Sleep deprivation is often treated as “insomnia” in traditional Chinese medicine (TCM). Insufficient qi and blood can cause sleep deprivation, but sleep deprivation is not always triggered by insufficient qi and blood, but is also seen in overwork and emotional stimulation. Lack of sleep can be reflected in the lack of sleep time and depth, such as old age and physical weakness or chronic illnesses that cause deficiency of qi, which cannot nourish the mind and spirit, can lead to sleep deprivation. In addition, such as overwork, overfeeding, overfeeding, overfeeding and other dietary injuries, anger and other emotional stimuli can also affect sleep, resulting in sleepless nights, or sleep and easy to wake up and so on. Sleep deprivation can be caused by a variety of factors, qi and blood deficiency is only one of them, the specific causes should be combined with related symptoms and other comprehensive judgment and analysis, not from the qi and blood deficiency alone, so as not to delay the condition.
