Warm, comforting, and packed with nutrients, a bowl of soup is a classic remedy for feeling under the weather, and scientific evidence backs up these claims. When you have a cough, the right soup can provide much-needed relief by soothing your throat, clearing congestion, and giving your immune system a boost.
The Science Behind Soup for a Cough
The Power of Warm Liquids
Any warm, non-caffeinated liquid can provide comfort when you are sick, but soup offers several distinct advantages. Warm broth soothes an irritated throat, which can reduce the urge to cough. It also helps keep you hydrated, which is crucial when you are fighting an infection and may have a fever. Proper hydration thins mucus, making it easier to expel and clearing congested nasal passages.
The Role of Steam
The steam rising from a hot bowl of soup can be a surprisingly effective decongestant. Inhaling the warm vapors helps to open nasal passages and loosen thick mucus in the respiratory tract. This is particularly helpful for chesty coughs and sinus congestion that often accompany a cold.
Nutrients and Anti-Inflammatory Effects
Certain ingredients commonly found in soup can actively help your body combat illness. For instance, the protein in chicken supports immune function by providing the building blocks for creating antibodies. Studies have also shown that chicken soup can inhibit the movement of neutrophils, a type of white blood cell, to the upper respiratory tract, which helps reduce inflammation and ease stuffiness. Beyond chicken, ingredients like garlic and ginger are well-known for their anti-inflammatory and antioxidant properties, which can help calm irritation and support a faster recovery.
The Best Soups to Combat a Cough
Clear Broth-Based Soups
- Classic Chicken Noodle Soup: This staple is beneficial for many reasons. It provides hydrating broth, immune-supporting protein from the chicken, and vitamins from vegetables like carrots, onions, and celery. The mild flavor is often appealing even when your appetite is low.
- Ginger Carrot Soup: This vegetarian option combines the anti-inflammatory benefits of ginger with the vitamins from carrots, which support immune response. The sweetness of the carrots and warmth of the ginger create a soothing effect.
- Tomato Peppercorn Clear Soup: Rich in immune-boosting vitamin C and antioxidants from tomatoes, this light soup uses black peppercorns, which have antiviral properties, and ginger to create a flavorful remedy.
Nutrient-Packed Vegetable Soups
- Mixed Vegetable and Barley Soup: This wholesome soup adds fiber and nutrients from a variety of vegetables and barley. It supports gut health, which is closely linked to immune function.
- Garlic and Ginger Soup: For a potent remedy, a broth infused with high quantities of fresh garlic and ginger is a powerful anti-inflammatory and antibacterial choice.
Soups to Approach with Caution (or Avoid)
Cream-Based and Dairy-Heavy Soups
For some people, particularly those with a phlegmy cough, dairy products can thicken existing mucus and make it harder to expel. Soups made with milk, cream, or excessive cheese may worsen congestion for certain individuals. Opt for broth-based versions if you notice this effect.
Heavily Processed and Fried Soups
Canned or instant soups can contain very high levels of sodium, which can lead to dehydration. They also often contain preservatives and lack the fresh, nutrient-dense ingredients that are most beneficial when you're sick. Fried ingredients, like crispy onions or croutons, and fatty broths can increase inflammation and be difficult for a weakened system to digest.
Overly Spicy Soups
While spicy foods can temporarily thin mucus and clear nasal passages for some, they can also irritate an already inflamed throat. In sensitive individuals, this irritation can trigger more coughing, making things worse in the long run.

How to Maximize the Benefits of Your Soup
- Add Fresh Ingredients: Include fresh garlic, ginger, and turmeric for their potent anti-inflammatory and antiviral properties.
- Use Quality Broth: Choose low-sodium or homemade broth to avoid excess salt that can lead to dehydration.
- Top with Herbs: A sprinkle of fresh black pepper or cilantro can add flavor and additional health benefits.
- Inhale the Steam: Before eating, take a moment to breathe in the steam from the bowl to help clear your nasal passages.
- Sip Slowly: Take your time to sip the warm broth, allowing it to coat and soothe your irritated throat.
