What should asthmatics do to help strengthen their lungs?

Engaging in specific breathing exercises can significantly benefit individuals with asthma by improving lung function and respiratory muscle strength. These exercises, which may include diaphragmatic breathing, pursed-lip breathing, and other techniques focused on controlled respiration, can help increase lung capacity and efficiency.

Practicing these exercises encourages better oxygen exchange and can enhance overall stamina and endurance during physical activities. By focusing on their breathing patterns, individuals with asthma can also learn to manage their symptoms, reduce the sensation of breathlessness, and develop greater comfort during exercise.

The other options may not provide the same level of benefit or could potentially exacerbate symptoms. For example, training at an increased intensity might not be advisable for someone with asthma, as it can lead to wheezing or shortness of breath. Mouth breathing can also be less effective than nose breathing, which filters and humidifies the air before it reaches the lungs. Lastly, while spending time in a sauna may seem relaxing, it does not specifically target the strengthening of lung function or breathing control, and high heat can sometimes trigger asthma symptoms in sensitive individuals.
