What Should I Drink When I’m Sick?

Illness, whether a common cold or a more severe virus, places significant demands on your body, often leading to a rapid loss of fluids and essential minerals. Symptoms like fever, vomiting, diarrhea, and increased mucus production contribute to fluid imbalance and dehydration. Maintaining fluid equilibrium is a necessity that supports the immune system, regulates body temperature, and helps thin secretions for easier clearance. A strategic approach to what you drink is fundamental for managing symptoms and promoting recovery.

Essential Fluids for Rehydration and Electrolyte Balance

When the body is fighting an infection, fluid is lost through increased sweating from fever or excessive output from the gastrointestinal tract due to vomiting or diarrhea. This fluid loss depletes the body’s store of electrolytes, which are minerals like sodium, potassium, and chloride needed for nerve function, muscle contraction, and fluid balance. Plain water is the foundational choice for volume replacement, but it must be supplemented with electrolytes to correct the imbalance.

Oral Rehydration Solutions (ORS) are specifically formulated to address fluid loss, offering the most efficient means of rehydration. These solutions utilize a transport mechanism in the small intestine where glucose and sodium are absorbed together. The World Health Organization (WHO) and UNICEF-recommended ORS formula has a precise ratio of sugar and salt to maximize water absorption and prevent worsening diarrhea from excess sugar. Many sports drinks lack this precise balance and may contain too much sugar, which can draw water into the intestine and worsen diarrhea.

Clear broths, such as chicken, beef, or vegetable broth, serve as an excellent source of both fluid and sodium, a primary electrolyte lost during illness. The warmth of the broth is soothing to a sore throat, and the steam acts as a gentle decongestant. Broths also provide small amounts of easily digestible nutrients, making them a suitable option when the stomach cannot tolerate solid foods.

Comforting Beverages for Symptom Management

Beyond basic rehydration, certain beverages offer targeted relief for common symptoms and provide comfort during recovery. Warm drinks are effective because the heat helps to thin mucus secretions in the nasal passages and chest, aiding in clearing congestion. Herbal teas, such as chamomile, are recommended for their mild anti-inflammatory properties and their ability to promote rest, which supports immune function.

A simple mixture of warm water, lemon, and honey is a time-tested remedy for cough and throat irritation. Honey acts as a demulcent, coating the throat’s mucosal lining to soothe irritation and suppress coughing. Lemon, while providing a small amount of Vitamin C, primarily helps to break down and thin thick mucus, making it easier to expel.

For individuals experiencing nausea or an upset stomach, ginger-based drinks offer a natural antiemetic effect. The active compounds, gingerols and shogaols, interact directly with the gastrointestinal tract to accelerate stomach emptying and block neurotransmitters that trigger the vomiting reflex. A strong ginger tea, made from steeping fresh or dried ginger, can be consumed in divided doses for nausea relief. Peppermint tea also helps calm a mild upset stomach by relaxing painful muscle contractions in the digestive tract.

Drinks to Limit or Eliminate When Ill

Certain popular beverages can impede recovery and should be limited or avoided when you are sick. Highly caffeinated drinks, including coffee, energy drinks, and some sodas, should be approached with caution. Caffeine is a diuretic, promoting fluid loss through increased urination, potentially compounding dehydration caused by fever or gastrointestinal distress. Caffeine can also interfere with sleep, which is crucial for the body’s immune system to function effectively and recover.

Alcohol is strongly discouraged because it is a diuretic that can significantly worsen dehydration and interfere with the immune response. Alcohol consumption is known to suppress immune function, slowing the body’s ability to fight off infection. A serious concern is the risk of a toxic interaction with common cold and flu medications, such as acetaminophen, which can lead to liver damage.

Drinks with excessive simple sugars, including many fruit juices and non-ORS sports drinks, should be limited when experiencing diarrhea or vomiting. The high concentration of sugar creates an osmotic effect in the intestines, drawing more water into the bowel. This influx of fluid can worsen diarrhea and exacerbate gastrointestinal upset, counteracting efforts to rehydrate.
