The risk of getting pneumonia in the elderly is much higher than in young and middle-aged people, and can be life-threatening if it progresses to severe pneumonia. Older adults have a lower immune system, poorer lung foundation, and are often combined with chronic lung diseases such as chronic obstructive pulmonary disease and chronic bronchitis, which have a high chance of developing into severe pneumonia once infected. Moreover, elderly people have weak Qi, and if they do not pay attention to breathing exercises normally, it is very difficult to expel sputum during pneumonia, and these are the factors that cause pneumonia to worsen. So early intervention must be dealt with.
