Kiwi fruit has gained attention for its potential sleep-enhancing properties. In this blog, we'll explore the science behind kiwi’s impact on sleep and whether it could help your little one sleep better.
The research on kiwi and sleep: What do the studies say?
Several studies have examined the effects of kiwi fruit on sleep in adults. A study conducted by researchers in Taiwan found that participants who consumed two kiwis an hour before bed experienced significant improvements in sleep onset, duration, and quality. These participants not only fell asleep faster but also stayed asleep longer and had better overall sleep efficiency .
Another study highlighted the positive impact of kiwi on morning alertness, showing that participants felt more refreshed and less groggy upon waking . While these studies focus on adults, the underlying reasons why kiwi helps sleep offer some interesting insights for babies as well.
Why kiwi might improve sleep: Nutritional breakdown
Kiwi’s potential as a sleep-enhancer is largely linked to its impressive nutritional profile. Here's a breakdown of the key nutrients in kiwi that may promote better sleep:
- Serotonin: Kiwi contains high levels of serotonin, a neurotransmitter that plays a crucial role in regulating mood, appetite, and sleep. Serotonin is a precursor to melatonin, the hormone that controls the sleep-wake cycle .
- Antioxidants: Kiwi is rich in antioxidants, including vitamin C and vitamin E. These antioxidants help combat oxidative stress, which can interfere with sleep . Higher antioxidant intake has been associated with improved sleep quality in adults .
- Folate: Kiwi also provides folate (vitamin B9), which is essential for brain function and neurotransmitter production. Folate deficiency has been linked to insomnia and other sleep disturbances , so consuming folate-rich foods like kiwi could help support better sleep.
- Fiber: In addition to its other benefits, kiwi is high in fiber, which can help regulate digestion and prevent blood sugar spikes. For babies who may experience night wakes due to fluctuations in glucose levels, the fiber in kiwi could help promote more stable blood sugar levels overnight .
Can kiwi really help babies sleep?
The research on kiwi and sleep primarily focuses on adults. There are no studies confirming the effects of kiwi on infant sleep. Babies have different nutritional needs and metabolic rates than adults, so we wouldn’t assume the same results will apply. But it’s full of great antioxidants, delicious and super healthy so there’s no harm in trying!
