The Critical Role of Hydration in Fighting Infection
When you have a respiratory infection, your body loses more fluids than usual, especially if you have a fever. Staying well-hydrated is crucial for several reasons beyond just quenching your thirst. Drinking fluids helps to loosen and thin mucus in your nose and throat, making it easier to cough up and clear your airways. Furthermore, proper hydration maintains a healthy balance of electrolytes, which can become imbalanced during illness. It also supports your immune system by flushing toxins from your body, aiding in a quicker recovery.
Top Beverages to Sip When Sick
For those wondering what is the best thing to drink for a respiratory infection, a variety of options can provide both comfort and therapeutic benefits. The best drinks are warm, non-caffeinated, and packed with ingredients that offer soothing or anti-inflammatory properties.
Warm Water with Honey and Lemon This classic home remedy is highly effective for soothing a sore throat and suppressing a cough. Honey creates a protective coating on the throat, while lemon provides a boost of vitamin C and helps break down excess mucus. Note that honey should never be given to children under 1 year old due to the risk of infant botulism.
Herbal Teas Warm herbal teas offer a gentle way to hydrate while delivering beneficial compounds. Good options include:
- Ginger Tea: Known for its potent anti-inflammatory and antimicrobial properties, ginger can help reduce inflammation in the airways and ease nausea.
- Peppermint Tea: Contains menthol, which acts as a natural decongestant and can help open up nasal passages and clear congestion.
- Eucalyptus Tea: The compound eucalyptol has antimicrobial and anti-inflammatory effects that can reduce inflammation and help clear mucus.
- Licorice Root Tea: Used in traditional medicine to soothe coughs and sore throats, licorice root has anti-inflammatory and expectorant properties.
Clear Broths and Soups Chicken soup isn't just a comfort food—it offers genuine benefits. The warm broth provides hydration and electrolytes, while the steam can help open airways. Some research suggests that chicken soup may also have a mild anti-inflammatory effect. For vegetarians, vegetable or bone broths are excellent alternatives.
Electrolyte Solutions For infections accompanied by vomiting or diarrhea, electrolyte drinks like diluted sports drinks or oral rehydration solutions are essential to prevent dehydration and restore mineral balance. Diluting with water is recommended to avoid excessive sugar.
Fruit Juices and Smoothies Fresh, 100% fruit juices are a source of vitamins and minerals, but they should be consumed in moderation due to high sugar content, which can cause diarrhea in some individuals. Smoothies can be a good option if a sore throat makes eating difficult and can be packed with nutritious fruits and vegetables like spinach and pineapple, which contains the anti-inflammatory enzyme bromelain.
Beverages to Avoid
Some drinks can hinder your recovery or worsen symptoms. It's best to steer clear of these when you're under the weather.
- Caffeinated Drinks: Beverages like coffee, energy drinks, and some sodas act as diuretics, causing your body to lose more fluid and leading to dehydration.
- Alcohol: Alcohol is also dehydrating and can weaken your immune system, which prolongs your recovery time.
- High-Sugar Drinks: Excessive sugar can suppress the immune system and increase inflammation in the body. Stick to fresh juices in moderation over sugary sodas or sweetened teas.
- Dairy Products (if sensitive): While not a concern for everyone, dairy products can increase mucus production in some individuals, potentially worsening congestion and coughing.

| Smoothie | Nutrient-dense, easy to swallow, soothing | Fruits, vegetables, plant-based milk | When solids are hard to eat | Avoid excessive sugar |
The Importance of Overall Care
While what you drink is important, it's part of a larger recovery strategy. The NHS recommends getting plenty of rest, raising your head with extra pillows while sleeping, and using over-the-counter pain relievers for fever or aches. A cool-mist humidifier or breathing in steam from a hot shower can also provide significant relief from congestion and coughing by moisturizing your airways. If symptoms worsen, or if you have a severe lower respiratory tract infection, it is crucial to consult a healthcare professional. A Cochrane review noted the lack of definitive evidence for aggressive fluid increases in lower respiratory tract infections, highlighting the need for caution in such cases.
Conclusion
The best thing to drink for a respiratory infection is a warm, soothing, and hydrating fluid. Options like hot water with honey and lemon, ginger or peppermint herbal teas, and clear broths not only help combat dehydration but also actively work to alleviate uncomfortable symptoms like sore throats and congestion. Conversely, avoiding dehydrating beverages such as alcohol and caffeine is important for supporting your immune system. By focusing on smart hydration choices and combining them with plenty of rest, you can give your body the best possible chance to recover efficiently and comfortably.
