Patients with insufficient kidney qi are more likely to catch colds. This is because a deficiency in kidney qi can affect vitality, leading to slower bodily functions. Insufficient nurturing of vitality results in lethargy, lack of sleep, and reduced memory, thereby increasing the susceptibility to colds. This is especially true for male patients, where severe deficiency in kidney qi can lead to symptoms such as impotence and premature ejaculation. Additionally, it leads to lower bodily resistance and insufficient yang qi, as well as cold aversion, thus timely treatment is essential.
