Does raising your core body temperature by having a warm bath or exercising benefit the defense of when you are sick and therefore helps get better sooner?

There is some evidence to suggest that raising your core body temperature can help to improve your body's defense system and speed up the recovery process when you are sick.

How it works: When you raise your core body temperature, your body produces more white blood cells. White blood cells are essential for fighting infection and helping the body to heal. In addition, raising your body temperature can help to increase the production of interferon, a protein that helps to protect cells from viral infections.

What the research says: Several studies have shown that taking a warm bath can help to relieve cold and flu symptoms, such as congestion, sore throat, and muscle aches. One study, published in the journal Chest, found that taking a warm bath for 15 minutes can help to improve nasal airflow and reduce nasal congestion. Another study, published in the journal JAMA Internal Medicine, found that taking a warm bath can help to reduce muscle pain and stiffness associated with the flu.

Exercising can also help to raise your core body temperature and boost your immune system. One study, published in the journal Frontiers in Immunology, found that moderate-intensity exercise can help to increase the production of white blood cells and interferon. Another study, published in the journal Psychoneuroendocrinology, found that exercising can help to reduce stress and improve mood, which can also contribute to improved immunity.

What to keep in mind: While raising your core body temperature can help to improve your body's defense system, it is important to do so safely. If you have a fever, it is important to stay hydrated and to avoid raising your body temperature any further. You should also talk to your doctor before taking a warm bath or exercising if you have any concerns about your health.

Overall, there is some evidence to suggest that raising your core body temperature by having a warm bath or exercising can help to improve your body's defense system and speed up the recovery process when you are sick. However, it is important to do so safely and to talk to your doctor if you have any concerns.
