According to a 2024 article from the American Heart Association, warm beverages and soups can provide temporary relief from cold symptoms by increasing mucus flow and hydrating the body. Beyond just comfort, there is a surprising amount of science behind this age-old remedy.

Quick Summary

Warm liquids and soups offer temporary relief from cold symptoms like congestion and sore throats. The steam helps loosen mucus, while the fluids aid hydration and provide comforting nutrients. Certain ingredients also offer anti-inflammatory or immune-supporting properties, contributing to overall wellness when sick.

Key Points

Symptom Relief: Warm food and liquids provide temporary relief for congestion and sore throats through steam and soothing warmth.
Enhanced Hydration: Consuming warm fluids like broths and teas helps combat dehydration caused by increased mucus and fever.
Immune Support: Nutrient-rich, warm foods like chicken soup and bone broth provide essential vitamins, minerals, and protein needed for a strong immune response.
Inflammation Reduction: Anti-inflammatory ingredients like ginger, honey, and garlic found in warm drinks and meals can help reduce inflammation.
Dispelling Myths: The belief that dairy increases mucus is largely a myth; its thicker texture can just create that sensation.
Avoid Dehydrating Items: When sick, avoid alcohol and caffeine, as they can worsen dehydration.
Comfort and Energy: Warm, digestible foods are often more appealing and provide necessary energy when appetite is low.

While the idea of a warm meal as a cure-all for a cold is a myth, there is solid scientific evidence supporting its ability to provide significant symptomatic relief and support the body's natural healing process. A cold is a viral infection that must run its course, but the right food choices can make the journey far more comfortable.

The Soothing Power of Warmth

When you're under the weather, a hot meal or drink can feel like a comforting hug. This isn't just a placebo effect; the warmth has a direct impact on your body. The heat from liquids and vapor can help loosen congestion and soothe an irritated throat, making it easier to breathe and swallow. This is one of the main reasons chicken soup has been a go-to cold remedy for generations. The steam you inhale from the hot bowl helps open up stuffy respiratory passages, providing temporary relief.

The Importance of Hydration

Staying hydrated is crucial when fighting a cold, as your body loses fluids through mucus production and sweating, especially if you have a fever. Warm liquids can be an excellent way to replenish these fluids. Dehydration can worsen symptoms like headaches and fatigue, making adequate fluid intake a top priority. Opt for clear broths, herbal teas, or warm lemon water with honey to both hydrate and soothe your throat.

Nutritional Support When You're Sick

When your appetite is low, it's essential to choose nutrient-dense, easy-to-digest foods that fuel your immune system. Warm foods are often easier on a sensitive stomach. A nutrient-rich broth, for example, provides vitamins, minerals, and proteins that support your body's defenses.

Beneficial Ingredients in Warm Foods

Ginger: Known for its anti-inflammatory properties, ginger can help calm the inflammatory response associated with a cold. A simple warm ginger tea can be a soothing remedy.
Honey: Honey has antimicrobial properties and can coat an irritated throat, reducing the urge to cough. It's effective for both adults and children over one year old.
Garlic: Studies have suggested that garlic's antiviral properties may help reduce the severity and duration of cold symptoms. Adding it to warm soups is an easy way to incorporate it.
Spicy Foods: Ingredients like capsaicin in chili peppers can help thin mucus, clearing nasal passages and providing relief from congestion.

The Myth About Dairy

A persistent myth suggests that dairy products increase mucus production and should be avoided when sick. However, studies show this is not the case for most people. The sensation of thicker mucus is likely due to the texture of the milk combining with saliva, not an increase in production. If you enjoy yogurt or milk, there's no need to avoid it unless you have an existing intolerance.

Foods and Drinks to Avoid

Just as some foods can help, others can hinder your recovery. To feel better faster, avoid things that can cause inflammation or dehydration.

Alcohol and Caffeine: Both are diuretics that can worsen dehydration, which you need to avoid when sick.
Sugary Drinks and Sweets: Refined sugar can increase inflammation in the body and may hinder the immune system.
Spicy Foods (with caution): While capsaicin can thin mucus, highly spicy foods can also cause stomach upset or aggravate an already irritated throat.
