4 min read

According to a systematic review published in Nutrients in 2025, consuming soup may modestly reduce the severity and duration of symptoms from respiratory infections. But does soup actually help when you are sick beyond providing a warm, comforting placebo effect? The answer is yes, thanks to a combination of scientifically-backed benefits.

Quick Summary

Soup provides vital hydration and electrolytes, while the warmth and steam can soothe a sore throat and relieve nasal congestion. Its nutrient-dense ingredients can also have anti-inflammatory effects and support the immune system.

Key Points

  • Enhanced Hydration: Soup, especially broth-based varieties, helps replenish fluids and electrolytes lost during illness from fever, sweating, or vomiting.

  • Symptom Soothing: The warmth and steam from hot soup can effectively soothe a sore throat and act as a natural decongestant by thinning mucus in the nasal passages.

  • Immune System Support: Ingredients like chicken, garlic, and leafy greens provide essential protein, vitamins, and antioxidants needed for a strong immune response.

  • Anti-Inflammatory Effects: Many soups contain ingredients like ginger, turmeric, and garlic, which have anti-inflammatory properties that can help reduce illness-related inflammation.

  • Easily Digestible Nutrition: For those with a low appetite or upset stomach, soup provides easily digestible calories and nutrients, ensuring the body has fuel to recover.

  • Psychological Comfort: The act of being served a warm bowl of soup offers a significant psychological boost, reducing stress and promoting a sense of being cared for, which aids in recovery.

For generations, a warm bowl of soup has been the go-to remedy for anyone feeling under the weather. Whether it's chicken noodle, vegetable broth, or a spicy tom yum, this classic comfort food is often the first thing a loved one offers when you're sick. While the psychological comfort is undeniable, science confirms that soup offers real, tangible benefits for a recovering body.

The Power of Hydration and Electrolytes

One of the most critical aspects of recovery from illness, especially colds and the flu, is staying properly hydrated. Fever, sweating, and a runny nose can lead to significant fluid loss, putting you at risk of dehydration. This is where soup truly shines.

  • Replenishes fluids: Broth-based soups are an excellent source of fluids, helping to replenish the water lost during sickness.
  • Restores electrolytes: Unlike plain water, soup often contains electrolytes like sodium and potassium. These minerals are essential for maintaining proper fluid balance in the body and are lost when you sweat or have vomiting or diarrhea.
  • Gentle on the stomach: When your appetite is low or your stomach is upset, a large, heavy meal is often unappealing. The liquid nature of soup makes it much easier to digest, ensuring your body still receives the fluid and nutrients it needs to recover.

Symptom Relief: From Head to Throat

Beyond simple hydration, the physical properties of a hot bowl of soup can directly alleviate some of the most uncomfortable symptoms of a cold or flu.

Clearing Congestion with Steam

The steam rising from a hot bowl of soup acts as a natural decongestant. Inhaling the warm, moist air helps to moisten and thin mucus in the nasal passages and sinuses, making it easier to clear them and breathe more comfortably. Some studies have even suggested that chicken soup might be more effective at clearing nasal mucus than other hot liquids.

Soothing a Sore Throat

A warm broth can also provide immediate relief for an irritated and sore throat. The soothing liquid coats the throat, temporarily calming the pain and scratchiness that often accompany respiratory infections. Adding ingredients like ginger or honey (for adults) can amplify this effect.

Nutrient Boost for Immune Support

Your immune system requires significant energy and specific nutrients to fight off an infection effectively. A well-made soup can be a powerhouse of immune-boosting ingredients.

  • Protein: Chicken, lentils, or beans provide high-quality protein, which is vital for building and repairing body tissues, including immune cells and antibodies.
  • Vitamins and Minerals: Vegetables like carrots, celery, spinach, and onions are packed with vitamins A and C, antioxidants, and other minerals crucial for immune function.
  • Anti-inflammatory ingredients: Many popular soup additions, such as garlic, ginger, and turmeric, possess powerful anti-inflammatory and antioxidant properties that can help reduce the body's inflammatory response to illness.

A Comparison of Soup Options

Not all soups are created equal. Here is a comparison of different types to consider when you are sick.

The Placebo Effect and Psychological Comfort

While the scientific benefits are clear, the psychological aspect should not be overlooked. The nostalgic ritual of having a parent or loved one bring you a bowl of soup can be profoundly comforting. This psychological boost can help reduce stress and anxiety associated with being sick, allowing your body to focus its energy on healing. Sometimes, just feeling cared for can make all the difference in recovery.

Conclusion

In short, does soup actually help when you are sick? Absolutely. While it is not a magical cure that eliminates the virus, a nourishing bowl of soup offers a multitude of benefits that directly support the body's recovery process.
