What are good fluids to drink when you have a fever?

4 min read

According to the Mayo Clinic, a fever can increase fluid loss and lead to dehydration, making it crucial to understand what are good fluids to drink when you have a fever. Proper hydration is a cornerstone of recovery, helping your body regulate temperature, flush toxins, and support the immune system.

Quick Summary

This guide details the best drinks for fever management, focusing on hydration and electrolyte replenishment. It covers options like water, oral rehydration solutions, broths, and herbal teas, as well as beverages to avoid.

Key Points

  • Prioritize Hydration: A fever increases fluid loss through sweating, making proper hydration essential to prevent dehydration and support immune function.

  • Start with Water: Plain water is the most effective and gentle fluid for staying hydrated during a fever, especially when sipped frequently.

  • Replenish Electrolytes: For significant fluid loss from sweating or vomiting, oral rehydration solutions (ORS) or natural options like coconut water are vital for replacing lost minerals.

  • Consider Soothing Warmth: Clear broths and caffeine-free herbal teas (like ginger or chamomile) can be comforting, and the steam can help with congestion.

  • Avoid Dehydrating and Sugary Drinks: Stay away from alcohol, caffeinated beverages, and high-sugar drinks like undiluted juices and sodas, as they can worsen dehydration.

  • Listen to Your Body: Pay attention to signs of thirst and dehydration. Sip fluids consistently, especially if appetite is low, and seek medical advice for severe symptoms.

  • Be Mindful of Special Needs: Infants, young children, and the elderly are at higher risk for dehydration and may require specific hydration strategies. Always consult a pediatrician regarding children.

Why Proper Hydration is Crucial During a Fever

When your body is fighting an infection, a fever is a natural immune response. The elevated body temperature often leads to increased sweating, and in some cases, vomiting or diarrhea can further deplete your body's fluid and electrolyte reserves. Dehydration can intensify symptoms like fatigue, dizziness, and headache, potentially slowing down your recovery. Maintaining proper fluid balance is essential for several reasons:

  • Regulating Body Temperature: Sweating is a cooling mechanism, and your body needs adequate fluid to produce sweat effectively and prevent overheating.
  • Supporting the Immune System: Hydration helps immune cells function optimally, making it easier for your body to combat the underlying infection.
  • Replenishing Electrolytes: Essential minerals like sodium and potassium, lost through sweating, are vital for muscle and nerve function. Replacing them is key to feeling better.
  • Flushing Toxins: Increased fluid intake helps your kidneys and liver process and eliminate waste products and toxins from the body.

The Best Fluid Choices for a Fever

Choosing the right fluids can significantly impact your comfort and recovery speed. Here are some of the top recommendations:

Water

Plain water is always the safest and most effective choice for hydration. Sip it consistently throughout the day, rather than drinking large amounts at once, which can upset a sensitive stomach.

Oral Rehydration Solutions (ORS)

For fevers accompanied by vomiting or diarrhea, water alone may not be enough. ORS, like Pedialyte, are formulated with precise amounts of water, sugar, and electrolytes to replace lost fluids and minerals quickly and effectively.

Clear Broths and Soups

Nutrient-rich broths (chicken, beef, or vegetable) provide gentle hydration and are easy on the stomach. They offer some calories, protein, and electrolytes, which is especially helpful when your appetite is low. The warmth can also be soothing for a sore throat and can help loosen congestion.

Herbal Teas

Warm, caffeine-free herbal teas can be incredibly comforting and offer additional benefits.

  • Ginger tea: Known for anti-inflammatory properties and can help soothe nausea.
  • Chamomile tea: Can promote relaxation and sleep, which are both vital for recovery.
  • Peppermint tea: May have a natural cooling effect and can help with congestion. Adding a little honey to your tea can also help suppress a cough, but avoid giving honey to infants under one year old.

Coconut Water

As a natural source of electrolytes like potassium and magnesium, coconut water can be an excellent option for rehydration. It's a gentler alternative to sugary sports drinks and is easy to digest.

Diluted Fruit Juice

If you need a bit of flavor, diluted fruit juice can provide some vitamins. However, be cautious with pure, undiluted juices, as their high sugar content can irritate the stomach or worsen diarrhea. Diluting it with water is the best approach.

Fluids to Avoid When Sick with a Fever

Just as important as knowing what to drink is knowing what to avoid to prevent slowing down your recovery. Stay away from:

  • Caffeinated beverages (coffee, black tea, energy drinks): Caffeine is a diuretic, meaning it increases urine output and can contribute to dehydration.
  • Alcohol: Alcohol weakens the immune system and is highly dehydrating.
  • Sugary drinks (soda, fruit punches): The high sugar content can cause stomach irritation and potentially worsen diarrhea, hindering your body's ability to absorb water effectively.
  • Dairy: While not universally problematic, some people find dairy can thicken mucus and exacerbate congestion. Listen to your body and avoid if it worsens your symptoms.

Comparison Table: Fever Fluids

Fluid Type Best For Key Benefits Potential Drawbacks
Water Basic hydration, flushing toxins Most effective and simple; no additives Lacks electrolytes for heavy sweating
Oral Rehydration Solution (ORS) Moderate to severe dehydration (vomiting/diarrhea) Replenishes electrolytes quickly Can be expensive; some may dislike taste
Clear Broth Low appetite, congestion, nausea Soothing, provides nutrients and electrolytes Sodium content should be monitored
Herbal Tea Sore throat, congestion, sleep Soothing, anti-inflammatory properties Must be caffeine-free; can have added sugar
Coconut Water Natural electrolytes, general hydration High in potassium, low in sugar May not be universally available
Diluted Fruit Juice Flavor, mild vitamin intake Provides flavor and some nutrients High sugar if not diluted; can cause stomach upset

A Note on Children and the Elderly

Infants, young children, and the elderly are more susceptible to dehydration, so special attention to fluid intake is critical. For children under one year, always consult a pediatrician before giving anything other than breast milk or formula. Oral rehydration solutions designed for children, like Pedialyte, are a good option for replenishing electrolytes. In the elderly, a diminished sense of thirst can increase the risk of dehydration, so consistent reminders to sip fluids are important. For both groups, if symptoms of severe dehydration (like infrequent urination, no tears, or extreme weakness) appear, seek medical attention immediately.

Conclusion

Staying well-hydrated is arguably the most important home remedy for managing a fever. While plain water is the cornerstone of hydration, supplementing with electrolyte-rich fluids like oral rehydration solutions, clear broths, and coconut water can accelerate recovery, especially when experiencing sweating, vomiting, or diarrhea. The comforting warmth and therapeutic properties of herbal teas, such as ginger or chamomile, also make them a valuable addition to your fluid intake. Conversely, avoiding dehydrating and sugary drinks like alcohol, coffee, and soda is crucial. By being mindful of the fluids you consume, you can support your body's natural healing processes and get back on your feet faster. As always, for persistent high fevers or concerning symptoms, consulting a healthcare professional is the best course of action.
