With winter in full swing, the cold and flu season is at its peak. Even the most skeptical of us may be tempted to turn to old wives’ tales and folk remedies when we have a runny nose and a pounding head. However, these remedies can be ineffective and even harmful to our health. For instance, the saying “feed a cold, starve a fever” is not only misleading but can also have a negative impact on our health. While it is important to nourish our bodies when we have a cold, it is equally essential to provide our bodies with energy and nutrients when we have a fever. A fever, like excess mucus, is one of the body’s defense mechanisms to combat bacteria and viruses. Dr. Pedro Piedra, a professor at the Baylor College of Medicine, explained that high temperatures caused by fevers can hinder the replication of disease-causing organisms, particularly viruses.

During a fever, the body’s metabolic energy demand increases, requiring more, not less, energy. Studies have shown that as little as a 1-degree Celsius rise in body temperature can lead to a 10% increase in calorie consumption. Additionally, the body tries to cool down by increasing respiration, leading to higher energy and water loss. Increased water intake is crucial during a fever, while consuming solid food may be challenging due to nausea and malaise. Dr. Piedra recommends consuming bland foods such as chicken or lamb soup, as they provide both calories and hydration. In addition to combatting infection, fevers can also serve as warning signs. It is important to keep an eye on high fevers, especially in children, and seek medical advice when feeling unwell with a high fever.
