Bed rest has long been seen as a potential remedy for asthma symptoms. While it is true that rest can improve overall health, there is no evidence that bed rest alone can help improve the symptoms of asthma. In fact, too much rest can actually make asthma worse by decreasing the body's ability to fight off infections that can trigger asthma symptoms. The best way to manage asthma is to follow a comprehensive treatment plan, which includes avoiding triggers, taking prescribed medications, and using asthma-friendly exercise and lifestyle activities.
