The Science Behind Beets and Sleep
Beets, particularly in juice form, contain nitrates that the body converts into nitric oxide. This molecule is a powerful vasodilator, meaning it helps to relax and widen blood vessels. This vasodilation effect is key to understanding why beets may aid sleep, especially for those with certain conditions. By improving circulation, beets can enhance oxygen delivery throughout the body, including to the brain and lungs. Improved oxygenation is a critical factor for maintaining restful, uninterrupted sleep.
Specifically for respiratory issues like sleep apnea, the bronchodilating properties that result from nitric oxide production can help widen air passages. This can reduce the likelihood of airway obstruction, a common cause of sleep disruption. For individuals with conditions like COPD, research has shown that concentrated beetroot juice before bed can improve sleep quality, increase deep sleep episodes, and elevate blood oxygen levels during the night.
Beyond Sleep: Nighttime Health Benefits
While the link to sleep is noteworthy, consuming beets at night offers a host of other health advantages that contribute to your overall well-being as you rest.
- Digestive Support: Whole beets are a great source of dietary fiber, which promotes healthy bowel movements and can prevent constipation. A comfortable digestive system is less likely to cause discomfort that can disturb sleep. For juiced beets, some fiber remains to help with gut health.
- Liver Detoxification: Beets contain compounds like betaine, which supports liver function and helps protect against fatty liver diseases. The liver is active in detoxification processes overnight, and beets can aid this natural function..
- Cardiovascular Health: The blood pressure-lowering effects of beets are well-documented. The nitrates help relax blood vessels, which can contribute to a more restful state and reduce stress on the cardiovascular system while you sleep..
- Antioxidant Power: Beets are rich in antioxidants and anti-inflammatory compounds, which help combat oxidative stress and cellular damage that occurs throughout the day. By consuming them at night, you provide your body with the tools to repair and regenerate while you sleep.
Raw vs. Cooked: What's Best at Night?
When considering how to incorporate beets into your evening routine, both raw and cooked preparations offer benefits, though with slightly different characteristics.
Raw Beets
- Pros: Maximize nutrient retention, especially for heat-sensitive compounds like certain vitamins and antioxidants. Excellent for juicing, which provides a fast-absorbing nutrient boost.
- Cons: Can be harder to digest for some people due to the raw fiber content, potentially causing gas or bloating that could disrupt sleep. The flavor is more earthy and intense.
Cooked Beets
- Pros: Generally easier to digest than raw beets, reducing the risk of nighttime digestive upset. Roasting or boiling can bring out a sweeter, milder flavor.
- Cons: Some vitamins, particularly Vitamin C, can be lost during the cooking process. Cooking can also lower the nitrate concentration, though it remains a significant source.
The Verdict: For optimal sleep-promoting effects, beet juice before bed provides a quick delivery of nitrates and nutrients without the fibrous bulk. However, for a gentler digestive experience, a small portion of cooked beets in a salad or as a side dish can also be beneficial.
Potential Downsides and Considerations
While beets are generally safe and healthy, there are a few considerations, especially when consuming them before bed.
Blood Sugar Levels: Beet juice, due to the removal of fiber during juicing, can cause a more rapid spike in blood sugar compared to eating whole beets. Individuals with diabetes should monitor their intake and consult a doctor.
Kidney Stones: Beets are high in oxalates, which can contribute to the formation of kidney stones in susceptible individuals. If you have a history of calcium oxalate kidney stones, it's wise to limit or avoid beet consumption and consult your physician.
Beeturia: Don't be alarmed if your urine or stool turns reddish or pink after consuming beets. This harmless condition is called beeturia and is temporary.
Conclusion
So, are beets good for you at night? For many, the answer is a resounding yes. The nitrates in beets, particularly when consumed as juice, can improve sleep quality by enhancing circulation and oxygen delivery, a benefit shown in studies on individuals with respiratory issues. Beyond sleep, beets offer nighttime digestive and liver support, plus powerful antioxidant benefits. While whole beets are an excellent fiber source, beet juice offers a faster way to absorb key nutrients before bed. However, individuals with diabetes or a history of kidney stones should exercise caution. By incorporating beets thoughtfully into your evening routine—perhaps as a small glass of juice or a side dish—you can tap into its natural power for a more restorative night's rest.

How to Incorporate Beets into Your Nightly Routine
To get the most out of beets for nighttime health, consider these options:
- Drink a small glass of beetroot juice an hour or two before bed. You can mix it with a little carrot or ginger juice to balance the flavor.
- Add roasted beets to your dinner salad. A simple, light side dish is a great way to benefit from the fiber and nutrients.
- Enjoy a small, simple beet and goat cheese salad as a light, yet satisfying, evening meal or snack.
- Blend cooked beets into a pre-bedtime smoothie with other relaxing ingredients like banana or nut butter.
Conclusion
