The Science of Soup and Sleep
Beyond the undeniable comfort of a warm bowl, certain soups can contribute to a more restful night's sleep by leveraging specific nutrients and ingredients. The key is to consume a light, easily digestible meal that won't task your digestive system while you're trying to wind down. The warmth itself promotes relaxation, signaling to your body that it's time to rest.
Key Nutrients for a Better Rest
Several natural compounds found in certain soup ingredients are known to influence sleep quality:
- Tryptophan: This amino acid helps your body produce serotonin and melatonin, the hormones that regulate sleep cycles and mood. Chicken and eggs are excellent sources.
- Glycine: Abundant in bone broth, this amino acid has been shown to have a calming effect on the brain and nervous system, helping to reduce anxiety and promote deeper sleep.
- Magnesium: Known as the "relaxation mineral," magnesium helps calm the nervous system and promote muscle relaxation. Spinach, edamame, and almonds are great sources that can be incorporated into soups.
- Melatonin: While the body produces it naturally, some foods like corn and tart cherries contain melatonin and can help signal to your brain that it's time to sleep.
Recommended Soups for a Restful Night
Choosing the right soup means opting for smooth, broth-based options rather than heavy, chunky, or high-fat varieties. The goal is to nourish your body without disrupting your digestion.
Miso Soup
This traditional Japanese soup is made from a fermented soybean paste and is rich in amino acids that boost melatonin production. Instant packs are readily available, making it a quick and soothing nightcap. It's light, hydrating, and easy to digest, with a savory, comforting flavor.
Bone Broth
Sipping a warm mug of bone broth before bed is an excellent choice for sleep support. It’s naturally rich in glycine and magnesium, which aid relaxation and calm the nervous system. Additionally, bone broth's easy digestibility and gut-healing properties can prevent nighttime discomfort that disrupts sleep. A basic bone broth can be made by simmering beef or chicken bones with a touch of apple cider vinegar.
Smooth Vegetable Soups
Puréed soups made from gentle vegetables are very easy on the digestive system because the blending process essentially “pre-digests” the ingredients.
- Butternut Squash Soup: This naturally creamy soup is easy to digest and comforting. Butternut squash is also a good source of potassium and magnesium, which help promote muscle relaxation.
- Carrot Ginger Soup: The anti-inflammatory properties of ginger combined with the easy-to-digest carrots make this a soothing choice for upset stomachs.
Light Chicken Broth with Veggies
Simple chicken broth provides tryptophan, which helps in the production of calming hormones. Adding easily digestible, nutrient-dense vegetables like carrots and celery can further boost its benefits. Opt for low-sodium broth to avoid excess salt, which can cause dehydration and wakefulness.
What to Avoid Before Bed
Not all soups are created equal when it comes to sleep. Certain characteristics can lead to indigestion, heartburn, and discomfort, making it harder to fall and stay asleep.
- Heavy, Cream-Based Soups: These can be high in fat and calories, taking longer for your body to digest and potentially causing discomfort.
- Spicy Soups: Ingredients like chili and other hot spices can cause indigestion and heartburn, which are major sleep disruptors.
- High-Fiber Ingredients: While healthy during the day, heavy additions like beans, lentils, and thick noodles can be slow to digest, leaving your system working overtime instead of winding down.
- Excessive Sodium: High-sodium content can lead to fluid retention and dehydration, which can negatively impact your sleep.
