Understanding the Meaning and Taking Action

The age-old saying „feed a cold, starve a fever“ has been passed down through generations as a piece of health advice. The idea behind this saying is that when you have a cold, you should eat to help your body fight off the illness, while when you have a fever, you should refrain from eating to allow your body to focus on fighting the infection. However, recent medical knowledge suggests that this advice may not be entirely accurate.

The truth is that whether you have a cold or a fever, your body needs energy in the form of calories to support your immune system and aid in recovery. When you are sick, your immune system is working overtime to fight off the infection, which requires additional calories. Therefore, it is essential to provide your body with the necessary nutrients to support this process.

Dr. Albert Ahn, a clinical instructor of internal medicine at NYU Langone Health, explains that when you have a fever, your body’s metabolism increases as it tries to raise your body temperature to fight off the infection. This increased metabolic rate means that you may actually need more calories when you have a fever to support your body’s efforts to combat the illness.

In addition to providing your body with adequate calories, it is also crucial to stay hydrated when you are sick, especially when you have a fever. Fevers can lead to increased fluid loss through sweating, vomiting, or diarrhea, making it essential to replenish these fluids to prevent dehydration. Hydration is just as important as calorie intake when it comes to supporting your body’s immune response during illness.

While it may be challenging to eat when you are sick, there are some tips to help you consume nutrients and stay hydrated. Consuming fluids with calories, such as coconut water or sports drinks, can provide essential nutrients while keeping you hydrated. Additionally, hot liquids like herbal tea or broth can help thin mucus and provide critical nutrients to support your immune system.

It is essential to avoid certain foods and drinks when you are sick, as they can worsen symptoms or hinder your body’s ability to recover. Alcohol, caffeinated beverages, high-fat foods, and high-sugar foods should be avoided, as they can dehydrate you or increase inflammation in your body.

If you find that your symptoms are not improving or are worsening, it is crucial to seek medical attention. Certain warning signs, such as confusion, breathing problems, or a high fever that does not respond to treatment, may indicate a more serious underlying condition that requires medical intervention.

In conclusion, the saying „feed a cold, starve a fever“ may have some historical basis, but current medical knowledge suggests that it is essential to provide your body with adequate calories and hydration when you are sick, whether you have a cold or a fever. By eating nutrient-rich foods and staying hydrated, you can support your immune system and aid in your body’s recovery process. If you have concerns about your symptoms, it is always best to consult a healthcare provider for guidance and treatment.
