Do Baths Help When You’re Sick?

Baths are a traditional form of hydrotherapy used at home to ease the discomfort of common illnesses like the cold or flu. While a warm soak cannot cure an infection, it provides symptomatic relief and general comfort. This simple act of self-care offers a temporary respite from aches, congestion, and fever, promoting relaxation when the body needs it most.

How Water Temperature Affects Common Symptoms

Warm and hot water baths primarily help by generating steam, which is beneficial for respiratory symptoms. Inhaling the warm, moist air helps to thin and loosen mucus in the nasal passages and chest, temporarily relieving congestion. The heat also promotes vasodilation, a widening of blood vessels, which increases blood flow to the skin and muscles. This improved circulation helps ease muscle aches and stiffness, aiding relaxation and making it easier to fall asleep.

Conversely, when managing a mild to moderate fever, the focus shifts to lukewarm or tepid water. A bath that feels slightly cool to the touch, generally between 85 and 95 degrees Fahrenheit, encourages heat loss through evaporation from the skin’s surface. This gently reduces the body’s temperature without causing a sudden shock to the system. The water should not be cold, as this can trigger shivering, which generates heat and can raise the internal temperature.

Enhancing Relief with Bath Additives

Adding certain substances to bathwater can amplify the therapeutic effects of the soak and target specific symptoms. A popular addition is Epsom salt, or magnesium sulfate, which is used to help relax muscles and ease tension. The simple act of soaking in warm water aids in muscle relaxation, and the addition of salts is a long-standing folk remedy for body aches.

For respiratory relief, incorporating essential oils is effective through aromatherapy. The compounds in oils like eucalyptus and peppermint, specifically eucalyptol and menthol, are known to have decongestant properties. Adding a few drops allows the vapors to be inhaled with the steam, helping to clear airways and reduce sinus pressure. Essential oils must be diluted or mixed with a carrier like Epsom salts before adding them to the water to prevent skin irritation.

Certain additives are beneficial for soothing irritated skin that may accompany illness or fever. Colloidal oatmeal, which is finely ground oats, forms a protective barrier on the skin, helping to lock in moisture and ease inflammation. Similarly, a small amount of baking soda (sodium bicarbonate) can be added to the bath to help soothe minor skin irritation and itching. The use of these additives can be comforting when the skin is dry, itchy, or tender.

Safety Considerations and When to Avoid Bathing

Hydration is important when taking a bath while sick, especially when using warmer water. The heat from the bath, combined with a fever, can increase sweating and the risk of dehydration. It is crucial to drink water or an electrolyte solution before and after the bath to replace lost fluids. Keeping the bath duration short, around 10 to 20 minutes, minimizes the risk of overheating or becoming lightheaded.

Bathing should be avoided if certain symptoms are present. Individuals experiencing extreme weakness, severe dizziness, or a high risk of fainting should opt for a sponge bath instead. If a fever is over 103 degrees Fahrenheit, a bath is not the appropriate first step for temperature reduction, and medical advice should be sought. Additionally, those with open wounds, severe skin infections, or recent surgical incisions should avoid soaking in a tub to prevent irritation or infection.
